Shopify Auto Parts Store: Adding a Year/Make/Model Search

An auto parts store lives or dies on one question the shopper asks before anything else: will this part fit my car? A clothing store sorts by size; a parts store has to match each product against years, makes and models of vehicles, often dozens of them per part. That matching is called fitment, and on Shopify it is the main build decision.

This guide is for a parts seller opening a Shopify store or moving one from a marketplace. It covers what Shopify does natively, where fitment data comes from, the apps that add a year/make/model search, the themes and running costs, and the rules that are specific to parts: card payments, hazardous shipping, wrong-fit returns, core charges and US emissions law.

Does Shopify Have a Year/Make/Model Search Built In?

Start with what is missing, because it decides everything after it. No Shopify page we have found describes a native year/make/model fitment attribute — as of September 27, 2026, this reads off Shopify's Search & Discovery filter documentation, its category metafield pages and the vehicles-and-parts files of the Standard Product Taxonomy, where the vehicle attributes on parts categories, such as motor vehicle type and fit type, describe the kind of vehicle and the kind of fit rather than a year, make or model.

What the native tools can do

Three native tools matter for a parts catalog, and none of them costs extra:

• Category attributes. Assign a product category and Shopify creates its standard attributes for you: per the Search & Discovery filter documentation, they "are automatically created as product metafield definitions when you assign a category to your products."
• A vehicle-type attribute. On parts categories such as motor vehicle exhaust, the taxonomy offers Motor vehicle type, with values such as car, SUV, truck and van. It describes the kind of vehicle, not a year, make or model. Categories such as motor vehicle parts, lighting and interior fittings also carry Fit type, with the values custom, direct, universal and other; it names no year, make or model either.
• Metafield filters. The free Search & Discovery app turns metafields into storefront filters, and the value types it accepts include Single line text (List) and Metaobject reference (List), so one product can carry several values in one field.

Shopify's filter documentation sorts metafield filters by the products a metafield is assigned to: category metafield filters "are based on product metafields that are assigned to specific product categories", and product metafield filters are described this way:

Two ceilings apply: a store can have up to 25 filters in total, standard and custom together, and a collection that holds more than 5,000 products shows no filters at all. A large parts catalog therefore needs smaller collections, and the other limits that decide whether a filter appears are set out in the ceilings on Search & Discovery filters.

Why separate make, model and year filters mislead

A car on a dealer's lot is one vehicle, so its make, model and year sit in one set of fields, and ordinary filters work; that is the setup behind make, model and year filters for car listings. A part is the opposite case: one brake kit can fit several models across several years.

Store that kit's fitment as three lists — makes, models, years — and each filter checks its own list separately. Suppose the kit fits the Civic in its early model years and the Accord in later ones. The years list now holds both ranges, so a shopper who picks Accord and an early year still sees the kit, although it does not fit that car.

Whether a given metafield type can become a filter at all, and which ones cannot, is answered in which metafields can be used as filters. For most parts sellers, though, the many-vehicles problem is the reason to move to an app.

Where Fitment Data Comes From: ACES, PIES and Your Supplier

The Auto Care Association describes the standard that matters most for a year/make/model search:

Its companion, PIES, the Product Information Exchange Standard, carries the product information that is not fitment. The Auto Care Association describes both as maintained by the industry, for the industry, through industry workgroups and its Technology Standards Committee.

If your suppliers don't send files directly, SEMA Data is one place that holds this data for both brands and resellers; it describes itself to brands as a catalog platform, a PIM and a distribution engine in one. It also publishes a SEMA Data Scorecard that measures the quality and completeness of the product and technical data manufacturers share, which is worth checking before you build a storefront on a brand's data.

Ask each supplier which format they send before you pick an app. An ACES/PIES file and a spreadsheet lead to different apps in the next section; no data at all means getting it first, from your suppliers or a platform such as SEMA Data, before any app can help.

Which Shopify Apps Add a Year/Make/Model Search?

The table is a snapshot of six listings as they read on September 27, 2026, not a ranking and not the whole App Store. The fitment column shows the import format a listing names; "Ask the developer" marks the listings whose format you should confirm with the developer before you install.

What to check before you install one

• How shoppers search. A year/make/model dropdown covers most stores; VIN, license plate or HSN/TSN lookup matters when buyers know their vehicle by a number rather than a name.
• A saved vehicle. FitmentPro lists My Garage from its $9.99 tier, which "lets shoppers save their vehicles and shop matching parts", and SPT and Convermax list a garage too — useful when the same buyers return for the same car.
• The import format. SPT names ACES/PIES, ShowMeTheParts and CSV; Convermax names ACES/PIES files and spreadsheets; FitmentPro names Excel and CSV import from its $9.99 tier. For the other three, ask the developer how fitment data gets in before you commit a catalog.
• Who owns the data. Convermax states on its listing, "We don't sell a fitment database or own your data. We connect to it." Know whether an app holds your fitment or reads it from your files, because that decides how hard leaving it would be.
• The tier. Prices run from free to install to $850 a month; read which tier holds the features you need on the listing itself.

Is There a Shopify Theme for Auto Parts Stores?

Inside the Theme Store, Meka presents itself "For Auto, Cars, Auto Parts, Car Parts, Mobile Automotive, Tools, Car", and Krank's Drive preset is "Built for Automotive" and "Perfect for auto parts, accessories, and performance shops". Those are the two we read; both describe design, and neither description mentions a vehicle finder or year/make/model search.

That makes the theme a layout decision rather than a fitment one: the selector will come from your app either way. Judge a theme by how its collection page shows filters on a long catalog, and start the comparison from Horizon, Shopify's current flagship theme, before paying for an automotive preset.

What Does an Auto Parts Store Cost to Run?

The platform costs the same as for any store. The entry plan, Basic, is $39 a month billed monthly, or $29 a month billed yearly, in USD as of September 2026. What a parts store adds is the fitment layer.

Take two stacks as the worked example. Add the entry plan's monthly price to the cheapest priced fitment tier in the table ($9.99) and the store runs $48.99 a month before a theme or data. Swap in Convermax's entry tier ($250), the lowest paid tier of the two apps whose listings name ACES/PIES import, and the same stack runs $289 a month.

The $9.99 tiers carry limits: FitmentPro's lists up to 100 products with vehicle fitment and Metizsoft's up to 2,000 fitment rows, while Convermax's entry tier lists 250,000 products.

The rest of the build — domain, pages, checkout, policies — follows the same steps as any Shopify store website, so the money decision a parts seller actually faces is which fitment tier the catalog needs.

Can You Take Card Payments for Car Parts on Shopify?

Two layers decide whether you can take cards for parts. The first is Shopify's own: its Shopify Payments eligibility page groups prohibited businesses into six high-level categories — regulated or illegal products, financial products, adult products, pseudo-pharmaceuticals, gambling and counterfeit goods — and, as read on September 27, 2026, car parts are not one of them. Shopify notes that the list isn't exhaustive and varies depending on your region.

The second is the processor behind Shopify Payments in your country. Adyen's list carries the line "Car and truck rental / sales / importers / car parts", marked R for merchants and for platform businesses. If Adyen processes Shopify Payments where you sell, check what that means for you before building the store; what a processor restriction means in practice is set out in which Shopify Payments processors restrict vehicle sales.

Shipping Heavy and Hazardous Parts

A parts catalog mixes small boxes with car batteries, spray cans and exhaust systems. Two different rules apply to them, and the first is the one that stops a label from printing at all.

Can you ship car batteries and aerosols on a Shopify label?

Shopify's page on shipping dangerous goods gives everyday examples of household products that might be classified as hazardous materials when shipped, several of which sit in a parts catalog:

• Batteries.
• Aerosols, such as spray paints.
• Flammable liquids, such as paint thinners.

For an item that counts as hazardous, the USPS label page says shipping labels do not support hazardous materials, and that such shipments are prohibited and must be shipped through USPS directly, for domestic and international mail alike.

The FedEx label page says Shopify's labels don't support hazardous materials for domestic FedEx shipments either. The block belongs to Shopify's label channel, not to the carrier, as our answer on shipping lithium batteries with Shopify Shipping explains; for a hazardous part, open an account with the carrier and ship under its own rules.

Heavy and oversized parts

Bumpers, exhaust systems and wheel sets run into the size and weight limits of a Shopify Shipping label, and those limits are set by each carrier and service rather than by Shopify. Check each heavy part against them before you promise delivery; the options when a part is larger than every label allows are set out in what to do when a package is bigger than every option.

Wrong-Fit Returns and Core Charges

Every fitment mistake ends as a return, and parts add a second kind of refund most stores never see: the core. Shopify covers the first with settings; the second is your policy.

How to set return rules for parts that don't fit

Shopify's return rules set the defaults that apply to most items, in three types:

• Return window — how long after purchase a buyer can send a part back.
• Return shipping costs — who pays for the trip back.
• Restocking fee — what you keep from a refund.

With self-serve returns on, a buyer submits the request from their order status page without contacting you, and you approve or decline it based on your policies. How each of those return rules behaves, and what the window counts from, is laid out in how Shopify's return rules work in practice.

For a parts store, write the wrong-fit case into the policy explicitly: whether an uninstalled part that did not fit carries a restocking fee, and who pays return shipping when the fitment data, not the buyer, was wrong.

Does Shopify support core charges?

A core charge is the deposit a buyer pays until the old part comes back. No Shopify Help Center page we have found describes a core charge or core deposit as a built-in feature — as of September 27, 2026, this reads off its return rules, self-serve returns, refunds and returns, Shopify Payments eligibility, partial payments and purchase options pages — so decide before launch how you charge a core and how you refund it when the old part arrives, and put those terms in your returns policy where buyers see them before paying.

Emissions Parts: CARB and EPA Rules for US Sellers

Performance and emissions parts carry a legal layer the storefront cannot handle for you. This is orientation from the regulators' own pages, not legal advice: the state rule reaches parts offered to California, and the federal one applies across the US.

California: do your parts need a CARB Executive Order?

California's Vehicle Code §27156(c) says no person shall install, sell, offer for sale or advertise a device that alters or modifies the original design or performance of a required motor vehicle pollution control device or system. The way a part gets out from under that rule is an exemption, which CARB describes like this:

Every Executive Order part has an assigned number that Smog Check stations, BAR Referee stations or CARB can verify, so record the number for each part you offer to California buyers and show it on the product page.

An Executive Order allows the part to be installed on specific emission controlled vehicles, so check that the vehicles in your fitment data are the ones the order covers. Catalytic converters get no shortcut: CARB's aftermarket catalytic converter page says they must be exempted from California's anti-tampering laws to be legally sold and installed in the state.

Federal: the EPA ban on defeat devices

Federal law reaches every US seller, and the EPA's fact sheet states the prohibition in full. The phrase that matters for a store is "offer to sell", not only "sell".

The same fact sheet names three ways to have a reasonable basis for selling an aftermarket part:

1. The part is identical in design and function to the part it replaces.
2. The vehicle, as modified, meets emissions standards when tested on the same tests as the original vehicle manufacturer used to certify the vehicle with EPA.
3. You can produce an Executive Order from the California Air Resources Board that covers the same device on the same vehicle on which the device is installed.

Civil penalties are counted per violative vehicle, engine or defeat device, so they grow with every unit sold. Keep the evidence for each emissions-related part on file before it goes live.

Set Up Your Parts Store in This Order

The order matters because the first two steps can remove products or a payment route before any build work starts, and the fitment steps depend on the data you receive. Tick each step off as you go; the list keeps your progress in this browser.

The Bottom Line

The platform part of a parts store is ordinary. The fitment part is not, and it is decided by two facts about your catalog: how many vehicles each part fits, and the format your suppliers send.
