What a CarQuest cross reference filter lookup does

A cross reference is a tool that matches a filter from one brand to an equivalent filter from another brand. CarQuest, an automotive parts distributor, maintains cross reference tables so you can find the CarQuest part number that replaces or matches a filter you already know by a different name. If you have a Fram, Motorcraft, or Bosch filter number, you can use CarQuest's system to find what CarQuest calls that same filter — or find what other brands call a CarQuest filter you're holding.

This matters because the same physical filter often has multiple part numbers depending on who made it and who is selling it. A filter that works in your engine might be labeled as a Fram PH3593A at one store and a CarQuest 85047 at another. The cross reference tells you those two numbers describe the same filter.

Key Takeaways

  • CarQuest's online cross reference tool lets you search by your current filter's brand and part number to find the CarQuest equivalent.
  • You can also search by vehicle year, make, and model if you don't have a filter number in front of you.
  • CarQuest filters are often rebranded versions of filters from major manufacturers, so the physical filter may be identical even though the part number changes.
  • A CarQuest store associate can run a cross reference lookup by phone or in person if you bring the old filter or its part number.

Using CarQuest's online cross reference tool

Start at carquest.com and look for the "Cross Reference" or "Parts Lookup" section — the exact location shifts with website updates, but it is typically in the main navigation or under a "Tools" menu. Click into the cross reference tool.

You will see a search field asking for a part number. Type in the brand and number of the filter you currently have or want to match. For example, if you have a Fram filter, type "Fram PH3593A" or just "PH3593A". CarQuest's system will return the CarQuest part number and often show you other brands that cross to the same filter.

If you do not have a filter number, use the vehicle lookup instead. Enter your vehicle's year, make, model, and engine size. CarQuest will show you all the filters that fit your vehicle, including oil filters, air filters, and cabin air filters. This route takes longer but works if your old filter is missing or the number is worn off.

What information you need before you search

The easiest path is to have the old filter in your hand. Look for a part number printed or stamped on the filter itself — it is usually on a label or embossed into the plastic or metal. Write down the brand name and the full part number exactly as it appears.

If the filter is too dirty to read or you threw it away, you can use your vehicle's year, make, model, and engine displacement instead. You will find this information on your vehicle registration, in your owner's manual, or by searching your vehicle identification number (VIN) on a site like edmunds.com or cars.com. CarQuest's vehicle lookup will narrow down to the correct filter from there.

Some filters have multiple versions for the same vehicle — for example, one for a standard engine and another for a turbocharged engine. Having the engine size or type prevents you from getting the wrong match.

Searching by vehicle instead of part number

If you do not have a filter number, CarQuest's vehicle lookup is faster than calling a store. On the CarQuest website, select "Find Parts by Vehicle" or a similar option in the main menu. Enter your vehicle's year, make, and model in the fields provided.

CarQuest will ask you to select your engine type or size from a dropdown. Choose the option that matches your vehicle — this step matters because different engines in the same model year may need different filters. Once you confirm, CarQuest shows you all available filters for that vehicle, organized by type (oil, air, cabin air, transmission, etc.).

Click on the filter type you need. CarQuest will display the CarQuest part number, the price, and often a list of other brands that cross to the same filter. You can then take that CarQuest number to a store, order it online, or call ahead to confirm stock.

Getting help from a CarQuest store associate

If the online tool is not working or you prefer to speak with someone, call your local CarQuest store or visit in person. Bring the old filter with you if you have it — an associate can read the part number directly and look it up in their system in seconds.

If you do not have the filter, tell the associate your vehicle's year, make, and model. They will ask about your engine type and then pull up the correct filter. Many CarQuest stores can also cross reference filters over the phone, so you do not have to make a trip if you already know your vehicle information.

Store associates sometimes know which filters are in stock and which are on order, information that the website may not show in real time. If you need a filter urgently, calling ahead saves you a wasted trip.

Understanding what the cross reference results mean

When CarQuest's system returns a match, you will see the CarQuest part number first, followed by the price and sometimes a list of equivalent brands. For example, a CarQuest result might show "CarQuest 85047 — Fram PH3593A, Motorcraft FL400, Bosch 3323." This means all four of those part numbers fit the same filter and will work in the same vehicles.

The physical filter inside the box is often identical across brands — CarQuest frequently rebrands filters made by the same manufacturer. The difference is the box, the label, and the part number. A CarQuest filter and a Fram filter with the same cross reference will perform identically in your engine.

Price may vary between brands even when they cross reference to the same filter. CarQuest filters are sometimes cheaper than name brands, sometimes more expensive, depending on the specific filter and current promotions. The cross reference tells you they are equivalent, not that they cost the same.

What to do if you cannot find a match

If CarQuest's online tool returns no results, the part number may be misspelled or the filter may be too old or too new for the database. Try searching without the brand name — just type the numbers and letters. CarQuest's system sometimes recognizes partial numbers.

If that does not work, call a CarQuest store directly. Provide the part number exactly as it appears on the filter, and the associate can search their full database or contact CarQuest's customer service line. They may also be able to tell you if the filter is discontinued or if a newer equivalent exists.

Another option is to search the filter brand's website directly. Fram, Motorcraft, Bosch, and other major manufacturers have their own cross reference tools. If you find the match on their site, you can then search CarQuest for that CarQuest part number.

Frequently Asked Questions

Can I use a filter with a different part number if it physically fits?

Not safely. Filters with different part numbers may have different flow rates, bypass valve settings, or media materials, even if they appear similar. Always use a filter that cross references to your vehicle's specification. Using the wrong filter can reduce engine protection or damage your engine over time.

Does CarQuest's cross reference work for filters from other countries?

CarQuest's database focuses on filters sold in North America. If you have a filter from a European, Asian, or other international brand, it may not appear in CarQuest's system. Try the manufacturer's website or contact CarQuest directly to see if a North American equivalent exists.

What if my old filter number is partially worn off?

Use your vehicle information instead. CarQuest's vehicle lookup does not require a part number — just your year, make, model, and engine size. This method is slower but will get you to the right filter without needing to read a damaged label.

Are CarQuest filters the same quality as name brands?

CarQuest filters are often manufactured by the same companies that make name-brand filters. The physical filter is frequently identical, but the packaging and labeling differ. Price and warranty may vary, so compare the specifications and warranty terms rather than assuming a cheaper CarQuest filter is lower quality.

Can I cross reference a filter I bought at another store to find the CarQuest version?

Yes. Type the brand and part number from your current filter into CarQuest's cross reference tool. The system will show you the CarQuest equivalent and any other brands that match. This is useful if you want to switch to CarQuest for price or convenience.
