What a Fram cross reference number tells you
A Fram cross reference number is a lookup tool that matches your vehicle's year, make, and model to the correct Fram filter part number. Instead of searching through dozens of Fram products, you enter your car's information once and get back the exact filter that fits your engine and meets your vehicle manufacturer's specifications.
Fram publishes these cross references because their filter lineup is organized by part number, not by vehicle. A 2019 Honda Civic needs a different filter than a 2019 Ford F-150, and the cross reference tells you which Fram number covers each one. The reference also accounts for engine size — a Civic with a 1.5L engine may need a different filter than a Civic with a 2.0L engine from the same year.
This matters because using the wrong filter can restrict oil flow, cause leaks, or fail to filter properly. The cross reference ensures you buy a filter that your engine's oil system was designed to work with.
Key Takeaways
- Fram's online cross reference tool at fram.com lets you enter your vehicle year, make, model, and engine size to find your correct part number in seconds.
- You can also call Fram's customer service line or visit an auto parts store counter, where staff can look up your vehicle in their system and hand you the right filter.
- Your vehicle's owner manual lists the OEM filter specification, which you can cross-reference against Fram's product line to confirm the part number.
- Fram part numbers are printed on the filter box and on the filter itself, so you can verify you have the right one before installation.
- If you find conflicting information between sources, your vehicle manufacturer's specification in the owner manual takes priority over any third-party cross reference.
Using Fram's online cross reference tool
Fram maintains a cross reference search on their official website at fram.com. Navigate to their "Find Your Filter" or "Cross Reference" section — the exact link location changes occasionally, but it is always accessible from the homepage. You will see a form asking for year, make, model, and engine size.
Enter your information exactly as it appears on your vehicle registration or owner manual. If you are unsure of your engine size, check your owner manual or look at the engine bay — the displacement is usually stamped on the engine cover or listed on a sticker under the hood. Fram's tool will then display your correct part number, the filter's specifications, and often a photo so you can confirm it matches what you expect.
Write down the part number before you go to the store. This number stays the same across all Fram retailers, so you can use it at any auto parts chain or independent shop.
Getting a cross reference from auto parts retailers
Every major auto parts chain — AutoZone, O'Reilly, NAPA, Advance Auto Parts — has Fram filters in stock and can look up your vehicle in their system. Walk to the counter with your vehicle keys or registration and tell the staff member your year, make, and model. They will enter it into their computer and show you the Fram part number that matches.
This method is useful if you are already at the store and want to confirm the part number before buying, or if you prefer talking to a person rather than using an online tool. Many retailers will also show you the filter in person so you can see the size and connection type. If the store is out of stock, they can often order it for you and hold it.
Some independent repair shops and quick-lube facilities also keep Fram cross reference books or have access to the same lookup systems. If you are having your oil changed at a shop, they can tell you the part number they are installing.
Cross-referencing your owner manual against Fram's lineup
Your vehicle's owner manual specifies the oil filter type and sometimes the OEM part number. For example, it might say "Honda filter 15400-PLM-A02" or straightforward "Fram PH8A or equivalent." If your manual names a Fram part number directly, that is your answer — buy that number.
If your manual lists only the OEM manufacturer's part number (like the Honda example above), you can search Fram's website or call their customer service with that OEM number. Fram maintains cross references from OEM part numbers to their own, so they can tell you which Fram filter is equivalent. This method is slower than using Fram's vehicle lookup, but it is useful if you have an unusual vehicle or an older model that may not be in their online database.
Keep your owner manual handy during this process. It is the authoritative source for what your engine needs, and it settles any disagreement between different cross reference sources.
Verifying the part number on the filter box and filter itself
Once you have purchased a Fram filter, confirm the part number is printed on both the box and the filter canister before you install it. Fram prints the part number prominently on the top of the box and also on a label on the filter itself. If the number matches what you looked up, you have the right filter.
If the number does not match, do not install it. Return it to the store with your receipt. Mistakes at the warehouse or counter do happen, and it is much easier to exchange a filter before opening it than to remove an incorrect one from your engine.
Keep the box and receipt until after the oil change is complete and your engine has run for a few minutes. This way, if there is a leak or other problem, you have proof of what filter was installed and when.
What to do if you cannot find your vehicle in the cross reference
Fram's online tool covers most vehicles sold in North America from roughly the 1980s onward, but gaps exist. If your vehicle does not appear in their database, try these steps in order.
First, double-check your year, make, and model. Fram sometimes lists vehicles under slightly different names — for example, a "Chevy S-10" might be listed as "Chevrolet S-10" or vice versa. Try variations of the spelling or abbreviation.
Second, call Fram's customer service line. Their phone number is on the company website and on filter boxes. A representative can manually search their system and may have access to records not in the online tool. They can also help if your vehicle has multiple engine options and you are unsure which one you have.
Third, contact your vehicle's manufacturer directly or consult your owner manual. The manual will specify the correct filter type, and you can then ask an auto parts store to cross-reference that specification to Fram's current lineup.
Understanding Fram part number formats
Fram uses a letter-and-number system for most filters. Common prefixes include PH (spin-on filters for most vehicles), CH (cartridge filters), and WIX (Fram's commercial line). The numbers that follow indicate the filter's size, flow capacity, and thread size. For example, PH8A and PH3593 are both Fram filters, but they fit different engines and have different specifications.
The part number is the only reliable way to match a filter to your vehicle. Do not assume that two filters with similar names or prices are interchangeable — always verify the part number. Fram also makes filters under the Motorcraft brand for Ford vehicles and under other house brands for specific retailers, so the same filter may be sold under multiple names. The part number remains consistent across all of these.
If you are comparing Fram filters to other brands like Mobil 1, Bosch, or Purolator, each brand has its own part numbering system. You cannot directly compare part numbers across brands — you must cross-reference each brand separately to your vehicle, or ask an auto parts staff member to confirm that two filters from different brands are equivalent.
Frequently Asked Questions
Can I use a Fram filter if my owner manual recommends a different brand?
Yes. Your manual specifies the filter type and performance standard, not the brand. Fram filters that meet that standard are a valid choice. Many vehicle owners use Fram filters on vehicles whose manuals recommend OEM or other brands, as long as the Fram part number matches the specification.
What if Fram's online tool and an auto parts store give me different part numbers?
Contact Fram directly with both numbers and your vehicle information. One source may have outdated data or a data entry error. Your owner manual is the tiebreaker — whichever part number matches your manual's specification is correct.
Do I need to know my engine size to find the right Fram filter?
Yes, for most vehicles. Engine size is a required field in Fram's cross reference tool because the same year and model often come with multiple engine options, each needing a different filter. Check your owner manual, registration, or the engine bay for displacement in liters or cubic inches.
Can I use an older Fram filter I have left over from a previous vehicle?
Only if the part number matches your current vehicle's specification. Do not assume filters are interchangeable based on age or appearance. Look up your current vehicle's correct part number and compare it to the old filter's part number. If they do not match, the old filter will not work correctly.
Where can I find Fram's customer service phone number?
Fram's phone number is printed on every filter box and on their official website at fram.com. It is also listed on the packaging of Fram filters sold at auto parts stores. Call during business hours with your vehicle information and any part numbers you want to verify.
