Your Complete Guide to FRAM Oil Filter Cross Reference and Replacement​

2026-01-06

Finding the correct cross-reference for your FRAM oil filter is a straightforward process essential for maintaining your vehicle’s engine health. You can successfully identify compatible filters from brands like Mobil 1, K&N, Bosch, Purolator, and WIX by using your existing FRAM part number, your vehicle’s specifications, or trusted online cross-reference tools. ​The most reliable method is always to start with your current FRAM part number.​​ This guide will provide you with all the practical knowledge needed to navigate oil filter cross-referencing confidently, ensuring you choose the right filter for your car, truck, or motorcycle.

Understanding Oil Filter Cross-Referencing
Cross-referencing is the practice of finding parts from different manufacturers that are functionally interchangeable. In the context of oil filters, a FRAM TG6607, for example, will have direct equivalents from other companies that match its physical dimensions, thread size, gasket design, and bypass valve specifications. This system exists because while vehicle manufacturers produce engines, they rely on parts suppliers like FRAM to produce the actual filters. Multiple aftermarket companies then produce filters to fit those same OEM specifications. Cross-referencing empowers you to shop based on brand preference, price, availability, or specific filter technology without being locked into a single brand.

Why Accurate Cross-Reference is Critical
Using an incorrectly cross-referenced filter can lead to severe engine damage. Consequences include:

  • Leaks:​​ A mismatch in gasket size or location can cause oil to leak externally.
  • Bypass Issues:​​ An incorrect bypass valve pressure setting can allow unfiltered oil to circulate or restrict oil flow.
  • Improper Fitment:​​ Wrong thread pitch or canister dimensions can prevent proper sealing or even physical installation.
  • Reduced Filtration:​​ A filter with different media or capacity may not protect your engine effectively.

Therefore, verifying your cross-reference match through multiple sources is not just a suggestion—it is a necessary step for engine protection.​

Primary Method: Using Your Existing FRAM Part Number
This is the simplest and most accurate starting point. Locate the part number printed directly on the filter canister or its box (e.g., PH6607, XG3600, TG4386).

  1. Visit the official ​FRAM Product Catalog​ on their website. Enter your part number. The product page will often list vehicle applications and sometimes direct OEM numbers.
  2. Use trusted automotive parts websites like RockAuto, AutoZone, O'Reilly, or Advance Auto Parts. Enter the FRAM number into their search bar. These sites typically display "You may also fit" or "Comparable to" lists, showing direct equivalents from other brands.
  3. Consult professional-grade cross-reference databases used by mechanics, such as those from WIX or Purolator. Many of these are accessible online.

Secondary Method: Using Your Vehicle Information
If you don’t have an old filter, use your vehicle’s details.

  1. Gather your vehicle’s ​exact year, make, model, and engine size.​​ This information is crucial.
  2. Go to any major parts retailer website. Input your vehicle details to see a list of all recommended oil filters.
  3. Note the FRAM part number suggested for your vehicle. Then, use that number to cross-reference to other brands as described in the primary method. This two-step process helps confirm compatibility.

How to Use Online Cross-Reference Tools Effectively
Digital tools streamline the process, but you must use them correctly.

  • Retailer Websites:​​ As mentioned, sites like RockAuto are excellent. They show side-by-side listings for all compatible brands for your vehicle.
  • Filter Manufacturer Websites:​​ Competitors like Bosch, Mobil 1, and WIX have their own vehicle lookup tools. You can input your car info on the Mobil 1 site to find their filter, which will be a cross-reference for the equivalent FRAM.
  • Dedicated Cross-Reference Sites:​​ Some websites are built specifically for part number interchange. Caution is advised here; ​always double-check the results from a secondary source, such as a major retailer, to confirm accuracy.​​ Do not rely on a single, unverified source.

Comparing FRAM with Other Major Brands
Understanding how FRAM filters compare can help you decide on an alternative.

  • Mobil 1:​​ Often positioned as a premium synthetic media filter. A Mobil 1 M1-108 will typically cross to a FRAM Ultra Synthetic XG10808. Mobil 1 filters are known for high capacity and synthetic media.
  • Bosch:​​ Offers a range from economy to premium. A Bosch 3323 is a direct match for the popular FRAM PH6607. Bosch filters are widely available and often competitively priced.
  • Purolator:​​ One of the oldest filter brands. Purolator's classic L30001 is synonymous with the FRAM PH6607. Their PurolatorONE and BOSS lines are direct competitors to FRAM's Extra Guard and Ultra Synthetic.
  • WIX / NAPA:​​ WIX is renowned for its robust construction and filter media. NAPA Gold filters are manufactured by WIX. A WIX 57060 is a cross for FRAM PH6607. They are highly regarded in the professional mechanic community.
  • K&N:​​ Known for high-flow performance filters often featuring a welded nut for easy removal. A K&N HP-2004 will cross to others in its size group. K&N filters may use a different media philosophy focused on flow.
  • ACDelco:​​ The OEM supplier for General Motors vehicles. An ACDelco PF63 is the OEM filter for many GM V8s and has direct FRAM equivalents like the TG4386.

Important Technical Specifications to Verify
When you find a potential match, verify these key specs. This information can be found on manufacturer specification sheets.

  • Thread Size:​​ The diameter and pitch of the center thread (e.g., 3/4"-16). ​This must be identical.​
  • Gasket Outer Diameter (OD):​​ The size of the sealing ring.
  • Gasket Inner Diameter (ID):​​ The inner measurement of the sealing ring.
  • Height:​​ The overall canister height. Slight variations (1-2mm) can sometimes be acceptable, but significant differences are not.
  • By-Pass Valve Pressure Setting:​​ The pressure at which the valve opens (e.g., 8-11 PSI). This should be very close to the original specification.
  • Anti-Drain Back Valve:​​ Ensure the candidate filter has one if your engine requires it.

Step-by-Step Verification Process Before Purchase

  1. Identify:​​ Obtain your FRAM part number or precise vehicle details.
  2. Research:​​ Use the FRAM catalog and 2-3 retailer websites to generate a list of potential cross-reference part numbers from other brands.
  3. Cross-Check:​​ Verify the list is consistent across all sources. If one part number appears on one site but not others, investigate why.
  4. Spec Check:​​ For the top 2-3 candidates, locate and compare their technical specification sheets. Confirm thread size, gasket dimensions, and height match.
  5. Physical Comparison (If Possible):​​ If you have the old filter, take it to the store and visually compare it to the new box. Check the gasket and threading.

  • Relying on a Single Source:​​ Always double-check.
  • Overlooking Quality Tiers:​​ Remember that each brand offers different quality levels (economy, standard, synthetic). Ensure you are comparing equivalent tiers (e.g., FRAM Ultra Synthetic to Mobil 1 Extended Performance, not their basic models).

Frequently Asked Questions on FRAM Cross-Reference

  • Is the more expensive filter always the better cross-reference?​​ Not necessarily. The correct cross-reference is defined by specifications, not price. Choose the quality tier (conventional, synthetic blend, full synthetic media) that fits your maintenance schedule and driving conditions.
  • Can I use a cross-referenced filter if the height is slightly different?​​ A minor difference (e.g., 1-2mm) is usually acceptable if all other specs match, as it often indicates a difference in canister design, not sealing surfaces. ​However, if in doubt, choose the filter with the exact same height.​
  • Why does my FRAM filter have two part numbers?​​ FRAM may list an internal number and a "EZ" number (like PH6607 vs. PH16). Use the primary part number (PH6607) for cross-referencing.
  • Are all filters that cross-reference to my FRAM filter truly equal?​​ They are functionally interchangeable in fit and basic function, but they can differ in internal materials, media type, capacity, and construction quality. This is why comparing filter technology within your price range is important.

By following this structured approach—starting with your FRAM part number, using multiple reputable sources for verification, and checking key technical specifications—you can confidently and safely find the perfect oil filter cross-reference for your vehicle.
