FRAM Oil Filter Cross Reference: The Definitive Guide to Finding the Perfect Match​

Finding the correct cross reference for your FRAM oil filter is not just a matter of convenience; it is a critical step in ensuring your vehicle's engine receives the protection it needs from a compatible, high-quality filter. This guide provides a complete, practical resource for identifying equivalent oil filters from various brands that match your specific FRAM model, empowering you to make informed decisions for maintenance, emergencies, or cost-saving opportunities without compromising engine health. By understanding and using cross references accurately, you can maintain optimal performance and longevity for your vehicle.

​What is a FRAM Oil Filter?​​
FRAM is a well-established brand in the automotive aftermarket, known for producing a wide range of oil filters for cars, trucks, motorcycles, and other machinery. An oil filter's primary function is to remove contaminants from engine oil, such as dirt, metal particles, and sludge, which can cause wear and damage over time. FRAM filters are designed to meet or exceed original equipment manufacturer (OEM) specifications for various vehicles, offering different lines like the standard Extra Guard, the synthetic media Tough Guard, and the high-performance Ultra Synthetic. Each FRAM filter model is assigned a unique part number, such as ​FRAM PH3614​ or ​FRAM XG3614, which corresponds to specific engine applications and compatibility requirements. Using the right filter is essential because an incorrect fit or inadequate filtration can lead to oil leaks, reduced pressure, and severe engine damage.

​Understanding Oil Filter Cross Referencing​
Cross referencing in the automotive parts industry refers to the process of finding interchangeable parts between different brands. For oil filters, it means identifying which models from other manufacturers—like Mobil 1, K&N, Purolator, or Bosch—are direct equivalents to a given FRAM filter. This is possible because many filters are built to standardized dimensions and performance criteria for particular engine applications. However, not all cross references are perfect matches; subtle differences in materials, bypass valve settings, or anti-drain back valves can exist. Therefore, cross referencing serves as a valuable tool for finding alternatives, but it requires verification against your vehicle's needs. The process relies on databases, charts, and tools compiled from industry standards and manufacturer specifications.

​Why Cross Reference FRAM Oil Filters?​​
There are several practical reasons to use a FRAM oil filter cross reference. First, ​availability​ can be an issue: you might be in a remote location or a store that does not stock your usual FRAM filter, so knowing a compatible alternative from another brand allows you to proceed with an oil change without delay. Second, ​cost savings: sometimes, equivalent filters from other brands or generic suppliers are priced lower, and a cross reference helps you identify those options without guessing. Third, ​performance preferences: you may want to switch to a filter with different features, such as synthetic media for extended drain intervals, and cross referencing shows which models from premium brands match your FRAM filter's fit. Finally, for ​older or rare vehicles, FRAM might have discontinued a specific filter, but another brand could still produce an equivalent part. Cross referencing thus adds flexibility and security to your maintenance routine.

​How to Cross Reference FRAM Oil Filters: Step-by-Step Methods​
You can find cross references for FRAM oil filters through multiple reliable methods. Start by ​locating your FRAM part number, which is printed on the filter's housing or its packaging. This number is the key to all cross reference searches. Then, use one of these approaches:

• ​Manufacturer Websites and Catalogs: Many filter brands, including FRAM itself, provide online cross reference tools. Visit the FRAM website or sites of competitors like WIX or AC Delco, enter your FRAM part number, and they will list equivalent part numbers from their own and sometimes other lines. These tools are often updated and trustworthy.
• ​Automotive Parts Retailer Sites: Stores like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts have detailed parts catalogs on their websites. Enter your vehicle's make, model, and year, and they will show compatible filters, including FRAM and its cross references. Alternatively, search directly by the FRAM part number to see "fits also" or "compatible with" lists.
• ​Cross Reference Charts and Books: In physical auto shops, you might find printed cross reference charts or interchange manuals. These can be useful if internet access is limited. They compile data from manufacturers and are organized by part number.
• ​Professional Mechanic Databases: Services like ALLDATA or Mitchell 1, used by repair shops, include comprehensive parts interchange information. While these are subscription-based, they offer high accuracy for complex applications.
  Always ​double-check the results​ by comparing specifications such as thread size, gasket diameter, length, and pressure ratings. A match in part number does not always guarantee a perfect fit for every vehicle variant.

​Common FRAM Oil Filter Models and Their Cross References​
To illustrate practical cross referencing, here is a list of popular FRAM oil filter models and some of their widely accepted equivalents from other brands. This list is based on industry standards and manufacturer data, but you should confirm compatibility for your specific vehicle before purchase.

• ​FRAM PH3614: A common filter for many Ford, Mazda, and Honda vehicles. Cross references include ​Motorcraft FL-400S, ​Purolator L14610, ​Bosch 3312, and ​Mobil 1 M1-104. These share similar dimensions and application ranges.
• ​FRAM XG3614: The extended guard version for the same applications as PH3614. Equivalents include ​Purolator PL14610, ​WIX 51348, and ​K&N HP-1004. Note that some equivalents may use synthetic media.
• ​FRAM PH3682: Frequently used for certain GM and Saab engines. Cross references are ​AC Delco PF46, ​Purolator L14476, and ​STP S3682.
• ​FRAM PH8A: A classic filter for older American V8 engines. Compatible parts include ​Motorcraft FL-1A, ​Purolator L20048, and ​Baldwin B2.
• ​FRAM TG3600: From the Tough Guard line for synthetic oil. Matches with ​Purolator ONE PL14610, ​WIX XP 51348, and ​Amsoil EA15K.
  Remember that ​cross references can vary by region and production year, so always verify with your vehicle's manual or a trusted source. This list is a starting point, not a definitive guarantee.

​Critical Factors to Verify for Compatibility​
When using a cross reference, do not rely solely on part number matches. Several technical specifications must align to ensure the alternative filter works safely in your engine. First, ​thread size and pitch​ are paramount: if the threads do not match the engine block's oil filter mount, the filter will not screw on properly, leading to leaks or damage. Second, ​gasket diameter and material​ affect the seal; a mismatched gasket can cause oil to seep out. Third, ​overall dimensions—length and width—must fit within the engine compartment without interfering with other components. Fourth, ​pressure ratings​ matter: the filter must handle your engine's oil pressure, especially in high-performance or diesel applications. Fifth, check for ​valve types: most filters have an anti-drain back valve to prevent oil from draining out when the engine is off, and a bypass valve to allow oil flow if the filter is clogged. These valves must operate at correct pressures. Use manufacturer spec sheets or consult a mechanic if unsure.

​The Role of Quality in Oil Filter Selection​
Cross referencing should not lead you to compromise on quality. FRAM filters are built to specific standards, and when switching to an equivalent, consider the brand's reputation and construction. ​Budget filters​ from unknown brands might list as cross references but could use inferior materials like cardboard end caps or weak adhesives, which can fail under heat and pressure. Stick to reputable brands such as Mobil 1, WIX, Purolator, or Bosch when possible. Look for features like synthetic filter media, durable housings, and silicone anti-drain back valves for better performance. In general, ​you get what you pay for: a cheaper alternative might save money upfront but risk engine damage. For modern engines with tight tolerances, using a high-quality filter that meets OEM specs is non-negotiable. Always prioritize protection over price.

​Where to Find Reliable Cross Reference Information​
Access to accurate data is key for successful cross referencing. Here are trusted sources:

• ​Official Brand Websites: FRAM's site (fram.com) has a cross reference tool under "Product Finder." Similarly, sites for brands like Purolator or K&N offer interchange tools. These are primary sources.
• ​Automotive Forums and Communities: Enthusiast forums for your vehicle make (e.g., Ford-trucks.com or Honda-tech.com) often have threads where users share cross reference experiences. While helpful, treat this as secondary information and verify with official sources.
• ​Parts Store Employees: Staff at local auto parts stores can access detailed catalogs and may provide cross references. However, human error is possible, so ask for printed or digital confirmation.
• ​Online Marketplaces: Sellers on eBay or Amazon sometimes list cross references in product descriptions. Use this cautiously, as it may be inaccurate. Stick to listings from reputable sellers.
• ​Vehicle Service Manuals: Your car's manual might list approved filter part numbers from various brands, serving as a reliable cross reference.
  For critical applications, ​consult a professional mechanic​ who can use professional databases and hands-on experience to confirm matches.

​Practical Tips for Using Cross References Safely​
To avoid mistakes, follow these best practices. First, ​always keep the old filter​ during an oil change until you have confirmed the new one fits perfectly. You can compare the old and new filters side by side for dimensions and gaskets. Second, ​check for vehicle-specific recalls or updates: sometimes, manufacturers issue revised filter specifications for certain model years, so a general cross reference might not apply. Third, ​use multiple sources: cross-check a part number across two or three tools to ensure consistency. Fourth, ​beware of generic "one-size-fits-all" filters​ that claim to fit many applications; they often require adapter rings and may not seal correctly. Fifth, ​test fit the filter before adding oil: if possible, screw on the new filter (without filling oil) to ensure it threads smoothly and seats properly. This can prevent leaks after the oil change is complete. By being meticulous, you can use cross references effectively without risks.
