How to find your Briggs and Stratton oil filter using a cross reference

A cross reference is a tool that matches one part number to another — in this case, matching your Briggs and Stratton engine model to the oil filter that fits it. Instead of hunting through a manual or calling a dealer, you can look up your engine's model and displacement (measured in cubic centimeters or cc) and find the correct filter number in seconds. Briggs and Stratton publishes these cross references on their website and in printed spec sheets, and many retailers like Amazon, Tractor Supply, and Ace Hardware include them in their product listings.

The reason you need a cross reference is that Briggs and Stratton does not make all its own filters — they source them from manufacturers like Fram, Kohler, and Donaldson. The same physical filter might be sold under different brand names. A cross reference tells you which aftermarket filter will work in your engine without guessing or buying the wrong part.

Key Takeaways

  • Your engine's model number and displacement (cc) are the two pieces of information you need to find the correct filter.
  • Briggs and Stratton's official cross reference chart is available as a PDF on their website under technical documentation.
  • Common replacement filters include Fram PH3593, Kohler 12 050 01, and Donaldson P502025, but the right one depends on your specific engine.
  • If you cannot find your model in the chart, calling a Briggs and Stratton dealer or the manufacturer's customer service line will give you a definitive answer.
  • Aftermarket filters that cross-reference correctly are safe to use and often cost less than OEM (original equipment manufacturer) filters.

Where to find your engine's model and displacement number

The model and displacement are stamped or printed on a label attached to the side or top of your engine. On push mowers, look on the back of the engine block. On riding mowers and small equipment, check the frame near where the engine bolts down. The label will show a model number (usually starting with numbers like 12, 14, 16, or 18) and a displacement in cc — for example, "Model 12H802, 389 cc."

Write both numbers down before you search. If the label is worn or missing, you can sometimes find the information on the equipment's original paperwork or by searching the serial number on Briggs and Stratton's website. Some retailers will also identify your engine from a photo if you post it in their customer service chat.

Using Briggs and Stratton's official cross reference PDF

Briggs and Stratton publishes a free cross reference document on their website at briggs-stratton.com. Go to the Support or Technical Resources section, then look for "Oil Filter Cross Reference" or "Parts Cross Reference." The PDF is organized by model number and lists the OEM filter part number alongside compatible aftermarket filters from Fram, Kohler, and others.

Once you have the document open, search (Ctrl+F on Windows, Command+F on Mac) for your model number. The chart will show you the Briggs and Stratton part number first, then the equivalent filters you can buy at any auto parts store. Write down all the options — you may find that one is cheaper or more readily available than another.

Common oil filters that cross-reference to Briggs and Stratton engines

The filters that appear most often in cross references are Fram PH3593, Kohler 12 050 01, and Donaldson P502025. These are not the only options, and not all of them fit every engine, but they are widely stocked and reasonably priced. Fram filters are sold at Walmart, Target, and most auto parts chains. Kohler filters are common at Tractor Supply and John Deere dealers. Donaldson filters are often found at industrial suppliers and online retailers.

Before you buy, confirm that the filter you are looking at matches the cross reference for your specific model. A filter that fits a 12H802 may not fit a 16H432, even though both are Briggs and Stratton engines. The cross reference is your may provide that the filter will thread on correctly and filter the right volume of oil for your engine.

What to do if your model is not in the cross reference chart

Older engines or specialty models sometimes do not appear in the standard cross reference. In that case, contact Briggs and Stratton's customer service line at 1-800-233-3723. Have your model number and displacement ready. A representative can tell you the correct filter part number and may be able to suggest where to buy it.

You can also reach out to a local Briggs and Stratton authorized dealer — most small engine repair shops are authorized dealers and keep cross reference information on hand. They may charge a small fee for the lookup, but they can also inspect your engine to make sure you are buying the right part.

Aftermarket versus OEM filters: cost and performance

An OEM filter is made by Briggs and Stratton or to their exact specifications. An aftermarket filter is made by a third-party manufacturer but meets the same performance standards. Both are safe to use in your engine as long as the cross reference confirms they fit.

Aftermarket filters usually cost 30 to 50 percent less than OEM filters. A Fram or Kohler filter that cross-references to your engine will filter your oil just as well as a Briggs and Stratton-branded filter. The main difference is the box and the brand name on the can. If budget is a concern, the cross-referenced aftermarket option is a solid choice. If you prefer to stick with the original brand, the cross reference will also show you the OEM part number so you can order directly from Briggs and Stratton or an authorized dealer.

How to verify the filter fits before you install it

When your filter arrives, check the threading and diameter against your engine before you install it. The filter should thread onto the engine's filter head smoothly — if it does not catch or feels loose, stop and double-check the part number. The diameter should be close to your old filter; a filter that is significantly larger or smaller is a sign you may have the wrong part.

If you ordered online and the filter does not fit, most retailers will accept a return within 30 days. Keep your receipt and the original packaging so you can exchange it for the correct part. A few minutes of verification before installation saves you the frustration of draining the engine and starting over.

Frequently Asked Questions

Can I use a filter from a different brand if the cross reference says it fits?

Yes. A cross reference confirms that the filter will thread on correctly and handle the oil flow your engine needs. Fram, Kohler, Donaldson, and other brands that appear in the cross reference are all safe choices. The filter does the same job regardless of the brand name.

What if I buy the wrong filter by mistake?

Do not install it. Return it to the retailer for an exchange or refund. Installing the wrong filter can cause oil leaks or restrict oil flow to your engine, both of which damage the engine over time. It is worth the trip back to the store to get the right part.

Is the cross reference the same for all Briggs and Stratton engines?

No. Different model numbers and displacements require different filters. Always look up your specific model and cc rating. Using a filter from a similar engine is a common mistake that can lead to leaks or poor filtration.

Where can I buy the filters listed in the cross reference?

Most cross-referenced filters are sold at Walmart, Target, Amazon, Tractor Supply, Ace Hardware, and auto parts chains like AutoZone and O'Reilly. You can also order directly from Briggs and Stratton's website or from an authorized dealer. Prices vary by retailer, so it is worth checking a few before you buy.

Do I need to change the filter every time I change the oil?

Yes. The filter traps dirt and debris as oil circulates through your engine. A clogged filter restricts oil flow and reduces engine protection. Most small engines need an oil and filter change every 50 to 100 hours of use, or at least once a season. Check your owner's manual for the exact interval for your model.
