Kawasaki 49065-0721 Oil Filter Cross Reference Guide
The Kawasaki 49065-0721 cross references to the FRAM PH8170, WIX 57035 and Baldwin B7165, plus NAPA Gold 7035, Stens 120-485 and Briggs & Stratton 492932S. It is a short spin-on oil filter for Kawasaki FR, FS and many FX series small engines used in residential and commercial lawn equipment. Any filter sharing its 3/4"-16 thread, 3 in outside diameter and 2 1/4 in height is a valid replacement.
What Is the Kawasaki 49065-0721 Oil Filter?
The Kawasaki 49065-0721 is the OEM spin-on oil filter for a wide range of Kawasaki small engines. You will find it on riding mowers, zero-turn mowers, and commercial lawn equipment powered by Kawasaki's FR, FS, and FX engine families.
It replaced the older 49065-7007 part number, and Kawasaki has since released the 49065-0736 as the current superseding number. Kawasaki's own supersession list shows the 49065-0736 replacing 49065-7007, 49065-7002, 49065-2076, 49065-2077 and 49065-0721.
All of those numbers are one filter. Buying any of them gets you the same part in a different generation of packaging.
What Equipment Uses the Kawasaki 49065-0721?
The 49065-0721 fits Kawasaki's most widely used commercial and residential small engine lines. Common applications include:
- FR651V, FR691V, FR730V: residential zero-turn mowers and riding tractors
- FB460V, FC420V, FC540V, FD501D, FD590V: older single and twin cylinder engines
- FX481V, FX541V, FX600V, FX651V, FX691V, FX730V: commercial V-twins found in Scag, Ferris, Husqvarna, Toro and Exmark equipment
That engine list comes from Kawasaki's own application data for the superseding 49065-0736, which also covers John Deere, Kohler, Tecumseh and Briggs & Stratton engines using the same filter.
The engine model is stamped on the engine block or on a label on the valve cover. Always verify by engine model number, not equipment model number.
Careful with FX engines. Some FX series engines take the taller 49065-0724 instead, which is a different filter entirely. If your engine is an FX, measure before you buy.
Kawasaki 49065-0721 Specifications
These are the physical specs that define compatibility across all cross-referenced brands.
| Kawasaki 49065-0721 | What the spec sheets say |
|---|---|
| Thread size | 3/4"-16 |
| Outside diameter | 3 in |
| Overall height | 2 1/4 in |
| Anti-drain valve | Yes |
| Pressure relief valve | 7 to 9 PSI |
| Micron rating | 28 micron |
The 3/4"-16 thread is the same standard used on many automotive spin-on filters, which is why automotive brands cross reference to this Kawasaki number at all.
The thread is also the trap. The taller 49065-0724 uses the same 3/4"-16 thread, so it will spin on and seal, and it is still the wrong filter. Height and outside diameter are what separate the two.

| Brand | Part Number | Notes |

| Kawasaki OEM (older) | 49065-7007, 49065-7002, 49065-2076, 49065-2077 | All superseded by the 0736 |

Oregon, Stens and Briggs & Stratton are outdoor power equipment brands that stock this cross reference for small engine applications. If you buy from a dealer rather than an auto parts store, these are the numbers on the shelf.
The route to the aftermarket numbers. Stens 120-485 covers the whole Kawasaki 49065-0721 family and also replaces Briggs & Stratton 492932S. Briggs publishes FRAM PH8170, WIX 57035 and Baldwin B7165 as the crosses for the 492932S, which is how the automotive numbers connect to this filter.
Are the 49065-0721, 49065-7007, and 49065-0736 the Same Filter?
Yes. This is the most common point of confusion with this filter, and the answer is simpler than the internet makes it look.
Kawasaki updates part numbers when it revises packaging, switches suppliers or makes minor production changes. The 49065-7007 came first, the 49065-0721 replaced it, and the 49065-0736 supersedes both along with the 49065-7002, 49065-2076 and 49065-2077.
One filter, six numbers. When you order the 49065-0736 today you are getting the current production version of the same part.
The filter that is genuinely different is the taller 49065-0724 and 49065-7010, which crosses to FRAM PH4967 and WIX 51394 instead. Same thread, different body.
Can I Use a FRAM or WIX Filter Instead of the Kawasaki OEM?
Yes. The FRAM PH8170, WIX 57035 and Baldwin B7165 are all verified cross references. They fit the same 3/4"-16 thread, seal against the same gasket surface, and match the OEM filter's 3 in outside diameter and 2 1/4 in height.
The OEM filter is a 28 micron element with a 7 to 9 PSI pressure relief valve and an anti-drain valve. Aftermarket filters in this group are built to the same envelope, so the choice comes down to media grade and price rather than fit.
Kawasaki's warranty is not voided by using a quality aftermarket filter. The Magnuson-Moss Warranty Act protects your right to use aftermarket parts without losing coverage, as long as the replacement is not defective and does not cause damage.
Pro tip: For commercial equipment running all day in dust, the Baldwin B7165 is the heavy-duty option in this group. For residential mowing a few hours per week, the OEM filter or the FRAM PH8170 is more than sufficient.
How Often Should You Change the Kawasaki 49065-0721?
Kawasaki recommends an oil and filter change at 50 hours for the initial break-in on new engines. After break-in, the standard interval is every 100 hours or once per season, whichever comes first.
Under severe conditions such as continuous commercial use, heavy dust, or high ambient temperatures, Kawasaki recommends shortening the interval to every 50 hours.
How to Install the Kawasaki 49065-0721 and Its Replacements
- Run the engine for a few minutes to warm the oil, then shut it off and wait 5 minutes.
- Place a drain pan under the filter.
- Remove the old filter by turning it counterclockwise. Expect some oil to spill.
- Wipe the filter mounting base clean with a lint-free cloth.
- Lightly coat the rubber gasket on the new filter with fresh oil.
- Thread the new filter on by hand until the gasket contacts the base.
- Tighten an additional three-quarters of a turn. Do not use a wrench for installation.
- Start the engine and check for leaks around the gasket. Recheck the oil level after running for one minute.
FAQ
What does the Kawasaki 49065-0721 cross reference to? The FRAM PH8170, WIX 57035, Baldwin B7165 and NAPA Gold 7035 are the confirmed cross references. Stens 120-485 and Briggs & Stratton 492932S are the equivalent numbers at outdoor power equipment dealers.
Is the Kawasaki 49065-0721 the same as the 49065-7007? Yes. They are the same filter under two numbers. Kawasaki's supersession list puts the 49065-7007, 49065-7002, 49065-2076, 49065-2077 and 49065-0721 all under the current 49065-0736, and both cross to WIX 57035 and NAPA Gold 7035.
What is the newest Kawasaki part number for this filter? The 49065-0736 is the current OEM number. It supersedes the 49065-0721, 49065-7007, 49065-7002, 49065-2076 and 49065-2077. All of them fit the same FR, FS and FX series applications this filter covers.
What thread size does the Kawasaki 49065-0721 use? The 49065-0721 uses a standard 3/4"-16 thread. That thread is shared with the taller 49065-0724, so thread alone does not confirm fit. Check that the filter is 3 in across and 2 1/4 in tall as well.
Can I use a WIX 57035 instead of the 49065-0721? Yes. The WIX 57035 is the correct cross reference for the 49065-0721 and for every number in its supersession family. The WIX number to avoid on this engine is the 51394, which fits the taller 49065-0724 and 49065-7010 filter instead.
Before you order anything, measure the filter you are taking off. If it is roughly 3 in across and 2 1/4 in tall on a 3/4"-16 thread, you are in the right family and the FRAM PH8170 or WIX 57035 will fit. If it is taller and narrower, you have the 49065-0724 filter and you need the PH4967 family instead.
The current OEM number is the 49065-0736. Stick to the 100 hour change interval and the engine will stay clean season after season.
