Stens 120-634 Oil Filter Compatible With/Replacement For Kawasaki FH381-721V, FH601-770D, FJ180V and FX751-1000V; for 14-19 HP engines 49065-0724, 49065-2057 Lawn Mowers

What It Is

The Stens 120-634 is an aftermarket oil filter designed for Kawasaki-powered lawn mowers, including zero-turn mowers, tractors, and commercial walk-behinds. It’s a direct replacement for OEM filters on 14–19 HP engines in the FH, FJ, and FX series, providing essential engine oil filtration to extend engine life.

Fitment & Compatibility

Check your engine model—this filter fits Kawasaki FH381V through FX1000V, plus FJ180V and FH601-770D. Also replaces OEM part numbers 49065-0724 and 49065-2057. Measure the filter: 3.5" tall, 2.75" outer diameter, and 3/4-16 thread. It works on most Kawasaki-powered mowers with those engines, but verify your mower’s engine plate or manual—brands like John Deere, Husqvarna, and Toro use these engines, but deck size doesn’t matter. If your mower uses a different thread or shorter filter, this won’t fit.

Key Things to Know

• Quality: Stens is a reputable aftermarket brand; this filter meets or exceeds OEM specs (micron rating, burst strength). Expect similar performance to Kawasaki’s own filter.
• Installation: Simple hand-tighten job—apply a thin oil film to the gasket, spin on until snug, then 1/2 to 3/4 turn more. No special tools needed.
• Common gotcha: Don’t overtighten—it can warp the gasket or damage the filter housing. Check for leaks after first start.
• Price vs OEM: At ~$14, it’s typically 30–50% cheaper than Kawasaki’s OEM filter, with nearly identical ratings.

Should You Buy It

Yes, if you own a Kawasaki FH/FJ/FX engine mower and want a reliable, budget-friendly alternative to OEM. It’s a solid choice for DIY maintenance, with strong user ratings and proven compatibility. Avoid if you prefer OEM-only parts or have a non-Kawasaki engine.
