Hipa Inner & Outer Air Filter for Kawasaki 11013-7044 FX850V FX730V FX691V FX801V FX751V FX1000V FH680V 11013-7045 25 083 01-S AF25551 M131802

What It Is

This is a replacement Inner and Outer air filter set for Kawasaki FX, FH, and FS series V-twin engines commonly found on zero-turn mowers, riding mowers, and commercial lawn equipment. The two-stage filtration (pre-filter outer + fine inner) protects the engine from dust and debris.

Fitment & Compatibility

Check your engine model number – this fits Kawasaki FX730V, FX751V, FX801V, FX850V, FX921V, FX1000V, FH680V, FS541V, and FS600V. The OEM cross-references are Kawasaki 11013-7044, 11013-7045; also matches 25 083 01-S, AF25551, M131802.
Not model-specific – verify your engine’s exact displacement (e.g., 726cc vs 852cc) as some FX series share the same filter but not all. Measure your current filter: outer ~6.2” x 3.5”, inner ~4.5” x 3.0”.
Physical fit – the Hipa set is a drop-in replacement for OEM; no modifications needed if your engine uses the two-filter canister style.

Key Things to Know

• Quality vs OEM – Hipa uses dense foam pre-filter and pleated paper inner; slightly less robust than Kawasaki OEM but 90%+ filtration efficiency for residential use.
• Installation – simple: remove cover, pull old filters, clean housing with damp cloth, insert new inner then outer, secure cover. No tools required.
• Common gotcha – don’t over-tighten the cover knob; hand-tight only to avoid cracking the plastic housing.
• Change interval – replace every 100 hours or annually; more often if mowing in dusty/dry conditions. Inspect inner filter for tears before reusing.

Should You Buy It

If you need a reliable, affordable replacement for a Kawasaki FX/FH engine on a residential or light-commercial mower, this set delivers solid performance at roughly half the OEM price. Avoid if you operate in extreme dust (e.g., farm/construction) – stick with genuine Kawasaki for maximum protection.
