Kawasaki OEM Inner & Outer Air Filter Combo for FD/FX Engines — 11013-7044 & 11013-7045, Factory Fit & Protection

Genuine Kawasaki inner and outer air filter combo (part numbers 11013-7044 & 11013-7045) designed to fit specific FD and FX series Kawasaki engines for reliable intake protection.

This OEM air filter set includes one inner and one outer filter engineered by Kawasaki to meet factory specifications for select FD731V, FX651V, FX691V, FX730V, FX751V, FX801V, FX850V, FX921V and FXT00V engines. These filters are made to fit precise model and serial ranges, so it’s important to confirm compatibility with your engine’s model, type and serial number before purchasing. Using the correct OEM filters helps preserve engine performance by maintaining proper airflow while trapping dust and debris.

Will this filter combo fit my specific Kawasaki engine model?

Compatibility is model- and serial-number dependent. The combo covers many FD and FX engine variants, but not every production sub-spec of those models.

• Check part numbers 11013-7044 (inner) and 11013-7045 (outer) against your engine documentation.
• Verify your engine model (FD731V, FX651V, FX691V, FX730V, FX751V, FX801V, FX850V, FX921V, FXT00V) and serial range.
• Contact your dealer or consult Kawasaki parts diagrams for exact fitment confirmation.

How do these OEM filters affect engine performance and longevity?

Factory-designed filters balance airflow with contaminant capture to protect internal engine parts. Proper filtration reduces abrasive particles entering the engine, which helps maintain compression and component life.

• Inner and outer layers work together to trap both large and fine particulates.
• Maintains designed airflow characteristics for intended power and efficiency.
• Reduces wear on cylinders, pistons and valves compared with degraded or incorrect filters.

How should I install and maintain the inner and outer filters?

Installation is straightforward when following your engine’s service manual. Replace filters at manufacturer-recommended intervals or sooner in dusty conditions to ensure ongoing protection.

• Remove old filters, inspect the airbox for debris, and wipe clean before fitting new filters.
• Install the outer filter first (if applicable), then seat the inner filter so both form a proper seal.
• Check seals and clamps; replace damaged gaskets and fasteners to prevent air leaks.

What are the benefits of choosing genuine Kawasaki parts over aftermarket alternatives?

Genuine Kawasaki filters are engineered to match factory tolerances, materials and filtration media. That fit-and-function alignment reduces the risk of improper sealing or altered airflow that can arise with non-OEM parts.

• Exact compatibility with Kawasaki airbox geometry and mounting points.
• Filtration media selected for the engine’s original design parameters.
• Backed by Kawasaki part numbering and dealer support for replacements.

Who is this for: This inner and outer air filter combo is intended for owners and technicians maintaining compatible Kawasaki FD and FX series small engines who want OEM fitment and performance. It’s a good choice for routine service, seasonal rebuilds, and heavy-use applications where preserving engine reliability matters. Always verify your engine’s model, type and serial number to ensure these filters are the correct match before ordering.
