Twin Air Standard Air Filter 151009 — Kawasaki KX80 / KX85 / KX100 / KX112 1991-2025

Product Description

Keep your mini racer running at peak performance while ensuring bulletproof engine protection with the Twin Air Standard Air Filter. Renowned worldwide as the ultimate choice for motocross champions, this air filter features a breakthrough dual-bonded foam design that filters out even the smallest micro-particles of dust and sand. By replacing your stock filter with Twin Air technology, you protect your top end from premature wear without sacrificing precious airflow or throttle response.

The secret behind the industry-leading filtration of the 151009 filter is its fused layers of open-pore foam and fine inner foam. Unlike multi-layer systems that trap air between sheets of material, Twin Air's flow-bench-proven lamination process allows maximum air volume to pass cleanly into the intake tract. Additionally, these filters are engineered to be slightly smaller than OEM options, increasing the vital dead air space inside the airbox for optimized breathing while making filter swaps fast and effortless at the track.

Top Features: Twin Air Standard Air Filter

• Dual-Bonded Foam Layering: Fuses coarse outer foam and fine inner foam together to stop abrasive debris while maximizing intake velocity.
• Flat Foam Sealing Ring: Features an extra-thick, heavyweight greaseless sealing ring that guarantees a flush, airtight lock against your airbox.
• Optimized Sizing: Tailored slightly more compact than original equipment to significantly facilitate installation and optimize airbox circulation.
• Fully Washable and Reusable: Built tough to withstand aggressive washing solvent cycles and repeated re-oiling without crumbling or separating.

Frequently Asked Questions

Q: Does this filter come pre-oiled from the factory?
A: No, this is the standard Twin Air filter version and comes dry out of the package. You must thoroughly saturate it with a high-quality foam filter oil and allow it to tack up before installing it on your machine.

Q: Can I wash this filter with gasoline or harsh solvents?
A: We highly recommend against using raw gasoline, as it can degrade the premium glue bonds over time. Instead, utilize specialized foam filter cleaners or kerosene followed by warm, soapy water to preserve the life of the dual-bonded foam layers.

Expert Pro-Tip: When servicing your KX mini filter, never wring out or twist the foam like a towel to remove excess oil or water. Twisting tears the seams and ruins the cell structure. Instead, compress the filter firmly in your palms to squeeze the excess out. Also, ensure you wipe out the entire inside of your dirty airbox and check that the filter cage pins snap fully into place to prevent nasty leaks.
