RFX Foam Air Filter FXAF7000155NO - Sherco 250 / 300 / 450 SE-R / SEF-R 2014-2024

Product Description

The RFX Air Filter provides high-capacity intake filtration and smooth airflow for Sherco two-stroke and four-stroke enduro motorcycles. Manufactured by Multi Air, this twin-layer foam air filter lets your engine breathe cleanly while maintaining a protective barrier against airborne roost, sand, and fine trail dust.

Engineered with breathable twin-layered foam, the coarse outer layer captures larger mud, grit, and roost, while the dense inner layer catches micro-particulates before they can enter the intake boot. Built using flame-retardant nonflammable foam suited for four-stroke applications, it provides an exact airbox fitment developed through Multi Air's 30-plus years of off-road competition experience.

Frequently Asked Questions

Q: Does this RFX air filter come pre-oiled or dry?
A: This filter (MPN FXAF7000155NO) is supplied dry (un-oiled) and must be properly treated with foam air filter oil prior to installation.

Q: Can this filter be used on both 2-stroke and 4-stroke Sherco models?
A: Yes, it is built to the exact airbox dimensions shared across the listed 2-stroke SE-R and 4-stroke SEF-R Factory platforms.

Q: Why is nonflammable foam used on 4-stroke models?
A: Four-stroke powerplants can backfire through the intake tract. Nonflammable foam helps prevent backfire sparks from igniting the filter media or oil.

Expert Pro-Tip: When oiling a dry foam air filter, work foam filter oil thoroughly through both foam layers until the color is completely uniform across the entire surface. Gently squeeze out any excess oil without twisting or wringing the seams, and allow the carrier solvent to evaporate for 15 minutes before seating the filter cage into the Sherco airbox.
