Flame-retardant foam prevents backfire sparks from igniting the filter media or filter oil.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: How often should I inspect and clean this filter?\u003c\/b\u003e\u003cbr\u003eA: Inspect your filter after every ride. In dry or heavy roost conditions, clean and re-oil or replace the filter after each ride to maintain proper engine protection.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e When installing a fresh pre-oiled air filter, wipe the airbox sealing surface clean with a lint-free shop towel first. Apply a thin bead of waterproof rim grease along the sealing edge of the filter base to create an airtight seal that prevents micro-dust from creeping past the airbox mating surface during long, dusty motos.\u003c\/p\u003e\n\u003ch3\u003eRecommended Pairings:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/honda-crf250r-performance-parts-kits-and-accessories-moto-house-mx\"\u003eHonda CRF250R Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/honda-crf450r-performance-upgrades-engine-mods-and-accessories-moto-house-mx\"\u003eHonda CRF450R Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003eAir Filter Cleaners \u0026amp; Maintenance Chemicals\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
