Product Details
K&N Universal X-Stream Clamp-On Air Filter
Build a cleaner, freer-breathing intake without reinventing your setup. The K&N Universal X-Stream clamp-on filter is a smart upgrade when you’re fabricating an intake, refreshing a worn cone, or making room in a tight bay. It mounts easily, seals tight, and lets your vehicle pull in air with less hassle.
Pliable rubber flanges flex and stretch up to 1/16" over custom tubing, soaking up vibration and making imperfect pipe sizes a non-issue. Choose your media—classic pre-oiled red gauze for strong airflow with proven filtration, or low-maintenance dry synthetic blue when you want quick service without oil. With round, oval, and tapered-cone options, you can snake the filter into cramped spaces and still keep the element where it feeds best. A heavy-duty, zinc-plated gear clamp delivers a secure, tool-assisted connection for an airtight seal that stays put through heat cycles, bumps, and spirited driving.
