Product Details

K&N Universal X-Stream Clamp-On Air Filter

If you’re building a custom intake or replacing a tired cone, the K&N Universal X-Stream Clamp-On Air Filter lets your vehicle breathe. Enjoy crisper throttle and smooth airflow while keeping debris out. Pliable rubber flanges flex and stretch up to 1/16 inch to slide over custom pipes and soak up vibration, delivering a snug fit. A heavy-duty zinc-plated gear clamp locks it down for an airtight connection that won’t creep under heat, bumps, or boost.

Set it up your way: choose the classic pre-oiled red gauze for trusted K&N flow and long service, or the dry synthetic blue for quick, no-oil cleanups. Round, oval, and tapered cone shapes let you squeeze maximum filter area into tight bays and odd angles without starving your setup. Whether you’re routing around a turbo, tucking behind a headlight, or upgrading, this universal clamp-on filter makes the job easy and effective.
