Product Details

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

Build your intake the right way. This universal clamp-on filter lets your vehicle breathe easier, improving airflow for crisper throttle response and a cleaner, more confident pull—without complicated brackets. It’s a smart pick for custom intakes, swaps, turbo setups, or anytime you need proven K&N filtration in a tight spot.

Pliable rubber flanges flex to slip over custom pipes—stretching up to 1/16 inch—to absorb vibration and keep the filter planted. A heavy-duty zinc-plated gear clamp locks down an airtight seal, so you avoid unmetered air and keep sensors happy mile after mile.

Pick the media that fits your routine: the classic pre-oiled red cotton gauze for maximum flow and that unmistakable intake sound, or the dry synthetic blue for quick, no-mess maintenance. With round, oval, and tapered cone geometries, you can snake around strut towers and radiators for the perfect fit. Bolt it on and let it breathe.
