K&N HP-2004 is a heavy‑duty spin‑on oil filter engineered to provide long‑service‑interval protection, high flow rates and quick wrench‑off removal for a wide range of cars, trucks and commercial vehicles.

This premium K&N oil filter combines pleated synthetic‑blend media, a reinforced canister and a welded one‑inch hex nut so it holds up to extended service intervals while staying easy to change.

How does the HP‑2004 protect my engine during extended intervals?
