Product Description

The K&N RP-5103 is a large oval universal air filter distinguished by its K&N-embossed carbon fiber top and base, giving it added strength alongside a distinctive, lightweight, glass-like finish. Its 12 in. x 6 in. base and 7 in. height make it suited to performance intake setups with generous underhood clearance, and it's the confirmed replacement filter for K&N's 57-3037 performance intake kit used on the 2003-2007 Hummer H2.

Built from premium oiled cotton gauze, the RP-5103 is engineered for high airflow and strong filtration, helping protect the engine from contaminants while supporting a boost in horsepower and acceleration. Its pliable rubber flange absorbs vibration for a secure clamp-on fit and can stretch slightly to accommodate minor variations in intake neck sizing.

This filter is a strong fit for Hummer H2 owners maintaining an existing K&N 57-3037 intake system, as well as builders working on other custom or performance intake setups who need a large-capacity oval filter with a distinctive carbon fiber finish. Since it's cataloged as a universal part, confirm your flange diameter and available clearance match before ordering if you're not replacing filtration on a factory-matched K&N kit.
