The K&N 77-3037KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Hummer H2 models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-3037KP air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive chrome-like finish that's made to last and it accommodates the factory mass air sensor and a replacement silicone crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, ratchet set and several wrenches. Some K&N 77 series air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

I just had the performance chip installed on my 2003 H2 Hummer where I'm saving a lot of gas, now I just installed the 57-3037. I'm just worried about the fan almost touching the intake arm. It's a tight fit the space between the fan and the intake is approx. 1 in.

I am trusting that these filters are equal in capability to Amsoil filters since K&N is a name that I would also trust. What I really like is the ability to easily change these filters with a socket wrench. This makes changing filters far more easy and faster than any and all other filter designs. I really like these filters! I use them in a Hummer H2 and a Ford SHO.

Ordering was simple, delivery was quick, and installation was smooth. I hate replacing air filters every 10000 miles, so this is an easy way to keep the car running. Just put 50000 miles on the K&N filter on my Hummer H3. Seems strange that in the 1950's we had oil bath filters, then came wonderful cotton, and now back to oiled filters........ Similar to 1950 blacked wheels, then chrome, and now back to black. What is next?
