The K&N 77-3077KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some GMC Sierra 2500/3500 HD and Chevrolet Silverado 2500/3500HD 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 77-3077KP air intake comes with a black rubber 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 turbo inlet 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 sensors. 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 some Allen 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.

Customer Feedback


Installed on my 2014 GMC 1500 4x4 Sierra Crew Cab. I'm no mechanic so the install took me about an hour, and was fairly easy. I already have a Borla Exhaust on the truck, but still noticed a much deeper sound. Haven't noticed a difference in mpg plus or minus, but could just be the way I drive.

Used this and still using on 2005 GMC Sierra 5.3l base model. Increased mileage 2.1 normal driving, 1.1 mile heavy foot driving. Also engine sounded smoother at idle and smoother acceleration. Have used with Ford ,Nissan and Isuzu, all with a same effect.
Ron Mcneal, Lewisville, Texas
Easy install. Roughly 45 minutes with simple tools. Day after install reset my fuel economy and took my 2013 GMC 2500 HD Duramax for a 3 hour trip noticeably throttle response (don't have a dyno so can't claim horsepower) AND gained 2.5 MPG. That's right. 2.5 more miles to the gallon. The truck only has 45,000 miles on it. Fuel savings will pay itself off in no time. Great product, definitely would recommend it to anyone.
