The K&N 77-3021KP Air Intake fits some Chevrolet Silverado 1500, Chevrolet Silverado 2500, Chevrolet Silverado 3500, and GMC Sierra 1500 models. See vehicle applications link for details.
The K&N 77-3021KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some GMC Sierra 1500 and Chevrolet Silverado 1500 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 77-3021KP 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. 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 an Allen wrench. 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.

K&N 77-3021KP Air Intake Product Reviews

Monday, August 21, 2017 - Part 77-3021KP
This cold air intake doesn't only look beautiful under the hood, it provide more HP to my truck and improved the throttle response as well. My engine also sounds different; more of a deep more power sound. And the best part is that it was easy to install and provided a great step by step instruction manual specific to my engine. I can absolutely say I feel the difference in performance and I'm extremely happy with the product.
