The K&N 77-3090KTK Air Intake fits some Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, and GMC Sierra 3500 HD models. See vehicle applications link for details.
The K&N 77-3090KTK high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit specific Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/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. In addition to more power, this air intake system improves engine sound with more aggressive and deeper acoustics during acceleration. Includes a chrome topped K&N high-flow air filter and a heat shield that installs into the original 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 textured black powder-coated finish that's made to last and it accommodates the factory mass air sensor and 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 couple of screwdrivers, a 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 installed this K&N air intake system a few weeks ago on my 2016 GMC Siera 2500HD and I love it. It took me about 1/2hour to install ( thanks to you tube ) and the change was immediate. I get about 2 miles per gallon more but the response is what I like. I can hear the air being sucked in and it just sounds deeper when I step on it.
