The K&N 77-3047KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some GMC Sierra 2500HD/3500 and Chevrolet Silverado 2500 HD/35000 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 77-3047KP 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 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 the air filter accommodates the filter restriction gauge. The oversized tapered cylinder 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 bought a new 2014 GMC Terrain and I did what I've done with the last eight new vehicles I've purchased I replaced the original factory air filter with a K&N filter. In every case, I've seen an improvement in fuel economy and an increase in horsepower. What's not to like about that?!

Great product and my 2009 GMC Sierra 1500 sounds great, faster throttle response and looks great under the hood. It took a few hours to install and easy to work with, minor drilling but over all easy to install for someone that doesn't mind getting their hands dirty. Highly recommended.

I purchased this for my 2012 GMC Acadia Denali with the 3.6 engine. Mileage improved a small amount and acceleration was a bit more crisp from a dead stop but more noticeable when accelerating while driving where speeds were around 40 MPH. Very noticeable when accelerating onto a freeway.
