The K&N 77-3086KTK 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 77-3086KTK 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. 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.

K&N 77-3086KTK Air Intake Product Reviews

Wednesday, August 23, 2017 - Part 77-3086KTK
The install was completed without any issues and took about one hour. The results actually show and increase in gas mileage of about 1-2 miles per gallon around town. Although not dyno tested, I can feel the extra HP when I get into the throttle. It also has a deeper sound which sounds great. Headed for Colorado next month so we will see what the over the road results prove to be. This is the second air intake system I have purchased. I am a believer and would highly recommend this product.

Worth the money. Throttle response much better and love the sound. Install pretty easy.Took about 30-40 minutes. Gained around 1 mpg on the fuel consumption as well.

Purchased this intake system for my 2015 GMC 2500HD. The engine light came on right away. After a few miles the computer adjusted to the new system, but the engine light stayed on. K&N techs very helpful, they recommended I drive it some more. 80 miles later the light went out. It feels like a little more power than advertised, and sounds great. Not loud during normal driving. Also looks like a little increase in mileage, hope so, I tow a 5th wheel. K&N has a dry filter that works with this intake if you don't like the oiled one. Overall, very nice product. Stayed with K&N because I'm used to their products.

Gained a growl, a slight (1-2 mpg) while pulling my camper, and noticable power upon acceleration at all times on my 2015 Chevy 2500 HD. Very simple install. If you're looking at a cold air intake, pull the trigger. It's not a huge difference, but is noticeable and true to the description provided by K&N.

I installed the intake in about an hour, the directions were great. Took my truck for a test drive and couldn't believe the change in the sound. Now I need an exhaust system.
