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, March 20, 2019 - Part 77-3086KTK
I PURCHASED THIS 77-3086 KTK K&N PERFORMANCE AIR INTAKE SYSTEM, FOR MY 2015 GMC HD W/ A 6.0, GASOLINE ENGINE. ALONG WITH THE INTAKE SYSTEM, I INSTALLED A 200-606 - AIRAID THROTTLE BODY SPACER. I TOOK A 300 MILE TRIP LAST WEEKEND. MY FUEL MILE INCREASED APPROXIMATELY 1 GPM, OVER THE 300 MILE TRIP. THE MILEAGE MAY GET BETTER IN TIME, I JUST COULD NOT “KEEP MY FOOT OUT OF IT”, ON THIS TRIP. THE ACCELERATION WAS A NOTICEABLE INCREASE. I DIDN’T HEAR A WHISTLE SOUND, THANK GOODNESS, IT DEFINITELY SOUNDS BEEFY WITH THE THROTTLE BODY SPACER INSTALLED, I DID HAVE TO TRIM ONE CORNER OF EACH FAN BLADE, LESS THAN 1/2”, FOR CLEARANCE, OF THE INTAKE SYSTEM. I CHOOSE TO PURCHASE MY 77-3086 KTK K&N PERFORMANCE AIR INTAKE SYSTEM, DIRECTLY FROM K&N, THE PRICE WAS COMPARABLE WITH EVERY OTHER PLACE I SHOPPED. THERE MAY BE CHEAPER BRANDS, THIS I HAVE A K&N AIR SYSTEM.

Perfect Fit. Easy to install (40 minutes). Sounds great. Seems to have more power on big hills pulling my 33 foot RV. Very pleased.

2015 2500 Silverado 4x4 with a 6.0. Quick shipment high quality parts and hardware. Great instructions and easy to install took about 30 min. With intake and exhaust truck sounds great and seems to have better throttle response. Haven’t checked to see if gas mileage is and better yet but seems to have more torque when pulling trailer. Thanks K&N, Will purchase for new vehicles also.
