2011 and 2012 GMC Sierra 2500HD and 3500HD and 2011 and 2012 Chevy Silverado 2500HD and 3500HD 6.0 liter gas engines are some of the more powerful available on the market today. Adequate airflow is the key to the performance of these large engines. On the flip side of the coin, every driver knows how important filtration is to a vehicle’s operation and engine longevity. To balance high airflow and high filtration efficiency, K&N has developed the 77-3076KTK performance air intake system for 2011 and 2012 GMC Sierra and Chevy Silverado 2500HD and 3500HD trucks with 6.0 liter engines.
Built for performance and show, the K&N 77-3076KTK High-Flow Performance Air Intake is a free-flowing mandrel-bent aluminum tube induction system designed to fit easily into 2011 and 2012 GMC Sierra and Chevy Silverado 2500 and 3500 6.0 liter models. This air intake system comes with a K&N high flow air filter, a custom designed heat shield and lid to help keep engine heat away and all the necessary components needed for installation. The system has fittings for the crankcase breather hose and a mass air sensor adapter custom designed to perform with the factory’s electronics. On top of utilizing the highest quality, vehicle-specific components, the 77-3076KTK is also backed by K&N’s Million Mile Limited Warranty, giving owners the peace of mind to know that their investment is safe.
K&N air intake systems are a simple bolt-on installation that replaces the vehicle’s stock restrictive factory air filter and air intake setup. The 77-3076KTK is also designed to dramatically reduce intake restriction while it straightens air flow. This allows your vehicle’s engine to inhale a larger amount of air than the OEM air filter assembly. Less restriction means more usable horsepower, torque and acceleration throughout the engine’s RPM range. When dyno tested, the air intake system showed an estimated performance increase of 10 horsepower at 5033rpm and 10 lb-ft of torque at 4736rpm on a 2012 Chevrolet 2500HD pickup with a 6.0 liter V8 engine. The air intake system also allows for an increase in engine sound offering a deeper throatier roar when you step on the gas.
The performance air filter, part RF-1042XD, used on the 77-3076KTK intake is also washable and reusable. Being washable and reusable, the RF-1042XD air filter can go up to100,000 miles depending on driving conditions and it is easily cleaned using the K&N recharger kit meaning you can have more time on the road and less time changing expensive disposable air filters in your garage. The filter is designed with a woven oiled cotton media to ensure excellent filtration efficiency for engine protection.
The 77-3076KTK comes with step-by-step install instructions for easy installation. Including pictures of each component and area of the engine bay as parts get removed and installed. Average installation time runs less than 90 minutes depending on the installer’s skill level.
