K&N 57-3077 performance air intake system for the Chevy Silverado or GMC Sierra Duramax

The 57-3077 2011-2014 Chevy Silverado or GMC Sierra Duramax intake includes a performance designed intake tube & oversized air filter to help streamline airflow into the turbocharger

In the 1990s and early 2000s, GM ran an advertising campaign dubbed “Like a Rock,” promoting the durability of their trucks and how owners of Chevrolet trucks were strong and independent. The campaign proved to be one of the most successful for GM and while that campaign ended in the early 2000s, the legacy of toughness has continued long after the last advertisement aired. The 2011, 2012, 2013 and 2014 Chevrolet Silverado HD and GMC Sierra HD Duramax diesel pickups epitomize the durability of GM trucks with fully-boxed frames, Allison transmissions, improved suspension, massive towing/hauling capacity and the Duramax 6.6L diesel engine with mountains of torque.

2011, 2012, 2013 and 2014 Chevrolet Silverado 2500 HD and 3500 as well as GMC Sierra 2500 HD & 3500 Duramax diesel pickups epitomize the durability of GM trucks

Auto manufacturers usually sacrifice airflow in order to keep under hood noise to a minimum. This is what makes aftermarket air intakes, like those from K&N filters, so effective. However, in many U.S. states diesel-powered vehicles have to meet emissions standards similar to gasoline-powered cars and trucks. Thankfully, the K&N 57-3077 performance air intake system for the Chevrolet and GMC truck models listed below has received an exemption from the California Air Resources Board (CARB), # D-269-49, making this air intake system 50-state street legal.

The 57-3077 2011, 2012, 2013 and 2014 Chevrolet Silverado HD and GMC Sierra HD Duramax diesel performance intake is an easy-to-install performance upgrade, comes with all components necessary for installation, and replaces the entire factory intake system from the turbocharger forwards. A precision-engineered, high-density polyethylene intake tube replaces the corrugated factory tube, helping to reduce turbulence and streamline airflow into the turbocharger. The K&N air intake tube comes with provisions for one or both intake sensors, depending on the factory setup.

On the dyno on a 2012 Chevrolet Silverado 2500HD 6.6 liter turbo diesel equipped with the 57-3077 K&N air intake produced an estimated additional 19.3 horsepower and 44.6 lb-ft of torque

A massive K&N reusable air filter, number RC-5179, is fitted to the end of the K&N air intake tube replacing the factory air box and restrictive disposable air filter. This diesel specific oversized conical K&N air filter is designed to provide a large surface area, provide high airflow and ensure exceptional engine protection. Diesel intake air filter RC-5179 has been tested in house and shown to be exceptionally efficient with an overall filtration efficiency rating of 99.49%. This air filter is also washable and reusable, capable of going up to 100,000 miles between cleanings, depending on driving conditions. An application specific air filter heat shield with lid shrouds the air filter from radiant heat under the hood, and the filter is placed near the factory cold air fender well inlet to draw cooler air from outside the truck.

These big turbo diesel engines require a lot of air, and will thank you for any modifications that help to minimize restriction in the airflow pathway by rewarding you with more power. This is exactly the case with the K&N 57-3077 Duramax diesel performance air intake system. On the dyno on a 2012 Chevrolet Silverado 2500HD 6.6 liter turbo diesel equipped with the 57-3077 K&N air intake produced an estimated additional 19.3 horsepower at 2420 rpm and 44.6 pound-feet of torque at 2300 rpm over the factory air intake system. Those are massive power gains, to the wheels, showing how positively these big diesel engines react to less restriction from a K&N performance diesel air intake.

K&N intake systems are designed to go the distance, just like the mighty Duramax diesel engine, and are backed by a 10-year/million mile limited warranty. K&N also guarantees an increase in horsepower and torque on the Duramax models listed below with the installation of K&N air intake 57-3077.
