General Motors designed its line of HD full-size pickups, which includes the Chevy Silverado HD and GMC Sierra HD, to provide high towing and payload capacities beyond that of a regular duty pickup. While the 2500 and 3500 HD trucks have proved themselves as a solid work-horse, they’ve also become very popular with the custom truck crowd. Lifted and lowered Duramax diesel powered Silverados and Sierras can be seen storming the streets with a commanding presence. Here to help increase the horsepower, torque, and boldness of these already menacing trucks is the new Blackhawk Air Induction System, 71-3066, from K&N.

The 71-3066 Blackhawk Air Induction System is expert-engineered and guaranteed to increase horsepower and torque. It replaces the restrictive factory system with a free-flowing, mandrel bent aluminum air intake tube to help minimize restriction, straighten, and increase airflow to the engine. The mandrel bent aluminum intake tube is finished in a durable flat black powdercoat for a stealth look under the hood. K&N 71-3066 incorporates a heat shield which helps guard air entering the engine from ambient heat.

For that true blacked out look K&N designed a new line of all black synthetic Dryflow air filters. Air induction system, part number 71-3066, includes K&N’s RU-5177HBK conical Dyflow air filter fitted to the inlet of the air induction system. K&N Dryflow filters provide excellent airflow rates as well as outstanding filtration efficiency. RU-5177HBK is washable and reusable and can go up to 100,000 miles between cleanings, depending on driving conditions. Use of Synthetic Air Filter cleaner, number 99-0624, is recommended when it comes time to clean RU-5177HBK. This Dryflow air filter does not need to be oiled.

Blackhawk Air Induction Systems are designed to perform as good as they look. The K&N 71-3066 air induction system puts down impressive performance gains in horsepower and torque. On the dyno, when installed on a 2007 Chevrolet Silverado 2500 HD 6.6 liter V8 diesel, the 71-3066 air induction system produced an estimated additional 12.53 horsepower at 2638 rpm and an incredible 27.67 pound-feet of torque at 2298 rpm.
