K&N Air Intake Adds Power to Your GM EcoTec3 V8 Powered Pickup Truck or SUV

K&N 57-3082 for 2015 Cadillac Escalade, '14–'15 Chevy Silverado, Suburban & Ta

The large seven-inch filter protects your engine while providing a large volume of air to draw from

The L83 and L86 GM small blocks, referred to in marketing materials as part of the EcoTec3 truck engine family, are some of the most advanced gasoline-powered engines to be made available in a full-sized pickup truck or SUV. The EcoTec3 engine family features three state-of-the-art technologies to make the most of power, torque, and efficiency across a broad range of operating conditions: direct fuel injection, cylinder deactivation, and continuously variable valve timing.

The EcoTec3 lineup consists of the three different power plants: a 5.3L V8 L83 and a 6.2L V8 L86, plus a V6 engine, all mated to six-speed transmissions when sold in the US and Canada. The 5.3L V-8 is rated at 355 horsepower and 383 lb-ft of torque, while the 6.2L V8 is rated at 420 horsepower and 450 lb-ft of torque. These motors are fitted to the 2015 Cadillac Escalade, 2014 – 2015 Chevrolet Silverado, Suburban, and Tahoe, and 2014 – 2015 GMC Sierra and Yukon 5.3L and 6.2L V8 models.

While you may be thinking that technologies like direct injection and continuous variable valve timing just improve fuel economy or may have some limited impact on performance, in fact they open the door for an improved power-making air intake system like the K&N 57-3082.

The K&N 57-3082 is designed to provide an increased flow of cooler air from outside the vehicle for your L83 and L86 motors to draw from. With more incoming air available, the ECU adds more fuel to match, and the engine produces more horsepower and torque.

And these aren’t empty claims. K&N has evaluated the performance of stock vehicles to those equipped with the 57-3082 air intake system, and these are the results: 2014 Silverado 1500 5.3L, an estimated increase of 10.68 horsepower, on a 2015 Tahoe 5.3L, an estimated increase of 15.39 horsepower, and on a 2014 Silverado 1500 6.2L, an estimated increase of 13.78 horsepower. And these are tested on a chassis dyno at the rear wheel, which reads lower than an engine tested out of the vehicle.

The K&N 57-3082 is a simple and straightforward installation that adds more power

Shielded from hot engine air, the air intake system can draw clean, fresh air for more power

No need to move or remove any other components other than the stock intake, as the K&N air intake system 57-3082 retains the original location of the air filter. The heat shield mounts in the factory air box location, but provides the filter far greater access to incoming cold air. The air filter utilizes K&N’s oiled cotton media in a seven-inch conical housing with a chrome cap and an ultra-strong molded pliable rubber flange which absorb vibration and allows for secure attachment at the bottom. The intake tube has mounting points for the factory mass air sensor and crank case vent hoses.

K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. Your engine can now draw a larger amount of air than the restrictive OEM filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range.

Installation of the K&N 57-3082 is simple, with easy-to-follow instructions available both on the website and packed with the kit. You need only basic hand tools and about 90 minutes of your time to increase the power and responsiveness of your L83 or L86 engine.

The only maintenance is a service you can do yourself in no time at all. At intervals of 100,000 miles (depending upon your driving conditions) by using the 99-5000 K&N air filter cleaner, you can easily clean and recharge your air filter, preparing it for 100,000 more miles of driving. Your one K&N air filter is designed to last for the lifetime of your vehicle, which K&N guarantees will perform for up to 10 years or 1,000,000 miles without requiring replacement.
