Injen 05.5-07 GMC Duramax LBZ/LLY 6.6L Evolution Intake

Injen is known for performance intake systems that help your engine breathe easier. This Evolution cold air intake is built specifically for your 2006-2007 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the 6.6L Duramax LBZ or LLY diesel engine. It's designed to replace the restrictive factory airbox and tubing, allowing for a smoother, less restricted path for air to enter your engine. This can lead to improved throttle response and more power.

This intake system is constructed in the USA from durable, cross-linked high-density polyethylene for the housing and intake tube, which helps keep intake air temperatures down. It features a large, 360-degree SuperNano-Web dry air filter with deep pleats to capture more dirt and debris. The housing includes a boost plenum, and the entire setup is designed to fit like a factory part, meaning no cutting or drilling is needed for installation. Injen has dyno-tested this system and found it can add up to 30 horsepower and 62 ft-lbs of torque without requiring an aftermarket tune.

The kit comes with stainless steel hardware and automotive-grade urethane couplers for a secure and lasting installation. You'll also notice a more aggressive intake growl under acceleration, letting you know the engine is getting all the air it needs.
