Injen 01-04 GMC Duramax LB7 6.6L Evolution Intake - #EVO7008
The Evolution of cold air intakes is here. The Evolution cold air intake system by Injen Technology is the next generation of performance intake systems. The EVO7008 is specifically engineered for the 2001-2004 GM Diesel trucks with the 6.6L LB7 Duramax engine. Every EVO7008 cold air intake is made in the USA from cross linked high density polyethylene for extreme durability. They include stainless steel hardware and automotive grade urethane couplers. No cutting or drilling required for an easy installation process that does not require aftermarket tuning for exceptional HORSEPOWER and TORQUE GAINS.
The EVO7008 was precisely tuned and tested on our in-house dyno to replicate stock fueling while increasing horsepower and torque. The EVO7008 system features our 2-piece box design that incorporates our boost plenum, a massive 360 degree SuperNano-Web dry air filter, a smooth Rotomolded induction tube for reduced restriction levels, and premium hardware. Every Injen Evolution air induction system utilizes Injen’s proprietary SuperNano-Web dry air filters. The Evolution induction systems utilize some of the largest filters on the market employing super deep filter pleats, with some measuring over 1.25”deep! This particular intake kit also features our SHUR-LOCK mounting system on the air filter to ensure a non-slip seal. The EVO7008 cold air intake system was designed to use the maximum space available under the hood to ensure optimum breathing room and extreme performance. The Evolution can’t be stopped…..
Roto-molded Housing and Boost Plenum:
The EVO7008 system features our 2-piece box design that incorporates our boost plenum. Designed in 3D ensures a hassle free, drop-in installation.
The EVO7008 Evolution Cold Air Intake System uses a custom designed and dyno-tuned intake tube to produce huge power gains while retaining an OE quality fit.
SuperNano-Web Dry Air Filter:
"That’s massive!” is all you will hear about this SuperNano-Web Dry air filter that is included with the EVO7008 cold air intake system. Using the largest filter possible for this application has increased the available air volume - resulting in added power while keeping the installation process quick and simple.
From the Stainless Steel Band Clamps with an inner protective liner to the reinforced automotive grade silicone coupler, every aspect is covered for a perfect and secure fit.
Hassle-Free Installation:
Make it easy! By designing this kit in a 3D workspace, you’re ensured a quick and easy installation that not only increases the power output of your engine, but also provides a clean and powerful look that others see every time you pop your hood.
Clean and simple, NUMBERS talk! Injen has put in the time and diligence to stand behind our performance data. We put in the time to test and prove that we have developed a superior kit for your GM Duramax LB7. After hours of designing and dyno testing, Injen is proud to say that the EVO7008 Evolution Air Intake system puts down numbers of up to 21 additional horsepower and 43 Ft.-lbs. of torque.
