Injen 04.5-05 GMC Duramax LLY 6.6L Evolution Intake

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 EVO7001 is specifically engineered for the 2004.5-2005 GM Diesel trucks with the 6.6L LLY Duramax engine. Every EVO7001 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 EVO7001 was precisely tuned and tested on our in-house dyno to replicate stock fueling while increasing horsepower and torque. The system was carefully designed utilizing the latest in CMM Laser Scanning hardware - SolidWorks 3D CAD Software – and finally prototype tested after being printed on one of our state of the art 3D printers – and this is all before ever being released for production! The EVO7001 system features our 2-piece box design that incorporates our boost plenum, a massive 360° SuperNano-Web dry air filter, built-in Filter Monitor for quick and easy filter inspections, 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 EVO7001 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…..
