Injen Evolution Cold Air Intake System GM Duramax

The Injen Evolution Cold Air Intake System is a performance air intake for GM Duramax 6.6L turbo diesel trucks. It replaces the restrictive factory airbox and intake tube. It uses a sealed design that draws in cooler, denser air for stronger throttle response, better airflow and a more aggressive intake sound. Each kit is engineered for a specific Duramax engine generation.

Key Features:

• Dyno-tested performance: Injen developed and tested the system on its in-house dyno to add horsepower and torque while working with the stock calibration. An aftermarket tune is not required.
• Boost plenum housing: The two-piece roto-molded box includes a boost plenum that feeds the filter with cool air.
• SuperNano-Web air filter: The 360-degree, fully serviceable Injen SuperNano-Web filter uses a dry or oiled media, depending on the kit.
• Smooth induction tube: The roto-molded intake tube is designed for a smooth, low-restriction air path.
• Durable materials: The housing and tube are made from cross-linked high-density polyethylene. The kit includes reinforced automotive-grade couplers and stainless steel hardware and band clamps.
• Easy installation: The system bolts into factory mounting points with no cutting or drilling.
• Made in the USA: Injen builds these systems in Pomona, California.

Injen Technology has built performance intake systems for many years. The Evolution series gives Duramax owners a direct-fit upgrade that keeps an OE-style fit under the hood.
