Injen Evolution Cold Air Intake System RAM Cummins Diesel

The Injen Evolution Cold Air Intake System is a performance air intake (cold air intake, CAI) built for RAM trucks with Cummins turbo diesel engines. It replaces the restrictive factory airbox and intake tract. The goal is better airflow and cooler, denser intake air, with horsepower and torque gains and a more aggressive intake sound under acceleration.

Key Features:

• Dyno-tuned design: Injen tests and tunes each system on its in-house dyno. The tuning is meant to work with stock fueling, and it is intended to give gains across the powerband without needing an expensive tune.
• Roto-molded intake tube: A custom, smooth-walled tube reduces restriction while keeping an OE-quality fit.
• Durable construction: The housing and tube are made in the USA from cross-linked high-density polyethylene (XLPE).
• Quality hardware: Stainless steel hardware and reinforced automotive-grade couplers give a secure, leak-free seal.
• Ram air box design: Select applications use a molded ram air scoop and boost plenum to draw in cooler outside air.
• High-flow filter: A serviceable Injen SuperNano-Web dry air filter is used on dry-filter versions. It is reusable, and it needs no oiling.
• 3D-engineered fit: Each kit is designed in 3D for a straightforward bolt-on installation.

Injen has made performance intake systems for many years. The Evolution series carries that experience over to diesel trucks, with a clean under-hood look and gains verified on the dyno.
