The Injen Evolution cold air intake for 2007.5–2009 Dodge/RAM 6.7L Cummins is a drop-in roto-molded system tuned to increase airflow and torque. It uses a two-piece housing with boost plenum, a large SuperNano‑Web dry filter, smooth intake tube, stainless hardware and reinforced silicone couplers. No cutting is required; dyno testing indicates gains of about 20 hp and 53 ft‑lbs of torque, with an OE-like fit under the hood.
