High Flow Bundle Kit Stage 2 for 2020-2023 Duramax L5P Illusion Purple

High-flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly. Replaces restrictive plastic factory parts for improved engine performance. Increases air flow to the turbo, producing improved horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the hood Ram Air duct and inner fender. All aluminum construction features large diameter 4" piping with smooth aerodynamic bends to improve intake air velocity, volume, and provide more aggressive engine and turbo sound during acceleration. The intake horn is over an inch larger than the OEM diameter and improves air flow to the turbo by removing restriction found in the factory horn right before the turbo inlet. Full assembly finished in your choice of WCFab's signature custom powder coat colors.
