Construction & Design

Manufactured in the USA, the Evolution Intake system features roto-molded cross-linked high-density polyethylene (XLPE), a material renowned for its exceptional durability, heat resistance, and chemical stability. This ensures the intake maintains structural integrity under demanding off-road and street driving conditions.

The modular two-piece air box integrates a boost plenum that optimizes airflow dynamics and allows seamless adaptation to additional intake components such as the Ram Air Scoop or snorkel. The induction tube is precision-engineered using CAD software and roto-molded to create smooth internal surfaces that minimize turbulence and maximize airflow efficiency. Stainless steel clamps with inner protective liners secure the silicone couplers, providing a tight, vibration-resistant seal that withstands engine bay stresses.
