Construction & Design

The intake system features precision-crafted 6061-T6 aluminum tubing, known for its lightweight strength and excellent corrosion resistance. The wrinkle black powder-coated finish not only adds a distinctive, aggressive look but also protects the tubing from heat and wear. Smooth mandrel bends in the tubing reduce airflow restrictions, allowing the engine to breathe more efficiently and respond quicker to throttle inputs.

The air filter is strategically positioned behind a diamond plate heat shield that minimizes heat soak from the engine bay. This design ensures the intake draws in cooler, denser air, which improves combustion efficiency and overall engine performance while maintaining reliability under various driving conditions.
