Additional Information

Cold Side Crossover Pipe: Features a smooth interior finish and circular cross-section for superior airflow dynamics compared to stock. A four-axis CNC-machined flange ensures seamless transitions into the intake plenum, reducing turbulence and improving performance. For those ditching the throttle valve, the kit further minimizes restrictions by eliminating the grid heater and throttle valve assembly.

Passenger-Side Intercooler Pipe: This oversized 3.5" pipe (vs. the failure-prone 3" OEM version) delivers smoother airflow, greater durability, and a precise fit. Say goodbye to weak spots and airflow bottlenecks.

Driver's-Side Intercooler Pipe: A durable two-piece design made to make installation significantly easier in a tight engine bay.
