The integrated merge spike reduces turbulence, decreasing air resistance to allow your engine to operate at maximum capacity. Further, the device has a race-system technology and performance dyno testing, responsible for better scavenging. Overall, the directional airflow and the reduced back-pressure improves the operation and the sound of your truck for a smooth driving experience.

Your fixture cannot be affected by corrosion, rust, scratches, and scuffs as it has a polished steel surface.
