You will also receive a premium, silicone coupler that features reinforced, weaved fibers for a superior seal between the induction tube and the turbo inlet.

The engineers at ROUSH Performance kept the customer in mind when fabricating this kit by utilizing and upgrading the factory PCM calibration. In addition to long-lasting, durable components, this kit keeps the factory PCV connection so no drilling or cutting to any of the components are required.
