I purchased the Roush cold air kit two months ago and it has been as advertised. Typical Roush quality and the installation was a breeze. Engine definitely breathes better. Minimal performance advantage but the engine runs smoother. Nice under hood appearance.

Yes, I would recommend this item to a friend!
