    2 Top Rated Questions

    Any additional heat in the engine (PCM, wires etc.) compartment? Can the lower splash guard be vented to help exit the heat generated by the Roush stage 2 Supercharger. I like the Roush large grill and a tall hood to restore the strut tower brace and maybe additional ventilation. Need to here before I buy the catted headers idle/cruse sounds preferably with a toggle switch muffler damping system. My carbureted Corvette with Flow Master mufflers pass DEQ sound checks. I still set off car alarms in parking lots. ‘01 Ford supercab 5.4l 4X4 long header exhaust with a Magnaflow muffler and 9” lift for 37” Nitto Grapplers is fine.

    Will I need to purchase O2 sensor extensions? If so, will they be needed on both the front and back sensors or just the back?

    • No, you will not need to purchase O2 sensor extensions. This kit will include the required extensions for the install.
