- This kit will fit the 2005-08 Roush supercharger kits. This kit does use the 90mm mass air housing for 2005-08 application.
- This kit adds a Billet 2.57 pulley and 90mm Billet Idler. The pulley will result in 7-8 lbs of boost total. Stock roushchargers are seeing 4-5 lbs of boost. The Billet idler is needed so that you can reuse your stock roush belt. You also recieve a pre-loaded SCT Tuner with the correct tune for your new cold air intake, 2.57 pulley and 90mm mass air.
- Adding this kit will void the Roush 3 year 36,000 mile warranty. We recommend using the Autolite HT0 plugs with this kit. This is the most you can do to a roushcharged car without upgrading the stock fuel system.
