This 2005-2006 Mustang Supercharger kit works with both manual and automatic transmissions and comes with all needed instructions, fasteners, hardware, and brackets. No supplemental kits are required with this system. The heart of this 2005-2006 Mustang Supercharger is the M90 ROUSHcharger. This line of ROUSH Mustang supercharger kits has been thoroughly developed, used, and proven by ROUSH over thousands of production vehicles and has had several years of life out in the field. Not only is this Mustang supercharger a great value for getting a bump in performance, but it is virtually bullet-proof as well. That's why we stand behind this kit with an industry-leading 3 year / 36,000 mile drivetrain warranty or one year on ROUSH® components for vehicles already past their warranty expriation date. Please see the ROUSH warranty for more details. This supercharger is legal for use in all 50 U.S. states. This 2005-2006 Mustang Supercharger kit includes a roots-style ROUSH M90 supercharger, 73mm supercharger pulley (generating 5 PSI of boost), air-to-water intercooler system, intake manifold, and high-flow fuel injectors and induction system. Another key element of this system is the special ROUSH calibration. Not only is this element instrumental in maximizing performance, it is also key to protecting the engine from fuel mixture problems, such as burnt pistons, over the spectrum of environmental extremes. Once you purchase your 2005-2006 Mustang Supercharger, you simply need to ship your PCM unit to ROUSH. We will then update the calibration and send it back to you. Overnight shipping for the PCM is included for free. 2005-2006 Mustang Supercharger Dyno Chart
