This system works with both manual and automatic Mustang GTs and includes all required hardware, fasteners, brackets, and instructions (no supplemental kit required).
Please note that this 2009 Mustang Supercharger only works for Mustang GTs with the 4.6L, 3-valve V8 engine.
The components of this 2009 Mustang Supercharger kit include a roots-style ROUSH M90 supercharger, air-to-water intercooler system, 73mm supercharger pulley (generating 5 PSI of boost), intake manifold, and high-flow fuel injectors and induction system.
A hidden but key feature of this system is the ROUSH® PCM calibration. To maximize the performance of any supercharger system, you must have a highly refined calibration. Consequently, ROUSH provides the most highly refined calibrations in the Mustang supercharger market, resulting in industry-leading reliability, performance, and engine durability across the gamut of environmental and load conditions. No competitive system comes close. That's why ROUSH® stands behind its superchargers with an industry-leading 3 year / 36,000 mile drivetrain warranty, or one year on ROUSH® components for vehicles that are past their warranty expiration date.
This 2009 Mustang Supercharger kit is 50 state legal.
