For a long time, California has been the thorn in the side of many aftermarket companies. With CAFE and EPA regulations breathing down the necks and rejecting many go-fast goodies from our favorite parts suppliers, those of us living on the West Coast had to make due with “50-state legal” requirements.  If you’re a 2011+ 5.0L Mustang owner, you can rejoice. ROUSH Performance has found a way to offer enthusiasts a supercharger system that provides the horsepower you’re looking for while keeping the California “sniffer” happy.

Official Release:

2011-2013 5.0L Mustang Phase 1 Superchargers Are Now Legal In All 50 States

ROUSH Performance will immediately start shipping 5.0L Phase 1 Mustang Superchargers to California. “We have been eagerly waiting for the green light and are now excited to have received our CARB E.O. number for our 2011-2013 Mustang Phase 1-575hp supercharger kit”, states Tony Marszalek, Director, Performance Products. “This now allows for us to sell the 575hp supercharger kits into all 50 states and Canada.” The Phase 1 ROUSHcharger kits work on both automatic and manual transmission 5.0L 4v V8 Mustangs and are also available with an optional 3 year/36,000 mile powertrain warranty.
