Most Magnuson Supercharger Kits carry a CARB EO# and are 50-state emissions legal for on-road use. Magnuson kits are known for their driveability and reliability, achieved through our Powertrain Integration approach. Simply put, this is the process of recalibrating the engine and transmission control programs to work with the altered induction path and boost pressure of the supercharger. This results in a seamless and consistent delivery of power over the entire RPM range, not just high end. It also means that your vehicle will continue to meet emissions and fuel economy standards.
