At Magnuson we believe you should be able to have big horsepower, drivability, and a long-lasting, reliable product. In fact we’ve been making power you can live with for more than thirty years. We’ve used what we learned to develop Magnuson Supercharger Kits - the best-selling, most complete line of bolt on superchargers anywhere. We test each Magnuson Supercharger before it leaves the factory, and we stand behind our product with a 3 year/36,000 mile warranty. It’s going to run like it was factory installed because we manufacture and calibrate to OEM standards. Just ask our OEM customers. We also use Eaton rotors exclusively - the same supercharger rotors found in virtually all of the OEM supercharged applications from Audi, GM, Jaguar, and Ford. 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.
