A supercharger helps force air into the engine for added horsepower. It mounts to your engine and is driven by a belt connected to your crankshaft. If you want to increase your vehicle's performance, a supercharger may be the perfect solution. To match the increased air intake, you may also want to upgrade your fuel delivery with a performance fuel pump and fuel injectors. This will help keep the fuel/air mixture at the proper ratio for peak horsepower. If you want to get more out of your vehicle, check out O'Reilly Auto Parts.
