Billet LT4 Supercharger Lid for Chevrolet Corvette Z06, Chevrolet Camaro ZL1 and Cadillac CTS-V

Modern muscle car enthusiasts, MPI wanted to create a unique supercharger lid that generates louder supercharger whine and a custom look that will set your vehicle apart from the others at Cars and Coffee! We also proved slight gains in power in a controlled testing environment.

Our LT4 lid reuses OEM gaskets and can be easily swapped out in less than 30 minutes on your car.
