Magnuson intercooled supercharger for the 2008-Early 2009 G8 GT with a manual transmission retains factory-like drivability, fuel economy, and reliability while providing significant peak horsepower and torque gains.

This kit includes a large liquid-to-air intercooler inside the supercharger manifold to keep air temperatures down, a front-mounted heat exchanger, electric water pump, and intercooler coolant reservoir. The integrated bypass valve used maximizes efficiency during cruising and allows your supercharged G8 GT to maintain stock-like drivability and fuel economy.

The supercharger intake manifold, inlet, pulley, fuel rails, front & rear fuel crossovers, and intercooler come pre-assembled to make installation simple and easy while the accessory box is organized into individual sub-assemblies to help ensure that you don’t lose track of parts during your install. All necessary hardware is included for a complete installation.

The Magnuson MP2300 TVS supercharger utilizes EATON’s latest 6th Generation supercharger rotor technology for a highly efficient package that requires less power to drive, and delivers cooler discharge temperatures.

Power gains of approximately 120 horsepower and 120 foot-pounds of torque at the rear wheels!
