V-3 Supercharger Tuner Kit with Air/Water Intercooler

The STILLEN 407737TB Supercharger Tuner Kit is engineered to dramatically enhance the performance of your 2008-2013 Infiniti G37 Coupe or 2014-2015 Infiniti Q60. This kit features a black Vortech V-3 supercharger unit and an advanced air-water intercooler system designed to chill the air charge immediately before it enters the engine. The front-mounted heat exchanger is strategically placed to maximize cool air flow to the engine while ensuring vital coolers like the radiator, engine oil cooler, transmission cooler, and power steering cooler remain unobstructed. This tuner kit is designed as a direct bolt-on for the VQ37HR engine, offering a substantial power increase. Expect to achieve approximately 480-520 horsepower at the flywheel, with typical rear-wheel horsepower output in the 380-450WHP range. It includes larger injectors and a new fuel pump to complement the remapped factory ECU, which manages improved airflow, operating temperatures, and power gains while maintaining 50-state emissions compliance (EO# D-436-20 for 2008-15 models). The main supercharger unit comes pre-assembled to laser-cut billet aluminum mounting brackets. A competent shop can typically complete the installation in approximately 12 hours. This tuner kit includes the tune file, but the tuner cable is not included; it is ideal for users who already possess a compatible UPRev tuner cable or are working with a certified UPRev tuner. The system also includes a 3-year/36,000-mile powertrain warranty, though certain conditions apply for eligibility. The Vortech V-3 unit features a self-contained oiling system and a quiet V-belt design, offering significant additional boost capability for future power upgrades. STILLEN has taken great care to ensure that all additional cooling systems function harmoniously with the intercooler system, addressing the VQ37 engine's tendency for high oil temperatures.
