STILLEN 2012-2020 Nissan 370Z [Z34] (Base and Touring) Supercharger - Tuner Kit [Polished] - 407772TP

Unleash serious, driveable power from your Nissan 370Z with the STILLEN Polished Supercharger Tuner Kit. Built around the proven Vortech V-3 centrifugal supercharger, this system delivers massive horsepower gains while maintaining factory-like drivability, reliability, and fuel economy during normal cruising.

This Tuner Kit configuration is ideal for customers who already have access to an UPRev tuning cable or are working with an UPRev-certified tuner. All required hardware and the STILLEN-developed tune file are included — tuner cable is NOT included.

With an advanced air-to-water intercooler, a purpose-built cast aluminum intake manifold, and factory ECU recalibration, this system transforms the VQ37 engine into a smooth, linear, high-output performer suitable for daily driving, spirited canyon runs, and track use.

What Makes It STILLEN

STILLEN engineered a cast aluminum intake manifold with optimized runner length and plenum volume to maximize airflow and throttle response. The integrated air-to-water intercooler dramatically reduces intake temperatures, ensuring consistent power even under aggressive driving conditions.

The Vortech V-3 supercharger features a quiet V-belt drive and offers additional headroom for future upgrades. STILLEN rigorously tested this system on both street and track, including repeated high-speed runs and extensive thermal monitoring — because the VQ37 demands proper cooling to survive long-term boost.
