STILLEN 2012-2020 Nissan 370Z [Z34] (Base and Touring) Supercharger Tuned System [Polished] - 407772P

The STILLEN 407772P Polished Supercharger Tuned System is a complete, turnkey forced-induction solution for 2012–2020 Nissan 370Z Base and Touring models. Built around the proven Vortech V-3 centrifugal supercharger and STILLEN’s proprietary air-to-water intercooler system, this kit delivers massive horsepower gains while retaining daily drivability.

Expect 480–520 HP at the flywheel and a typical 380–450 WHP depending on supporting mods, fuel quality, elevation, and conditions — all while maintaining near-stock fuel economy during light-throttle cruising.

Driveable Power — The STILLEN Difference

At low RPM and light throttle, this supercharged 370Z behaves nearly stock — quiet, smooth, and predictable. But crack the throttle, and the Vortech V-3 spools hard, delivering a relentless, linear surge of power that transforms the VQ37 into an entirely different animal.

This is usable horsepower, not peaky dyno numbers — engineered for real-world performance.

Engineering & Reliability

Developed over more than a year of testing, STILLEN engineers focused heavily on:

• ECU fuel management
• Intake air temperature control
• Oil temperature stability
• Long-term street reliability

Testing included 140+ mph runs, aggressive track driving, and constant monitoring of air and fluid temperatures to ensure durability under real abuse.

Warranty

• Available 3-Year / 36,000-Mile Powertrain Warranty*
