STILLEN 2009-2011 Nissan 370Z [Z34] Nismo Supercharger Tuner Kit [Polished] - 407770NTP

The STILLEN Polished Supercharger Tuner Kit for the 2009–2011 Nissan 370Z Nismo is designed for enthusiasts who want maximum forced-induction performance while controlling the tuning process themselves. This tuner kit provides all hardware for STILLEN’s proven VQ37 supercharger system—without bundled tuning.

At the core is a polished Vortech V-3 centrifugal supercharger, paired with an integrated air-to-water intercooler built into STILLEN’s custom cast aluminum intake manifold. The intercooler ensures intake air remains cool at the engine entry point, maximizing performance while preventing heat soak.

Typical output ranges from 380–450 wheel horsepower, depending on modifications, fuel quality, elevation, and tuning. Even with these gains, the system retains stock-like fuel economy during low-RPM cruising, giving you aggressive performance with daily drivability.

The intake manifold features longer runners and a large plenum for increased airflow and torque, while the front-mounted compact heat exchanger optimizes cooling efficiency for critical engine components. The Vortech V-3 unit features a self-contained oiling system, quiet operation, and upgradeable potential for future performance enhancements.

Extensive testing, including track abuse and real-world driving, ensures both reliability and street drivability. The system delivers smooth, linear power at all RPMs while giving you explosive acceleration when demanded.
