Subaru Trezia (NCP120X/125X) Supercharger Kits

The supercharger system provides instant progressive power.
Rotrex superchargers operate much cooler when compared to turbochargers and other supercharger systems, which reduces the engine’s intake air temperature as well as its risk of detonation.

The light body and ROTREX match, and comfortable acceleration continues beautifully up to high revs. We have realized easy-to-use power without lag from city riding to the circuit.

A completely bolt-on vehicle inspection compatible
