Stillen 402900 Hi-Flow Intake Kit 90-96 Nissan 300ZX
The first step in upgrading Z performance. Additional air flow increases the engine's efficiency and power output by increasing the quantity of the air/fuel ratio. The STILLEN Hi-Flow consists of a precision machined ring and a gauze element (cleanable) filter. The ring surface achieves a venturi laminar air flow for optimum efficiency. The addition of the STILLEN Hi-Flow alone has been dyno tested at an extra 20 horsepower on the twin turbo model. (Gains on the non-turbo model are significant as well.) Power and throttle response will improve throughout the entire RPM range. With CARB approval, the STILLEN Hi-Flow intake is 50 state legal. Clean your filter regularly for best results.
