The first step in upgrading your car’s performance is to replace the restrictive stock air box with a STILLEN Hi-Flow Intake. 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 either a precision machined ring and a gauze element (cleanable) filter or the newer K&N cone filters which incorporate a velocity stack which uses the venturi effect to accelerate air intake speed. Power and throttle response will improve throughout the entire RPM range. Your best dollar-per-horsepower investment by far! Most people find the authoritative note of the intake pleasing, but note that increased noise levels will result. Clean your filter regularly for best results.
