Stillen 402970 Hi-Flow Intake Kit 93-94 Nissan Altima
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 precision machined ring and a gauze element (cleanable) filter. Like a velocity stack, the ring 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 result. With CARB approval, most STILLEN Hi-Flow Intakes are 50 state legal. Clean your filter regularly for best results.
