Designed to replace the restrictive stock airbox, this advanced air intake system delivers impressively higher horsepower and torque levels, giving your vehicle the extra performance boost it deserves.

This high-quality air intake system provides significant enhancements with a 20 whp and 18 wtq gain over your stock intake, all while keeping your engine's air/fuel ratios safe and optimal.

To further enhance efficiency, the free-flowing air filter is placed outside the hot engine bay, complemented by a protective powder-coated heat shield, preventing heat-soak and ensuring cooler air intake temperatures.
