Built for performance and show, the HPS Red cold air intake kit for 2015-2016 Subaru Impreza WRX STI 2.5L Turbo relocates HPS Performance Air Filter outside of the engine compartment to deliver the coolest air inlet temperatures.

The heavy duty powder coated steel heat shield blocks off hot air from the engine compartment for the best cooling effect.
