IE set out to produce the highest performing air intake for the RS3 8V and TTRS 8S 5 cylinder turbocharged engine available. Extreme design measures were employed with a "no-corners-cut" attitude and no expenses spared. A massive air filter, built-in velocity stack, carbon fiber construction, large internal volume, and 4-inch piping diameter ensure the engine breathes sufficiently for any power setup and produces large power gains across the entire powerband.
