USP Motorsports Releases Air Intake System for Seventh Generation Golf, GTI, Golf R and MQB Audi A3 Share Comments USP Motorsports is proud to offer a complete closed element air intake system for the MK7 GTI, Golf, Golf R and Audi A3. After testing several designs, USP chose to go with a closed element intake system which is fed directly through the front grill of the vehicle. Starting at the turbo, USP incorporates the SPULEN silicone turbo inlet hose which provides a smoother path for air flow. In addition to increased air flow, the silicone turbo inlet hose is stronger and more durable than the factory plastic hose. The turbo inlet hose is joined to a closed element carbon fiber canister filter. The canister filter does not just look good but also performs. Constructed of carbon fiber and incorporating a high flow air filter, this filter was the perfect choice. Finishing the intake off is USP’s patent-pending Tear-Duct. Not just a normal intake snorkel, the Tear-Duct has specifically been designed to allow maximum air into your engine. As air enters the front of your vehicle it is captured and compressed at the Duct. As air moves through the Duct, it is further compressed by the “Tear Drop” design located at the rear of the duct. The “Tear Drop” not only compresses the air but also increases flow allowing more air to be pulled into the engine. Dyno testing yielded exception power results through-out the RPM range. Users can expect to see gains of 8-16 wheel horsepower and 10-16 ft/lbs of torque at the wheels. Modified vehicles will experience larger power gains.
