Boasting a World Rally Championship lineage, the Subaru Impreza WRX makes no excuses for itself as a road-going rally car. Its combination of a turbocharged boxer engine along with a high-performance AWD system makes for a car that is responsive and maneuverable yet very stable under any road condition. In fact, few things can compare to the exhilarating feeling of driving a WRX…except the feeling of driving a WRX prepared by XS Engineering, of course.

We knew of its many virtues from its exploits overseas and it goes without saying that we were excited to find that the WRX was slated to come to the United States for 2002. Finally, an affordable, turbocharged, AWD car will be available to take over the segment that the Mitsubishi Eclipse once held. While eagerly anticipating its debut, we began working at a feverish pace to develop parts to push its performance envelope. By October of 2001, the first prototype intake, exhaust, intercooler and turbocharger systems rolled out on several WRX's in time to be showcased during the 2001 SEMA show. The consumer response to that was more than overwhelming and we, as a result, have moved those parts into full production. It is our intent to provide our customers with a complete 'tuning menu' for the WRX that will cover engine, suspension, engine management, and aerodynamic enhancements. The WRX has quickly become one of our favorite cars and as such, its limits will continue to be pushed in order for us to supply you with the best parts available.

All of our parts are developed on one of our in-house chassis dynamometers or engine dynamometer. This way we know exactly how our parts react on a car. You can view dyno sheets on most of our products to see the documented gains in power and torque. To view a stock WRX dynosheet, click here (dynosheet1). We are dedicated to making useable horsepower and this is why ALL of our parts make power. We do not do our research and development or manufacturing in a garage and then sell parts on the internet. XS Engineering is here to service you today and will be here tomorrow as well.
