Subaru had a hit with their Impreza model. The well-mannered, safety sedan featured a boxer engine and all wheel drive drivetrain. This hit turned into a homerun with the WRX.
Subaru called their creation the WRX which stands for World Rally eXperimental. It took the basic Impreza, slapped on a turbo, and mixed in rally inspired tech throughout.
The Subaru Impreza WRX debuted in 1992 but wouldn’t be available to the US market until 10 years later for the 2004 model year. This model, designated chassis code GD, was equipped with a 2.0L turbocharged engine. This first generation US market WRX, affectionately referred to as “bug eye” for the shape of its headlights, remains one of the best “bang for buck” Subarus out there.
The release of the USDM Impreza WRX coincided with COBB Tuning becoming the go-to aftermarket tuning and Subaru parts solution. The rest is history.

Looking for an effective solution to eliminate inconsistent power delivery from your Subaru WRX or WRX STI? Look no further than the COBB Tuning Front Mount Intercooler. The factory top mount intercooler can easily be over worked and overheated due to its size and location. Thus, the intake air temperatures rise causing a loss in power. Replace your factory intercooler with the COBB Tuning Front Mount Intercooler to ensure that your engine is receiving the coolest possible air, giving you more power!
