The TurboXS RFL blow off valve kit will give you that classic blow off valve sound that always turns heads and scares small children.

The TurboXS RFL valve will allow your car to hold more boost and will not leak under stock or even increased boost levels. The TurboXS RFL valve features an attractive polished finish and is flanged to directly mount on the WRX top mount intercooler for a headache free installation.
