Overview

The Turbosmart Kompact Dual Port Blow Off Valve is a direct-fit replacement designed for the Subaru 98-00 Forester GT and MY99 WRX.

Show original supplier description
The Turbosmart Kompact Dual Port Blow Off Valve is engineered as a direct-fit solution for the Subaru 98-00 Forester GT and MY99 WRX models. This valve uniquely combines atmospheric venting for the characteristic blow-off valve sound with recirculation back into the air intake for quieter operation during normal driving. Its dual outlet design with sequential timing allows for a performance-oriented sound when demanded, while maintaining subtlety under lighter loads. It effectively combats compressor surge, a common issue with aging or failing stock valves that can lead to performance loss and boost leaks. This robust construction ensures excellent boost-holding capability, vital for maintaining turbo performance. The Kompact Dual Port is an ideal upgrade for owners of stock to lightly modified vehicles seeking the desirable vent-to-atmosphere blow-off valve sound in a compact, OEM-replacement package. It addresses the shortcomings of standard valves that may not adequately prevent compressor surge and can degrade over time. Important Note: This product does not have a CARB EO # and is not legal for sale or use in California on pollution-controlled motor vehicles. It is intended as a 'Race Only' product for competition use only. Use is limited to closed-course and open-course racing sanctioned by a recognized racing organization. Any other use may be a violation of local, state, and federal laws. The buyer is responsible for verifying legal use for their intended application.
