Upgraded valve for the Suzuki Swift Sport 1.4 ZC33S and 1.0 BoosterJet. Also fits the Vitara with the 1.0 or 1.4 BoosterJet engine when the engine cover has been removed. The FMDV47 model is required for the hybrid version.
The Forge Motorsport atmospheric valve is more than just a replacement for the original diaphragm bypass valve – part no. 18119-65H70. It is serviceable, offers a fast response and a distinctive sound, and its operation can be tailored to the needs of a modified vehicle.
