Part #: GS355BPV GS355BPV - Gothspeed Bypass Valve


This bypass valve was designed as a direct OE retrofit for the Ferrari F355 and F50, no other parts needed. This new valve design will quietly and reliably perform OE exhaust gas switching responsibilities. It also utilizes an upgraded vacuum actuator for seamless operation with the OE system.

The new bypass valve 'action' has been pre-tuned and needs NO adjustments.  The new valve should be handled with great care, especially during the installation process.  Installation should be performed by a skilled Ferrari technician... or, as a second-resort an owner whom is experienced in the installation and removal of the:  intake air boxes, MAF, heat shield, and exhaust components.

This is a direct fit replacement for Ferrari part 155006
