Description

The Forge Motorsports FMDVCS14A is a piston design bypass valve engineered as a direct replacement for your vehicle's original unit. It is recommended to service the valve every three years or 20,000 miles. Included in the box is the FMDVCS14A valve, an uprated yellow spring, and a Forge sticker. For optimal performance and to prevent potential P0101 trouble codes, reprogramming the ECM with a tune optimized for atmospheric discharge is advised when using this valve for atmospheric discharge. Compatibility notes indicate that if your vehicle has the valve shown in Figure 1, this Forge valve will fit. However, the valve shown in Figure 2 is not compatible. This change has been observed on vehicles produced post-2016, so please verify your existing valve before purchasing. An example of fitment includes the Vauxhall Astra GTC 1.4 turbo (B14NET(LUJ)), which is confirmed as compatible as a standalone modification.
