PRODUCT DESCRIPTION
This valve kit allows the installation of a fast-response black Forge blow-off valve on 1.2 TSi ZBZA, CBZA, CBZB, and CBZC engines, found in Seat Ibiza, Toledo, Altea, and Leon models, as well as VW Polo, Caddy, New Beetle, Jetta, Touran, and Golf, Skoda Yeti, Fabia, and Octavia, and Audi A1 and A3 up to 2015.
Since the engine does not include a bypass valve as standard, this valve not only provides an incredibly powerful sound when releasing the accelerator during gear changes, but also improves throttle response by reducing lag, as it helps the turbocharger maintain its rotational speed for when accelerating.
The sound is perfect and installation is simple, using only a few basic tools. Box contents:
1 FMDV12VAG valve
1 vacuum tap, gasket, and screws
2 M6 x 16 socket head screws
1 machined aluminum coupler
1 reinforced blue spring
2 cable ties
1 silicone hose
2 hose clamps
1 instruction manual
1 Forge sticker
Please note that this part is ONLY compatible with the 1.2 engine with CBZA and CBZB codes; NOT with later CJZA and CJZB models.
Color: Blue
