      Description 

      Yet another first for Forge Motorsport! This valve kit allows the fitment of a fast response blow off valve on the 1.2 TSi engine ZBZA, CBZA, CBZB and CBZC as found in the Seat Ibiza, Toledo, Altea, Leon, the VW Polo, Caddy, New Beetle, Jetta, Touran, Golf, the Skoda Yeti, Fabia, Octavia, and the Audi A1 and A3 up to 2015.

      As the engine does not have a diverter valve fitted as standard, this valve not only gives you an incredible loud sound when lifting off the throttle during gear changes, but will also improve the throttle response by reducing any lag, as it will help the turbocharger maintain its rotational speed ready for when you accelerate.

      Mk5 R32 Turbo. I have had the best experience top quality service I would not think about going anywhere else! From helping me install my ecu over the phone with help on wiring sensors troubleshooting I would have been totally lost not to mention the remote mapping service so I was able to fit it in around work and other things the car runs like a dream pulls hard in all gears and is music to my ears. I will not take my cars anywhere else 5* Thank you for bringing my project to life

      Something came up that required me to get a car part urgently and under a time limit and I was having trouble tracking down local businesses that could source it for me. Luckily, I came across Sameer’s contact information and reached out. He was brilliant - answered my query over the phone, got the part ordered as soon as was physically possible and kept me updated every step of the order and delivery process. He solved my issue with professionalism and expertise. Very happy with the service received.

      Sam always does a quality job when it's comes to mapping my car. It has been with Sam multiple times for mapping, tweeking and problem solving and is very knowledgeable when it comes to ECU masters. The passion toward cars and mapping reflects in his work!
