AmD engraved, Turbo Dynamics Viper recirculating Diverter valve. Replaces the standard Bosch 1.8T Plastic diverter valve, with a servicable more robust piston style valve. This item has served me well. On removal from my car, I cleaned and serviced it with new grease and O-rings. Recipient will also receive a plentiful supply of spare O-Rings, any grease I have left over, a spare but used (weaker)spring and some spacers I had made for "DV Shimming" if you wish to play. ( at your own risk) I may also include some spare cap head screws for the lid if I still have any. Please ensure it is the correct fitment for your car. Â£30 posted UK ONLY. Thank you. Item is packaged and ready to go. Just need payment and and address.
