Customer Comments
'I would just like the thank your director for the advice on the the help he gave me when purchasing a dump valve for my Golf GTI. After phoning Turbo Technics in Durham and not getting the advice I was after I got it from you and with prompt delivery. The item worked superbly, and I also found a split in the rubber that your director said I should see to so I followed his advice and purchased that as well and now my car drives as expected - Thanks again!'

Diverter Valve Relocation Kit for VAG 1.8T 150/180 hp
This kit allows you to relocate the diverter valve from the hot side of the turbo to the cold side of the intercooler on the VW Golf, SEAT Leon (not Ibiza), Skoda Octavia and Audi A3, TT 1.8T engines of 150 - 180 HP. For the 210/225 versions of this engine please see FMDV225RLK
By relocating the valve in this way there are two benefits. Firstly, due to operating in lower temperatures the longevity of the valve is increased. Secondly, after relocation, the air that is recirculated back into the intake tract to the turbo will be cooler. Cooler air has a greater density. The greater the density of the charge mix in the cylinder the more power generated on combustion.

Please be aware that these hoses were patterned from right hand drive vehicles. Whilst we believe these to be correct for left hand drive vehicles we suggest that you visually check their suitability, as replacement items, with those fitted to your own vehicle, before attempting installation.
