Cayenne turbo 07 DV spring colour
I have a question regards to diverter valve. I wanna know what spring colour I should use for my cayenne turbo?*
I have the Forge DV
It has an ecu chip which is the only mod on the car but I am planning on changing air filters and secondary cat bypass down the line.
Putting in the blue spring now will if it affect anything?
Thanks*
