What year is your car? Have you got a 'g' revision OEM diverter valve? Many argue that the problems associated with the stock DV have been solved by the 'g' version. I dont recall seeing any hardcore proof that this is the case though.
In all honesty, the forge is a much better product - the quality is second to none, and there will be no worries that it will fail. You are obviously worried that your stock valve will fail - as you are contemplating the forge. Buying the forge will therefore eliminate those worries.
Few peeps on here have fitted it themselves, im sure they will be more than willing to help you!
