I got the 710N diverter valve in the maile yesterday and inatalled it along with new NGK plat's. This was the first time I had installed plugs in this car, the ones i took out were bosch supers with 3 prongs. They looked only a little crispy. I can tell a difference with the new DV cuz i drove the car inbetween installations. Plus, the resistance of the plate on the inside of the old DV was weak compared to the new one. I assume there is more air pressure maintained in the system before it diverts the air because of that. With new plugs and the DV the difference is definately noticeable. More throtle response and the turbo seems to boost more and longer throughout RPM's. Well worth the $50 paid, and even more rewarding knowing that i probably saved $150 in labor from the stealer.

 

The stock dv holds up to 8 lbs of boost where as the 710N is made for the 1 bar configuration. Was your old DV leaking. Glad to hear the car is running good
