Has anyone used the ECS Tuning n75 race valve? Seems as if my n75 has gone bad and I'm going to replace it, so I might as well upgrade if it's worth it. Looking for a review or some opinions/thoughts on it vs. the stock n75 vs. EBC. I've searched around and found some good articles, but I'm still looking for more input. It seems to me like the EBC would be the way to go, but it also has it's disadvantages. Let me know what you guys think.

 

I think this article may help you with regards to you questions on the N75 :

034 906 283 J = stock 3B (in 200 20v and S2)
034 906 283 H = stock AAN (UrS4 and UrS6)
034 906 283 K = S2 ABY and RS2 ADU

 

Very informative article and thanks for the help. Still looking for some input on an ebc or the n75 "race" valve.
