Thread resurrection time..

Did you ever get any before and after figures m8? A thread on a facebook page has just reminded me I bought one of these manifolds in the Courtney sport group buy and never fitted it lol.

Hey Guys, I'm new here and have some questions about the LE5 intake:
You always used the one with the number GM 12587878 - so this one got really expensive now.
Does anybody has some experience with 12597953 or other ones which are much cheaper?
Did they just changed numbers?

the 12587878 is a much better inlet manifold (y)

the 12597953 was also fitted to some 2.2 engines and thus probably not much better than a standard z22se inlet manifold
