hello all.
I recently purchased an opel astra g z22se and I would like to put the 2.4L intake manifold.
The problem is that I bought one in the U.S. but it is not like I've seen here. In the store of purchase admission, they said it was for the 2.4L engine but it is like that of the 2.2L engine.

I've looked at some American pages and looks like using the chevrolet malibu 2.4L of 2010 but not ion or cobalt.
The reference number that I've bought is # 12602735
but I think yours is # 12587878
You think that would serve me that I have?
Thanks and sorry for my bad English
A greeting
