I forgot to add that when I ordered the gasket from the dealer I told them it was for an evo ix not viii and they "claimed" there was no difference and that it was the same part? I hope I don't have to take it back off to change the gasket if its going to screw with my afr since it was a ***** to install I broke a bolt off in the housing and an easy out off in the drilled bolt lol. Took me three weeks to swap manifolds and this part lmao, and I had to hack my carbing skid plate up, well cut a hole for the pipe to come through.

 

awdordie, did you get the problem fixed?

 

Yes. The junk ebay manifold the previous owner had installed ended up cracking halfway around the first runner, and on runners 3 and 4 where the antilag ports were had cracks in the underside. It had a total of like 5 small cracks and a large crack all were not visible with the manifold on the head. Only after I pulled it did I find them. Put the stocker back on and fixed the problem.
