i bought the manifold from eurostyle and i used eric's kit from m50manifold.com. the install is very straight forward. the biggest problem i had was the manifold bolt in the back. labelling all the harnesses helps a ton. it took me about 7 hours by myself.
do you think a cracked/ripped intake boot would cause the CEL? I used the original one which did have some tearing. I'm going to BMW tomorrow to buy a new one.
