Maybe I'm the one that is confused? You folks are talking about the manifold side gasket or the MAF side gasket? I'm talking about the silicone joiner for the maf to the air filter.
The black and blue part in the picture below is the silicone joiner/gasket between the MAF and the air filter. Are you talking about the other side? I can't remember but is the gasket for that already a part of the elbow?
