Was wondering how much work to cut open the IC and convert it from triple pass to single pass....would be a massive performance boost in lowering IAT's. Likely way too much work and obviously way beyond my abilities!

Since you worked on my car I have separated cooling with a small res - to confirm what I suspect is my IC is leaking and have a replacement IC from Grip Grip ready to go. Also swapping out HE with a E55AMG HE next week. Still not enough to avoid meth/ice I assume?
