I received a email from AAM regurding there new oil catch can for the GTR. This is perhaps the coolest catch can I've seen. Single can instead of two. Yes it's expensive but serves a great purpose and the filtration system is sweet.
I called AAM Friday about this and they do plan to make them for the 370 and 350. The only difference is the mounting bracket. I think I'm going to buy.
