*by B***K on May 28, 2014*

I bought an intercooler for cheap from a friend and it needed a new fill neck. The old one was crushed when his front-clip was shipped. It wasn't in stock so Amazon had to special order it. High quality peice and was welded professionally buy a local aluminum fabricator. Works awesome.
