0ne tip for those installing. I ran across a small issue of my own doing. Drivers side. I didn't get the angle quite right on the pipe and the cover was pushing the filter off the end of itself... even when tightened down properly.
Solution for me was to rotate the coolant hose counter clockwise (looking at the car) about 45 degrees to allow the pipe to be more upright. It gave me more than an inch of gap between the hose and the intake also, which is good.
Again, not a product issue but one that I caused by not tightening down things in the right order. Though, i think rotating that hose ends up being a great way to give you more room on that side either way.
