I will be honest and say it was a struggle to install the oil cooler and cover ! All the holes did not line up because the 90 braided oil fitting were pushing against the cover. After much trying I finally opened the holes on the cover to 1/2.I spent 3/4 of my install on the cooler and cover install itself. I also did not receive rubber tubing for the oil lines in case of rubbing. I improvised. And the crows foot is useless. I only made three attempts to tighten before it began slipping on the fittings. Everything else was easy. I remain positive that the unit will operate as described and keep my oil much cooler.
