I was really excited to have the piece to install my oil cooler and I thought it was this. It turns out that I was wrong. I went to install this but with how large this piece is, there isn't a real good angle for it to fit. Now, the sandwich plate itself is large, but once you add sensors that stick straight out, you just can't fit it nicely. Angle it down? No, the engine mounts are in the way. Forward? No, alternator is there. Angle it up? Wrong. Intake manifold is in the way. I had to end up having it face towards the back of the engine (face being the side with the AN lines and sensors). With AN line length possibly being a problem, I wasn't overly thrilled having to add another 4 inches of travel. That said, the piece itself is solidly built. Everything fits nice and appears to be quality. I'll say this: the adapter is much more solidly built than the stock oil filter attachment on my car. While installing this my stock piece decided that it had gone through too many heat cycles and snapped off. Now I can't even install this because there isn't anything for it to screw on to. I know as you are reading this that you're likely joking to yourself that I over torqued it. Well, I'm like 95 pounds soaking wet. So no, I didn't. What I would recommend (and what I ended up doing) is for you to is to not buy this, and instead buy a full block off plate, an oil cooler, and find a remote oil filter kit for a domestic that still uses 10AN lines, or whatever size AN lines your block off plate and oil cooler use. I found one for $110 shipped to my door. Really, aren't you tired of oil peeing down the side of your engine every oil change anyway? Don't buy this, but still buy from FRSport because they're awesome.
