Well, I broke down and bought one yesterday, and installed it when I changed my oil this afternoon. It is a nice fit, but not perfect. I almost stripped the threads on the hole because the valve doesn't seem to be as tight as the regular plug bolt. After everything was done, the complete assembly with cap sticks out about an inch, and that gives about another inch to inch and a half room between the plug and exhaust y-pipe. I also put in the 0-W30 Mobile 1 Tri-synthetic. It does seem to run cooler. Before the idiot gauge needle would be above the "o" in normal. Now it just barely gets to the "n".
I'm impressed, but now I think I should have bought the aeroquip(sp) fitting. Well, there is always the next oil change.
