Next is out to the truck to pick a location for the can. Billet Technology doesn't make a kit specifically for the JK so I purchased their "fender mount" kit which has the swivel and bolt. I figure it will afford me the most options. Also, most catch cans are attached to the engine somewhere near the intake. It's OK to do this but there is a better practice. It is best to mount a catch can as far from heat as possible so that vapors will condense on the way to the can. If you put the can in a really hot location more oil may stay in the gasses. I know that the real difference in temperature under the hood is probably one degree or two but I'm going to try to be as picky as I can.
