where did you mount it and are they worth it..?

most mount it between the intercooler and the radiator, and yes they're worth it.

nice... my intercooler is almost hard up against radiator, but im going to try it behind the grill..

I've got a process west stg1 intercooler and it fits between the intercooler and a/c condenser.. if its mounted up the top, as down the bottom the cooler gets very close to the condenser.

But at first I mounted it in the drivers side of the front bumper and had a thermo fan attached to it.

Mine is fitted the same as Kissy's but without a thermo fan. Car doesn't seem to get any hotter and I assume there is air flow through the fog light.

Its always a good idea to have a Transmission cooler if your using your car for towing purposes or even if you have a high powered T.

Anyways, I also had my PWR Heavy Duty T/Cooler installed in between the A/C Condenser and the IC but later got it mounted on the drivers side,

just like kissy has above. ^^

mounted mine behind the rhs spot light with a fan!

I have a heavy duty one mounted up behind the left rear wheel ,there is a large open area there plenty of room to mount with a thermo fan ,costs a little more to run the braided lines to the back ,but it is in a nice open spot with no airflow restrictions

My transcooler was fitted when I had my C9 built. Its between the radiator and the intercooler.
