To those witht he JLT RAI- with 99-00 GT; our cars have a sensor, i assume its an air temp. sensor, and it's located on the intake hose for the stock intake..on the JLT- will i have to drill a hole to install that sensor? or is there already a spot for it?

 

you have to drill your own...its stupid but has to be done...just put it on the underside of the intake so it cant be seen...looks nice

 

How do i know what size to drill?

 

You'll figure it out, just make sure to get a hard rubber grommet that the IAT can snug into.
Use the grommet as a template

 

ahh OK. I see their site says to use a 3/4 spade bit, with the supplied grommet.

 

There ya go!

 

C&L already has the hole in their piece with the grommet for the IAT FWIW.

 

Edit: I misunderstood the question
