Took all my stock intake crap out to make room for the intercooler piping, and put on a custom short ram intake. I had to reroute some hoses because there was a mini radiator in the intake. It made the air box hot as hell to.

What did you guys with CAIs do with it...I just took it off, and used one of the bigger hoses to go right from the water pump to the throttle body, and took everything else off...

If you do this tho, make sure to use the hose with the big brass coupling on it, cuz I think that might be a pressure regulator or something.

Oh, and if someone call tell me how to post a picture in the thread, I will put a pic of the thing up on here.

that is a small radiator and I think its only in the '99 and maybe '00 TL's. its in your manual if you want to read about it, its to warm up the intake air when its below like 25 degrees. Anyway, when you get a new intake, you just bypass it (connect the hoses together)

Oh ok...wasn't too sure...so then that little spring loaded flap opens up when the 25 degrees is hit?

ya pretty much, the exact number is in the manual...but thats the idea (warm the intake air!!!!!)

yea in the summer months its bad, but it helps the car in the winter. the 2000 and newer tls have the coolant routed thru the TB (most cars do) it has been shown to make a few hp in the summer on many cars when bypassed
