After installing our 2JR 3" catback and 2JR catted downpipe, I decided to do a couple runs with an intake. Now I dont think there is a true CAI available as all the ones I have found sit below the battery, behind the fans, in the engine bay. Not in the fender. What we uncovered is what I suspected. In front of the car were 2, 1hp fans (floor driers). These move a ton of air and would probably simulate a 30-40mph drive. At any rate - here are the results: 2JR 3" Catback 2JR Catted Downpipe OEM Intake Box, with K&N drop in filter RUN 13 - COBB AP, 93 OCT map Run 15 - removed OEM Intake Box, added CAI - First Run Notice there was no change in hp or tq. Now, after RUN 15, which was the first run with the CAI. The intake temps shot up to 140deg. This is because of the intense heat that is in the engine bay. Immediately the power started to drop off. Our last run was 189whp. The TQ increase is with the CAI is only right at tip in when the turbo hits. After that, there is no change. ^^ Check out the intake temps - max of 140deg. So then I decided to turn the CAI outside the engine bay and rerun the dyno. The intake temps stayed at 80deg or so and the HP returned to normal. Point being, a K&N Drop In not only makes the EXACT same power as a CAI, but its way more consistent in its power as it doesnt pull air from a hot engine. So unless you can run a CAI in the fender, or build a box for it, or think of some other way to run cold air to it (and protect from the elements). The stock box w K&N is the way to go.
