I use the AEM. I have the model that has the IAT relocation hole in the end. The idea is that with the IAT relocated there,from the intake manifold, the sensor gets a cooler temp reading and it causes the computer to richen the A/F ratio a little. It may also bump the timing up a degree or two. Dino's Cherokee page has good home-brew cold air info. So does GoJeep. I'm using a cross of a K&N tube with an AEM filter. I'm gonna' try and use some heat reflecting/insulating tape around the tube and then use something like adhesive backed reflective sheeting to wrap around the "heat shield" that come with the K&N kit. Realistically, you get as much, if not more, heat coming in through these "cold air" intakes. Greater flow maybe, but it's not seperated from the ambient engine heat enough. I think the things I described above along with hood vents or a cowl induction hood would be VERY beneficial. It'd get rid of the excessive heat these engine generate, if nothing else. That lets thing like batteries, sensors, etc... last longer. It would also get the heat away from the intake and with the air that's forced in to the engine compartment at road speed, maybe actually result in lower "TRUE" intake temps. Sorry that was so long wided.
