I have been monitering my intake temps with the aeroforce and even though i have mine in the wheel well the temps jump 30+degrees when sitting still or even city driving... what do people use for some insulation im guessing the heat is just working its way into the pvc pipe and thats whats heating up the air? Should i seal up the triangle opening around where the pipe goes into the wheel well? If i wrap a bunch of tin foil around it would that do anything?

the crossover pipe is directly under the throttlebody, so that crossover heat the tb rightup... nothing you can do which is why I switched to a open cone setup instead of my bumper cai which had 2 nasty bend and 13 inches of tubing.now just this.

in a cai with a housing the iat is placed inside the box away from the intake pipe. maybe try placing your sensor inside the fenderwell, outside of the intake pipe.

Did you say PVC? That's not good. And tin foil around it won't do anything. I cut a hole in the bottom of my bumper in the corner and added a vent. Helps push the air into the filter. Maybe adding some thicker insulation around the tube would help. Help keep the heat off of it. Anything thin is a waste of time.

Do you need lower intake temps in city driving? No. Warmer air will actually get you better gas mileage.

I wouldn't move your IAT as ScottMPala suggests, you want it to see actual intake temps. Moving the IAT to somewhere colder than your actual intake temp will cause your car to run rich, wasting fuel.

Personally, I say leave it alone. If you're really set on the idea of lowering your intake temps, they sell header wrap, you could try wrapping your cai in that.

In the end, less intake restriction is more important than lower intake temps.

wrapping the crossover will most likely cause it to crack. if your going boosted then intercools Cool

I have a 2000* coated crossover if you would be interested in it? Thats really the only thing thatll help, I don't do much city driving in sit still traffic, so I don't get heat soaking, hence why I didn't install it

You can also try wrapping your CAI piping with some kind of thermal barrier. You can find something at the hardware store that'll do the trick. I'd stay away from anything foam though, because in my experiences foam+heat=fire.

Or if you wanna go a different route, you can make an intercooled air intake-
