So, we've had numerous days the past few weeks in the 90s, today was 97. I took the Jeep to fill her up with gas, and then went home. She sat for 2 hours, I went out to check the oil, and before I popped the hood I realized it was REALLY HOT under there. Upon opening up the Jeep, I touched my intake pipe and it was SUPER HOT.


Any ideas? I mean the car runs fine, its not overheating at all, but for some reason in this extreme heat, the engine bay is holding it, even hours after it being turned off.

I removed the engine bay liner and took it for a drive, it seemed to help, but I don't know if its safe to leave that off?

Meh......that's what engines do. My YJ throws heat out of the engine bay like nobody's buisness.

I can't see any safety issues with the liner removed, but I don't know if the heat would start to effect your paint over time. I doubt it though, it's really just
a sound deadener as far as I know.

Yea, I'll leave the liner out for now. Normally I wouldn't be concerned, but it had sat for 2 hours, then I popped the hood and nearly burnt my hand on the intake pipe. It was HOT HOT HOT.

Yeah, the YJ is like that. Sometimes I can walk by my YJ after 2 hours and still feel the heat! lol

Unless you start seeing changes in performance or other little oddities.....I wouldn't be too concerned about it.

Its going to be hot under the hood. Especially with your A/C running etc, temps will be 200*+. Thats why its so silly to see people with those cone filters exposed to the underhood air. All they have done is make it louder sounding, but thrown horsepower out the door, due to hot air being drawn in.

Keep in mind, they design these things to handle bitter cold, or the extreme heat we encounter in the lower 48 states. There will be far hotter temps in texas-arizona, and people leave the insulation on. Some vehicles need it on there to protect the hood from excessive temps, and paint damage, hence some have them, some dont.

Let's see the test results,shouldn't be no problem to show your test data from the dyno and copies of the IAT temps before and after switching intake systems.That being you actually verified what you wrote.

To the OP
Yes it gets hot and the reason several of us have installed hood louvers to have more area for the heat to escape

As usual, the problem with this thought process is, you haven't fully duplicated real life conditions if you used a dyno, and thats about the only way you are going to generate numbers to prove one way or the other. Reason being, you are not driving around town, with your a/c on, or whatever, going for 20min or longer, and while idling in the sun, locking it down on a dyno, and conducting a dyno pull. Unless you are fully replicating conditions 100%, any "tests" you conducted are like cold fusion.

What are hood louvers?


To update this thread, I removed the lining as mentioned and took the Jeep on a 50 mile trip this morning. My engine bay temps were much reduced and my intake air temp(I have an Ultra Gauge monitoring various temps), was nearly identical to the temperate outside instead of being 15+ degrees hotter then it normally was.


I popped the hood at the end of the drive too, and the intake tube was warm, but not hot hot like yesterday. Its currently 94 degrees here, so slightly cooler then yesterday but not much.

The black things on the hood.



And yes they are functional.
