has anyone removed that clear plastic cover from the AFE momentum? i was wondering if you get any more sound out of it by doing that

You may get some sound but you will also let a lot of hot air into the intake.

Disclaimer: I don't care.

Is the the air temp in the engine bay really a concern when that air is going to pass through your rather warm turbos on its way to the engine anyway?

Go for it if you don’t care. Underhood temps are hot in the St. As intake air temps rise the computer pulls timing and thus power. Same reason many of us put a bigger intercooler as intake heat kills engine power.

I get the downside of higher intake temps...but what I'm asking is does air from the engine bay really matter considering the heat from the turbos? Is the intake air temp sensor before or after the intercooler?

I have no intention of doing this mod, I'm just curious about the technical impact of doing so. I'm also not saying anything in this thread is right or wrong, I'm just asking a question.

I guess I was a little grumpy when I asked the first time but the "I don't care" part was in reference to the fact that so many simple questions get turned into a pissing match around here. Call it pessimistic anticipation.

No worries. Added heat is added heat imo. Another 30 degrees in air temp means at least 30 degrees through the turbos. The intercooler efficiency can only take so much heat out. I have no science available to prove it on an ST. However in my supercharged CTSV, the under hood temps were close to 200 degrees. I tested an open filter and IATs went through the roof pretty quickly and was a dog performance wise.

Understood, and thanks for the additional context! 200* under the hood is a lot higher than I would have thought!

Remove the under-hood insulation. I removed mine and noticed a 12 to 15 degree drop in intake temps! As stated by my SCT tuner gauge for what its worth.

The air intake temp sensor is on the air intake. If you've ever changed your own air filter, it's right there, you gotta unplug it.

Heat introduced by the turbos is due to compressing the air, not necessarily from the temperature of the turbos themselves. The intercooler negates that temperature increase.

Hot air in means hotter air out and depending on IC efficiency it may not negate all of it.

Like clockwork, you can set your watch to it ;).

Just an overly generalized explanation, of course.

Don’t post incorrect info and I won’t post to clarify it. Pretty simple….”overly generalized” statements can be interpreted as fact. I’m guilty of it myself but as I’ve learned there’s a LOT of people with little to no experience modding cars here I’ve tried to be more specific.
