Air intake question.

I'm really surprised they kept that on as it's more for carbureted engines that need warm air to open the choke quicker. I removed mine completely when i installed a CAI. Truck runs no different without it.

with heat going to it?

The hose isn’t connected yet

I was thinking about that but figured if it didn’t help in some way, GM wouldn’t have blown money on it...

I always thought they were just using up leftovers from the parts bin...lol

That is true too probably lol

It wont do anything unless there's heat going to it (the tube has to be on). All your doing now is sucking warmish air from the engine bay through that hole. And when they do fail they tend to fail closed or sucking hot air from the exhaust manifold 100% of the time. If it makes you feel better, get a correct new pipe from an auto parts store (1.5" not 2" like you already did) and drive it around for a while after the engine gets to normal operating temp, then quickly pop off the rubber boot connecting to the metal air filter housing and check if its open or not. If its pulling fresh air from the rubber boot side, your good to go. If not, completely bypass that thing and never look back.

Well junk yard was a success but if doesn’t open very much...

Unless is it not suppose to open all the way? The truck was at operating temp

That’s not open at all that’s the “shut” position. Just wire it open and leave it so it’s not restricting your airflow in. No harm.

They did serve a purpose (supposedly) to help the engine warm up faster on cold start and get off the closed loop computer programming. The effect is very little but I suppose it was enough at the time to help satisfy the epa and their requirements.

It’s roughly half open, I have seen it shut completely before
