AIH delete??? More info please!!

I was noticing some pictures of some different engine bays and the air intake heater wasn't there one a few, but they run a boost line... By deleting the AIH, does that effect the cold start at all???
I live in Denver and it can get pretty cold here.. I haven't bothered with mine, but it does make sense for more airflow. Any help would be appreciated.
Thanks!

AIH

Not all models have them. It is in the intake Y pipe. Get a brass plug from the plumbing supply store and make sure it has a threaded hole in the middle. Then get a nipple that you can thread into it and put your boost line on. The #1 reason to get rid of your AIH is it has no effect on performance therefore you dont need it and it is a potential grenade for your engine if it ever comes apart and gets sucked into the motor.

Negative, you wont notice a thing. I would do it in a heartbeat if I were you.

Thanks, that's good to know. Because i haven't dropped my motor in yet and i have my Y-pipe handy, I'm going to take it into the hardware store and find a fitting that fits it and do that before the new one gets dropped in.
Appreciate all the help!

When you find the fitting, would you let all us know which thread and size? I can't really take the y-pipe off and goto the store...so your research will help out a lot of us that can't have any down time. (I was going to do the AIH delete when I did the turbo...but I forgot about it.)

So, I said i would post the threading size for the AIH delete when i found it. I bought a 1/2" brass fitting with a 1/4" in the middle for the vacuum line. As you can see with the pictures, you can use a vacuum line port or you can use a compression fitting. There are also a couple pictures of the two ways so you can get an idea of both. All for under 5 bucks! You can also reuse the copper washer that was on stock unit. I'm probably going to do that and put an O-ring on there as well. Hope that helps you guys!
