Airaid Mit In Contact With Radiator Hose

peterarch · April 16, 2010

I just got my Airaid MIT yesterday for my 08 silverado and put it on last night. The problem I came across tho is that the tube is coming in contact with one of the radiator hoses. Does anyone else here have the MIT installed on their truck and does it come in contact with the radiator hose or not? And if it did does anyone have a solution to this? I tried searching the forum but didnt see any other topics on this problem. Ill try to get some pics up of it later

Very popular mod, yet no complain about it sitting on the radiator hose. Sorry don't have it.

Do you recommend it, what did you like about it?

Yeah, when I installed mine 2-3 weeks ago the hose & the MIT were pressed together pretty hard. Over time the hose will bend like it supposed to & fit in proper place. Hard to tell in pic below but the gap is now about 1/8". Just readjust yours every few days and eventually it fits correctly with a gap...

I put high temp insulation used to wrap chimney liners between the two.

Not sure if it does much but I didn't like the fact that my CAI was touching a hot radiator hose.

Well ive only had it on for less then 24 hours but it does seem to make a little noticible improvement in acceleration. What I like a lot right now is it definately changes the tone of the exhaust when accelerating over 1500 rmps also.

Yeaa i think im gonna take both of your suggestions, even with an 1/8" gap, I definately would still feel better with some temp insulation inbetween the two

Bad news that it presses hard on a very hot hose!, I am curious about the design of such a simple thing, can't Airaid do a bitter job?!

I will try a filter that flows better than stock! and see how things go.

That is the first thing I noticed when I installed mine. It is a poor design that's for sure.

Right!

Also, IAT will be read and fed to the computer before air is heated by the radiator hose. I think it would be ok in cold/freezing climate, but in a hot climate the IAT is reading hot already, the result is FALSE reading!

However, the stock baffles going over the engine heat the air after IAT, therefore in a hot climate, the end result is same except the aftermarket is giving you more sound!

Extending that logic, everyone should do the throttle body coolant bypass mod to stop running hot coolant through the throttle body. The way it is set up from the factory, everyone's throttle body is heated by hot coolant despite the initial intake temp reading. This mod makes sense for everyone in the Sun Belt.

Also, for the OP, there is an expensive retail product out there (Cool-Cover Intake Tube Wrap) that you could replicate as a DIY project.

Does the wrap fit the Airaid tube?, definitely will not fit the stock tube.

Tell us more about this. Do you have a link to a how-to thread?

A bad idea if you ever drive in near freezing temperatures. This could result in a frozen butterfly valve. Most throttle body heating systems use a thermost of sorts to control coolant flow thru the throttle body anyway. For example it would open under say 150°F and close above that temp. Once that air enters the intake it will exceed that temp anyways. The gains just are not worth the risk IMO.

Hence my endorsement of the mod for those in the Sun Belt. But you will find people on the Z71Tahoe-Suburban.com forum as far north as Chicago running this 365 days/year with zero problems, including the principal moderator of that forum who is in Chicago.

I too just installed the airaid and have the same issue, but also noticed a rattle at high rpm's that I didn't have before. Have double checked alll connections and everything is tight. Beginning to wonder if it is the tube rattling against the radiator hose. Will wrap it in some insulation to see if that will help.
