DEI Wrapped aFe CAI

Not sure if this is the right sub-forum, but I thought I'd share today's project.

The aFe intake has an all metal tube and with all the chatter about heat soak, I thought, "Can trying something that may or may not help mitigate heat soak for $25 hurt?" Before installing the heat wrap, I took a temperature reading of my metal intake tube, which was freshly delivered home by my wife. It was over 150 degrees... And I had to let it cool before handling to wrap... Your intake should NOT be this hot...

I went ahead and wrapped my CAI tube with DEI's Titanium Exhaust Wrap. Its normally used for wrapping exhaust headers for keeping the heat within the pipes as opposed to radiating out into the engine bay. I figured why not use it to help prevent heat soak?... It has great reviews, and the newest stuff wraps dry and does not require and post wrapping silicone spray.

The stuff looks awesome, and if there is some benefit to be had I look forward to it.

Here are a couple pictures.

First picture shows the little black zip ties I first used to secure the end of the wrap...


I then drove the Jeep to Home Depot and got 2 stainless hose clamps...


Sorry for the pictures being out of focus, but it was dark and the flash didn't look good...

Re: DEI Wrapped aFe CAI

I will get a good measurement when i get it back from the dealer today. I started the Jeep when I was done and excited to drive it around but I forgot to plug the IAT sensor wire in so the CEL is on and wont go off... Hopefully just needs a little reset.

Ill take some better pics and temp readings when I get it back

Re: DEI Wrapped aFe CAI

After measuring a couple different times, in a couple different places, it looks like it is about a 20 degree difference...

Not to bad for 25 bucks!

Re: DEI Wrapped aFe CAI

is that worth it? Serious question. Is 20 degrees cooler enough to make a difference to have people start wrapping their intakes? Will the cooler temp help in any way?

Re: DEI Wrapped aFe CAI

if you are interested in "testing", you can wrap the same part with aluminum (tin) foil. It will deflect heat as well, not look as nice as DEI products, but good enough to run some tests.

I read your post and it reminded me that I had some left over DEI titanium wrap. So I wrapped my AFE intake also. I should of did a before and after but I didn't. All I know is: on my Diablo Trinity the ambient air temp was 30c and at idle in traffic it would climb to 63c. Once moving again it would drop to 43c.
