My awesome wife who I always thought was just entertaining me when I showed her my tinkerings brought up a good point that deserves attention. Metal is a much better heat cunductor than plastic. Thus now when I touch the intake pipe its pretty damm hot which means the air inside is also pretty damm hot.

Since we are going for the every little bit counts here shouldn't we be getting these pipes coated to resist heat or use some of the heat wrap I see on headers to keep intake temps down???

It would be a good idea. It wouldn't hurt anything, so why not? Every little bit helps. When the ISR mod first came out, I tried to think of a way to rig up some kind of intercooler that would wrap around the pipe, and voila... instant cold air intake. It started getting too expensive so I scratched the idea.

Here's the discussion I was talking about

What a timely post!

I asked Dr. Z about these products JUST this morning:

To paraphrase, he said that he used to use the stuff on his car, but given that it was a turbo, the engine compartment temps were much higher.

The products _do_ work though... In the case of the above, it's a question of how much do you want to pay to reduce the temp in the engine compartment.

Just because the ISR piping is hot does not mean that the incoming air is hot. Its the source the air is drawn from that really matters. The velocity of the air is too fast for the "hot" ISR mod piping to make a difference.

Ever seen an AEM cold air intake? The pipe is ceramic coated, but it draws air from the fender well. That's where the majority of HP gain comes from.

I wrapped the entire intake on my 98 3.4L, and it did nothing. I say don't bother.

I agree, unless you have a turbo, its not really necessary.

One trick you can do though... if you want a couple extra brief HP, get a couple of ziploc bags full of ice and stick them on the ISR pipe to get it nice and frosty cold. Go for a drive and be amazed, and then sulk when the power disappears. :cry:

in an atempt to make sure i am getting fresh cool air i used my hole saw and punched a 3 inch hole through my airbox and fender so i can route an intake from the front valence into the airbox. after a short drive i stuck my hand through the hole and into the airbox and it was HOT!! about as hot as having the heater on full blast . There has to be a way to get these temps down.
