Air Intake Wrap, Is this stuff worth it? Options

[TRDDawg]

I have heard that the insulation or intake wrap lowers the temperature of the air in the intake by 15 degrees. Is this worth to buy? I think a kit costs $50. How much hp do you gain by using them on your intake?

Hi,

Any insulation that can reduce radient heat will help with HP.
The problem with radient heap swap or soak is that once she gets hot she usually stays that was unless you get some cold air flowing in and over.

Meaning if you are driving in traffic then heat swap will occur & takes longer to go away then form..(Unless you turn the engine off and let it cool.)
Thats why you always have this great power gain in the morning on a winter day....until eng heats up too much.

The other thing to consider is are you runnig a metal intake pipe from the inj manifold to the air filter.
A lot of after market models look great and come in many colours and shapes but radient heat from the engine creaps along the piping heating it up and the air that travels thru it.

I would recommend keep the rubber factory one if you can and wrap it in heat proof foil or foil tape..!
Also piss off any high flow exposed pods and put box back with a high flow filter, but run a 2.5 to 3 inch pipe(wrapped in foil) from under the car up and into the bottom of the air box to get flowing cold air thru the filter..insead of dead air from the side guard.

Cheers
