AFE stage 2 intake

[Ruger]

If the primary heat source of your intake tube is conduction of heat from the motor heads and plenum, the shield will not protect from that heat source. It would even retard its cooling.

As I understand it, conduction requires physical contact. There isn't any. The intake tube (factory or AIRAID) runs without touching anything from the airbox to the intake plenum at the throttle body. It is only the underhood ambient temperature that heats it.

Howdy Gang,

I am assuming Deinonychus may have meant convention versus conduction. But with that said, I would think the "insulation" would help to prevent heat transfer to the intake tube.

I am far from an expert regarding this topic.

Methinks you might mean convection - as in heat-driven circulation. In that case, yes, wrapping the intake tube with insulation will certainly mitigate heating. Unfortunately, there seems to be no good way to insulate the intake plenum at the throttle body.

Please pardon my ignorance of my own truck, but does the air plenum (after the throttle body) get hot, especially when the motor is turned off after a long running period. That is the heat conduction that I am referring.

I ask that, because my Dodge Magnum with an aluminum intake plenum (highly modded stroker motor) gets very hot via heat transferred by conduction from the heads, so much so, that it spidered the paint on my fiberglass hood, and deformed the top of the hood from excessive heat from the intake plenum when the motor is turned off. In turn, as soon as the motor quits sucking air into the intake the heat from the intake plenum conducts back through the intake tube.

The intake plenum on the Raptor is the rectangular plastic box between the throttle body and the intake hose. It lives just under the middle of the windshield. I would think that with the engine off and therefore with no intake air moving through it, it would become the same temperature as the air under the hood. I don't know what that might be, but a cheap experiment with a thermometer would answer the question.

I doubt the problem you have on your Magnum will surface on the Raptor for several reasons, most importantly that it's plastic rather than aluminum and it's the same arrangement used on a great many thousand Ford trucks. If it was a problem we'd already know about it, as would a lot of other Ford truck owners.

What filter is every buddy running on there afe stage 2?
Thoughts on prefilter as well?

Thinking about getting one with the CAI with pro dry. Maybe prefilter. But If I ever do come into some dusty/nasty air out there not to sure. Im mostly on the street/pavement as it is a DD. but Like I said when the day comes I wanna be prepaid Maybe keep the pre filter in glove box and throw it on? Thoughts?

The Pro Dry S will be good for moderate dust/dirt. Adding the pre-filter will be a good idea for very dusty conditions. I think you're on to something with your idea. If you want to go a step further you can also purchase the Donaldson Powercore filter which can be retrofitted to the aFe. In either case, I would add the lid to reduce the exposure the filter has under the hood. The lid is definitely recommended for dusty/wet conditions.

Yeah. If I were to get it I would definitely get the lid. Thanks for the feed back !!
