CFM intake for 7.3
Just got the new Diesel power mag and found this www.cfmplus.com and thought you might be interested. I think it looks sweet. Doesn't have price yet.

The stickers will definitely add some more HP.

I can see the flow benefits being there, meaning it looks as if it should flow better. I think the stock unit does have room for improvement, and it looks like the CFM one has addressed that.
However, I'm not totally buying into the non-heat absorbing affects of the composite on the flowing air. How much heat can the air actually absorb from flowing through a smooth [relatively] intake? If anyone with AE get's one of these things, I'd be interested to see the MAT readings before and after install.

LOL. Every truck may be different, but every stock intake is not. Flow is flow, and a direct comparison between stock and theirs wouldn't be all that difficult to get done.
I've got a CFM intake elbow on my Cummins, and I will say I'm pleased with the product. Dyno tests by an aftermarket vendor (ie - non biased) showed the CMF to have the most gains out of any others out there. However, I still don't think any data exists from CFM on flow numbers.

), but what filter are you running?? BHAF? And what turbo?

Joe, my filter is the AFE version of the 6637 with one of Pete's covers. It's not the BHAF -- that filter is quite a bit bigger around and I don't have that much room. I think the AFE flows plenty though.
Turbo is an HTT (High Tech Turbo) 64/71/13 (64mm compressor wheel, 71mm turbine wheel, and a 13 cm exhaust housing - something like a .96 A/R), with a stainless steel turbine housing.

Gene, I understand the idea and can conceptually see how the thermal isolation would benefit. Since the stock intake is one piece of aluminum, and you know how good of a thermal conductor aluminum is, if the turbo outlet side heats it up one side of it (which it obviously does), it would make sense that the whole piece will be hot as well.
What I don't know is how much of that heat is actually transferred to the air that's flowing through it, especially at the CFM that the engine ingests the air. That's where I stumble in seeing the benefit.
