I have thought about doing this, yet everyone has been going to a BHAF and a platform to set it on. Then adding on a heat shield to protect from turbo heat.

well, I was thinking about making an air box out of aluminum or light gauge stainless so that that its easily removeable then add the heat shield and running ductwork directly to the front of the truck. Then all you would have to do is buy a big cone filter and your good to go

The hard part would be to get the piping to the front of the engine bay. The piping needs to be at least 4" in diameter in order to flow enough air for the engine and turbo.

Your engine is using about 6000 liters of air per minute at 2000 RPM, this is wiithout boost. That is a lot of air going through the engine.

I have a temperature probe on the BHAF and the temps compared to ambient are negligible.. In the summer with a trailer going up a hill you can see a 15* rise. The intercooler does it's job very well so I doubt a 15* rise is going to make any difference. In other words, I don't see the point of a CAI. Under normal driving its like 5* over. If ambient is under 32F I was seeing almost no difference between ambient.

ISX is right...

Then people in the frozen North are try to do what they can to plumb in warm air for the engine. I see it this way there is a windows of optimal performance ot be had from a Cummins engine. It up to you as a owner to measure and watch the different IAT temps and figure out what give you optimal power and MPG's. Like my rig is optimal at 100-140*F IAT temps. which happens to be roughly 60-100*F outside temperature. At this temperature I hit my high MPG numbers. So as for the CAI I'm actually looking for a WAI (Warm air Intake) when its...



Now its too cold...

I have a BHAF and don't have any kind of heat shield on mine and I tow a fair amount. The first BHAF I had only lasted about 120,000 miles. Even though it was dirty looking I bet I could have run it longer, but for the $50 it cost to replace it I figured what the heck.......

well this kind of makes sense. Im just wondering if it would be worth it to have the CAI in the summer and just cover the plumbing for the winter or should I not worry about it at all and just get a BHAF and be done with it?

I think that the BHAF will be the best option. Then is you think you need a heat shield, you can make one.
