Air intake ?'s

On a strictly trail/mud truck where are most folks pulling in air. Im thinking of running a duct to the cab to pull cooler clean air. Under hood seems hot and more prone to dirt even with good baffels. The cab sound good until you run the numbers for the mass of air a 500+ in motor will suck through it at 6K. Is under the hood with a good filter best? RK

I ran two 4" pvc pipes into the cab. With big K&N cone filters. Seems to work good. I was afraid one wouldn't be enough. I'll get some pics this evening.

Pics would be nice. I have a bunch of old turbo plumbing fom OTR trucks out of a local salvage yard. It 5-6" OD. lots of nice bends to use int he fab of a duct.

I ran an in cab snorkel deal on my 81 F150/460. Got rid of the heater assemblie, Welded a flat plate to the fire wall with a 5" piece of exhaust pipe through it. Ran the filter right into the glove box. Worked well. With no filter it was noisy as open throttle lol.

Find a air cleaner off an old IDI 6.9-7.3, And plumb up that air to air tubing you sourced. I went with the flexible for now and the 12 to 1 comp 507 seems to like it.
