Open air filter

[offroadohio]

What are folks running for an open air filter on a n/a 6.9?

I cant seem to find a "bolt on" kit.

As far as I know, no one is, and no one sells one. The most common mod to the aircleaner assembly is to cut off the "soup bowl" on the lid, and remove the air deflector on the base.

You could use an International filter if it will fit under the hood. It's probably twice as tall as the Ford filter.

I thought about doin that. Looks like you just confirmed what I should do.

hey if you want to run an open cleaner this is what i did on my 89 7.3 i went to Advanced Auto Parts and bought one of their 16 inch universal hot rod top and botom then i bought a 16in x 4 in K&N element for it and the only other things i neded was threded rod to replace stock bolt and a 3 inch wide pipe clamp to raise it up over the throtle assembly. if you have any questions feel free to ask i had my truck taken apart down to the frame so mabe i can help.

Do a search on "ghost tube" That is a nice way to do it.

When doing air filter mods, be careful! A very small amount of water injested into a diesel will stop a piston in its tracks, hole, bore, or something.

Very true, but I think many or even most air intake designs will be less prone to hydrolock than the Ford stocker.

I'm not sure what the '87 air cleaner looks like , but my old '92 factory air cleaner was built to deal with water. Even had a drain tube with a one way valve ( pinched flat rubber end ).

Those fancy open air filter and tube setups, are begging to suck water. I haven't yet heard directly of anyone with a truck sucking water, but I'
ve herd of plenty of diesel cars that went that route only to suck up a belly full of water from the rain gutters on the street and wind up with a full set of well ventilated pistons.
