Has anyone seen/used any barrel-style K&N filters on a 79-91 e150s? My application is a 1988 conversion model with an EFI 302. I'd like to use an aftermarket setup since the stock airbox (which wraps around and under the battery tray) is a pain to get around and just seems poorly "plumbed" and restrictive. All that K&N lists for the application is a quality replacement for the stock filter element, but it's the airbox itself that most frustrates me.

Ideally I'd like a system that ties into both of the manifold inlets and still has connections for the smog pump and oil system pressure release line. Perhaps something that rested on the driver's side (where the secondary battery option would normally fit) would be good, as it would provide a much straighter line and more cool air than the stock location.

Thoughts?

Look at the K&N 63-1067. It's for the F150, but it may work with a "little" modification.
Or it may just drop on in.
Haven't tried it myself, so I'm just guessing.

Hmmm, looks like it might work.

I've thought the same thing about my 91 351W, I think that they use the same intake setup as the 302.

My idea, although I've not tried it yet, was to run the intake hoses from a 92-96 F-150 v8, they have the same twin throttlebody setup as the vans, heck it's probably the same exact engine. In any case, if you've ever seen one, they have two intake tubes that run directly from the TB to the airbox, the plumbing is not quite as complicated / restrictive as the E-150. the K&N FIPK kit for the F-150's basically repaces the stock airbox with a dual outlet conical filter.

The only issues that I have with running the intake across the engine into the drivers side area of the engine compartement (next to the winshield washer reservior) is the fact that there are a few things in the way (A/C lines and the cruise control servo).

I think that the CC servo can be relocated a little for clearance.

The other problem is the auxillary tubes / hoses that enter the stock airbox setup. I have one that enters the first part of the intake above the battery, I think it is plumbed to the A.I.R. pump and forces air out whent the throttle is slightly opened. There is another hose that takes air in from above the filter on the airbox, I think it feeds the A.I.R. pump with filtered air. There is another hose the comes from the airbox to the oil fill tube (crankcase breather). The crankcase breather and A.I.R. pump feed would be an easy fix. But the tube that comes from the AIR pump may require a little more thought...

My guess was that Ford designed it this way to keep intake noise down. If you've ever been in a car with an aftermarket cold air intake, it is noticibly louder than stock.

 

Rustbucket --
K&N 63-1067 IS for dual throat throttle body. Look at the installation instructions.

 

There is also this one for "w/o mass air"

K&N # 63-1014

 

mule, how would you plumb it? I know what the filter looks like, I've seen it before, but would you suggest that you attach it directly to the TB?

 

I wouldn't attach it directly to the TB, as the filter may hit the fan.
