EFI Swap Air Filter

[Killer Frogs]

I'm about to drop my EFI engine from a '99 Explorer in the Bronco. I think I have most everything figured out except the air filter. What filter are people using? I'm going to mount it on the passenger fender. I know I want the cone style. A part number for K&N, Airaid, or another recommended brand would be great.

Do Not buy anything that has oil on it.. Dry only.

Why? Because when you clean it, too much oil always ends up on it, and then it gets sucked into the motor, specifically the Mass air meter.

Seriously consider an air box and drawing the air from outside the engine compartment.
Hot air costs you power.

I use AEM dry filters short & kinda oval shaped.

I have considered the air box, but I already made the choice of the hood without the vents. I think I am going to move the battery and put the air filter where it can draw more from the front of the Bronco, similar to what 904Bronco did.

Thanks

I've had a K&N for 15+ years and in front of a mass air meter for 7 years and have never had one problem. You don't soak it in oil after cleaning. Just barely coat it. My upper plenum is a '94-'95 Mustang so it turns forward toward the passenger side. Moved battery to driver's side and filter is where battery was. If you decide on a K&N just get on their web site and plug in the dimensions you need and it'll come up with a filter number.

I bought this for my 5.0 swap.

Then I bought a nice K&N filter. This one fits right on the end. I found a lot of mustang guys were using them.

I hope that helps

Been very impressed with AFE.

Looking at what 904Bronco has I was thinking it wouldn't take much to enclose that and draw the air all from the outside.

Another vote for AEM. No issues at all.

I run a K&N filter. Playing in the desert with the silt and sand, I rather have an oil treated filter. Just my preference. I've never had an issue with it fouling the Mass Air meter. As jw0747 said, it's not soaked in oil. As for it being in an air box, I don't really see the need, other than it acting as a pre cleaner. Loss of power from hot air into the intake? Under an extreme load like towing, I could see how it could make a difference, but for everyday cruising and trail use, my motor just doesn't demand that kind of power, that the colder air difference would make. The air deflector is just cosmetic. The Mass Air only faults from the fan wash when the filter is not in place.

I will comment that this is my first dry filter. I have run K&N filters in many vehicles in the past with no issues whatsoever. As previously mentioned I believe it comes down to how much you oil it. It does not need to be soaked, just coated.

After finding grit stuck to the filter oil that eventually coated the inside of the air filter assembly on my dune buggy I tried everything to seal the assembly and stop the grit. Greased the filter sealing rings, rubber gasket under the wing nut, K&N oil, Bel-Ray filter oil, Kal-Guard filter oil, etc., etc., etc. Eventually conceded that the grit was going through the filter, it wasn't leaking.

Since then no oil wetted filters for me. On anything.
Years later I read the TSB or whatever it is that Cummins will not warranty any engine fitted with one. Enough said.

OEM FZJ-80 Land Cruiser filters are washable and use no oil. Their filter can is rather well suited to dirty environs and the element is easily big enough to support a 351W. Making one fit an EB with fender wells would likely be a job. Fortunately my Bronco doesn't have those.

I have personal experience with a KN filter fouling a mass air meter, which caused a lean AF mixture in my Fox Body Track Mustang... And a new motor was needed.
I sent the MA back to the manufacturer for it to re-calibrated... I had cleaned it, but they still said it was dirty. I have not run a wet filter in anything since.

Personal preference... It may work for others just fine.

Super hi-tech cone filter with ice cream pail for cold air awesomeness.

No inner fenders, big ass tires, lots of wheel spin - the ice cream pail keeps the crap off the filter, cheap - ugly - effective.

Bonus style points for not even taking the handle off the bucket. ;D

Haha - makes it easy to pull it out of the way. I can even put the cover on it for storage!

My Bronco works - it's no beauty queen....
