Bronco Reusable Air Filter Options

[GI_Jo_Nathan]

I really wanted to go this route but when I reached out to them they said they don’t have a factory drop in option available for the Bronco so I’m still running OEMs.. did you go with an aftermarket air box or did you find one that works with the factory box?

That's weird.. This is what I'm running in the factory airbox.

Hi everyone,

I am debating my options for a reusable air filter. There are a few reusable options out now compared to when I was first researching years ago.

Here are 2 that I am looking at:

Magnum FLOW OE Replacement Air Filter w/ Pro GUARD 7 Media

Mishimoto Powerstack Air Filter, Ford Bronco 2.3L/2.7L 2021+, Dry Washable

I am currently using a K&N E-0634 that I picked up years ago which I usually find dust in the intake plumbing when removed for cleaning and re-oiling.

I saw a thread on the Mishimoto already here, but it didnt really cover off road applications. Throughout most of my research, everyone seems to end up recommending disposable paper filters. I like that the Mishimoto doesn't need to be re-oiled like the K&N and Magnum FLOW.

I apologize if there is already an existing thread for the Magnum FLOW, but I wasn't able to locate one. The Magnum FLOW has seven layers and advertises a 99.7% filtration rate, which is better than some paper filter options. I am strongly considering picking one up and using it, then swapping back to the K&N between cleanings when needed.

I use my Bronco as a DD and for some light to moderate off-roading in dusty environments. With the cost of decent disposable filters with an efficiency above 99% being around $20 and the recommendation to replace them every 12,000 miles or after an off-roading trip, it makes sense to me to consider reusable options.

With this, I am wondering if anyone has any off-roading experience with these filters and can share their recommendations.

Thank you!

I did a deep dive on air filters several years ago. What I found comparing " advertised filtration rate" between brands is actually difficult. When a manufacture sends out their filters for 3rd party ISO5011 testing the manufacture tells the testing facility what coarseness of particulate they want the testing facility to use in the testing. So without knowing what particulate the filter was being tested with you don't know if manufacture A's 99% filtration is actually better than manufacture B's 97%. Manufactures are very secretive and illusive when trying find out specifics so a legitimate comparison can be done. S&B was the most transparent and actually have info on their website on their ISO5011 testing and seem to be a decent filter. I will say though if you are concerned about the longevity of your engine paper filters are the best. Any oiled gauze filter that promotes "more air flow" is trash.

Over the life of the vehicle;
What dollar amount is saved over buying paper filters?

Nothing measurable to an extent it can be called value.

Sales brochure knowledge...isn't.

Buy a pre-filter.

None of those things are worth the cost or hassle. Most importantly, as you have noted, they filter poorly compared to a regular filter. That's a big problem, and not worth any of the claimed benefits.

Add in that if you screw up the oiling (not enough or too much) you can damage your engine, and it makes no sense to use them.

One thing you might consider instead is a prefilter for offroading. I've never used one, but have seen things like https://filterwears.com/ talked about a lot. Roush and other makers of aftermarket intakes/filter boxes also come with similar pre-filters, but that's a lot more $$$.

I just buy OE filters in bulk from Rock Auto (about $22/ea shipped for Ford filters for the 2.3L) and replace as needed.

Yea maybe paper filter with a pre filter mesh cover for offroading would be best. Even the non-oil ones look a little iffy filtration wise. I am trying to find more info on the Mishimoto one.

Why not consider a cold air intake with a dry reusable filter. Mishimoto makes a good one.

Thats one of the ones id like more info on off road use on. Alternative is the magnum flow which provides some info but real world use would be more informative.

If I was racing, where I wasn't worried about engine life, I'd run a K&N type filter for the higher flow. But since I tend to keep vehicles a very long time, I use a paper filter. There's an easy way to get more flow through a paper filter. Push the gas pedal down more. Unless you're running at wide open throttle all the time, the difference in air flow isn't a problem. The difference in filtration can be.

One other factor. A paper filter will keep your MAF cleaner which means it will be more accurate and last longer.
