Air Filter Maintenance: K&N Launches Filter for 2021-2022 Bronco


By Dusty Rhodes

For the last year, I’ve had the pleasure of looking after the fleet at each of the four Bronco Off-Roadeo locations. The advantage to this position –– other than working with Broncos in beautiful locations –– is that I get a front-row seat to maintenance requirements and wear items. As you would expect, the Off-Roadeo units fall into what Ford calls the “Severe Duty Schedule” due to the amount of time they are being subjected to use in dusty/sandy environments.

As a result, the most frequently serviced item on all our Off-Roadeo units is the air filter. It will come as no surprise that Moab units are the hardest on filters, but we’ve also had to closely monitor the units in Las Vegas and Texas. This is nothing new to owners of the 2021 Bronco and has been the topic of much discussion in the forums.

K&N Reusable Filter

K&N air filter for the 2021-2022 Ford Bronco

While touring SEMA a couple of months ago, I had the opportunity to speak to the team at K&N Filters about an alternative to the stock Motorcraft throwaway filter. Days ago, their national account manager shared the good news that K&N has launched a filter for the 2021-2022 Bronco. As you’d expect, the all-new K&N filter for the new Bronco is both washable and more expensive. At $75 retail, the K&N is approximately six times more expensive than a replacement filter from Rock Auto, but at 1,500 miles a filter change, it won’t take long to earn our investment back.

If you are interested in replacing your stock filter with the new K&N filter for both the 2.3L and 2.7L 2021 Bronco, the part number is E-0634 and can be purchased from CJ Pony Parts.

See you off road!

Will you be upgrading to a washable, reusable air filter? Let us know in the forums!



    1. I’m thinking that “1,500” was a mis-print, should have read “15,000 miles”. At 1,500 mile intervals, that would mean you’re changing the stock air filter 2-3 times between oil changes… doesn’t make sense.

    2. Dusty was referring to changing them in the Off-Roadeo units, which are indeed silty and dust-ridden! This is the “severe duty schedule.”

  1. Check out the Roush cold air filter kit it comes with a filter and a pre-filter as well as the cool routes see through cover so you don’t have to remove the cover to inspect the filter element

    1. Not a misprint, but thank you for being curious! Dusty was referring to changing them in the Off-Roadeo units, which fall under the “severe duty schedule” for maintenance.

    2. I checked out the Roush, and watched Lethal Performance’s vid on the install. But $75 for the K&N vs $429 for the Roush? I mean the Roush does have the bigger oval shaped element allowing for a bit more air flow, and the plastic see through top is cool, just seems kinda pricey for what you get. As a point of reference, I just sold my 6.2 whipple-charged F250, I was running the K&N cold air kit, came with filter, metal housing with gasket (that mated up perfectly to my Cervini hood, and the aluminum pipe from the filter box to the TB – I paid somewhere around $350 for all. What I may do to my Bronco, is dremel a square hole in the stock air box cover and panel bond some clear acrylic to the underside (maybe add some stainless pop-rivets to make it look tough). The I’ll have the “K&N” version of the Roush for around ~$80 🙂
