K&N High-Flow Original Lifetime Engine Air Filter: High Performance, Premium, Washable, Replacement Filter: Compatible with 2021 Ford Bronco, E-0634

This is a quality filter and really is a huge step up from the OEM filter. I live in an agricultural area that has a lot of dust, and quit a few unpaved rural roads. So, I need to change out filters frequently. This filter will pay for itself rather quickly. I had no issue with fitment as some have had. It looks like K&N has resolved those issues. I have used K&N products for almost 30 years and fi d that they are a quality focused company that produces great products for reasonable prices.

Installed the product a few weeks ago and saw an improvement in gas mileage right away. It has changed over the weeks, but seeing about 1.5- 2 mpg improvement. Installation was extremely easy and just a few tools to complete. Fit easily and quality product. Definitely would recommend for the price.

This air filter comes in a beautiful red and fits perfectly into the OEM filter box. It has not only transformed my 15mpg 2.7L Bronco into a veritable Braptor that sips fuel like a Mach-E, but it also supplies me with witty pickup lines for The Ladies.™ It hasn't just made my Bronco a better truck, it....it's made me into a better person.

Trusting in the K & N brand. First non-oiled filter purchase. Time shall tell, but I’m optimistic. A good replacement for my 23 Bronco.

Easy installation. Direct replacement for the stock Ford engine air filter. K & N air filters are economical. Instead of throwing the filter away, clean it and reinstall it. They last for years.

My new 2024 Bronco was getting about 14.7 mpg when I bought it. I know what I am about to say may seem crazy but it is true. I watched a few YouTube videos that said the K&N filter actually improved gas mileage on their Broncos. I didn’t care about gas mileage but I do enjoy the peppier HP gain you get from this filter. So for performance reasons I bought it. My Bronco definitely feels healthier and more peppy while on the thottle. But let me tell you this. My gas mileage actually went up to 16.9 mpg. That was actually pretty surprising. That gas mileage is with me driving my Bronco with the four on the pedal all the time. So someone that drives more conservatively may get 18 to 19 mpg out of theirs. Mine is a 2024 Wildtrak Bronco. Mine is geared very low so a regular Bronco should get even better MPG.

Got this for my 2021 Ford Bronco 2.3L. Fit like a glove and install was 5 mins. Does not feel like there’s a difference but I’m sure it’s doing a bit better hp and mpg wise. Not sure why other posts saying it’s a loose fit. The stock filter sits the same way there is no clamps holding this on. It just slips on.

K&N filters have a impeccable reputation Good stuff

This filter is exactly what I needed. It fits perfectly easy to install all of about 15 minutes and that includes cleaning the air box.

Exactement comme prévu
