### ⭐⭐⭐⭐⭐ Fits 6 gen Bronco
*by M***D on October 20, 2025*

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.
