Seems like a good engine filter
Purchased the KAX Premium Engine Air Filter for my 2016 Ram 1500 Rebel with the 5.7L Hemi, and it fits perfectly—no complaints on fitment at all. Filters are filters, and this one feels solid and sturdy. Installation was quick and straightforward. I can’t comment on long-term reliability yet, but so far, everything looks good. If you’re looking for an easy drop-in replacement that fits without any issues, this is a solid choice. Would buy again based on first impression.

Good Value and protection
This was perfect fit for my 2022 Dodge Ram Classic V6. I did notice that the KAX was thicker than the big name brand that it replaced. This means a lot more surface area for filtering. The KAX fit my truck with a tight fit and no issues. I am very happy with this filter.

Increase in mpg
Great filter that compares to OEM. Bought this one for my 2020 ram 5.7 and it even increased my mpg. Overalls it's a good buy for the price.

Perfect fit for 2016 Ram bighorn 1500
Nothing to really do, take off your air filter cover and take out the old dirty filter, clean the inside if needed and put in the new one. Tada.
