The picture above is of two different brand engine air filters. One is a Fram Extra Guard and the other is the KAX filter, which costs half as much. Can you tell which one is the cheaper KAX filter? There may be a difference in material that is not visible, but they feel and look the same. It seems like a safe bet to try out the KAX and see how well it performs/lasts.

Just Right

Fits just right. The paper filter material seems to be the same quality as the brand name filter I took out with the only percievable difference is price and packaging. One nice thing here is that once taken out of the box, the filter is wrapped in light weight plastic so you don't get the new filter dirty when taking out the old one. Just unwrap it prior to installation for a clean install. Hope this helps.

Same Quality, Cheaper Price!

Fits exactly as it should (2018 Acura RDX) and performs as well as any other brand I've used over the years. Construction and material quality appear as good as (or better) than any other off-the-shelf brand. I have no qualms about using this brand in the future and saving money doing so, compared to other brands.

Worked in RDX 2nd gen

It fit perfect in RDX 2nd gen. The filter built quality looks pretty much like OEM or better. I do not see any performance issue. Price was reasonable. Its a good buy.
