I consider it to be a good air filter. Its negative aspect, in my opinion, is that it easily clogs up with dust and does not allow the car to breathe properly due to the oil it has. It doesn't mean that it's not a good filter, personally I recommend it for purchase, it's a good choice, it just needs regular checking and cleaning, for example, every 5000 kilometers it's good to be checked. I also believe that a good choice is the oil-free air filters, which I found are also available in the market, and they are washable too, they just have better material for filtering without needing oil to trap the dust. They definitely need checking as well, but you don't have to deal with the oiling of the filter.

If not the best, one of the best for factory filter housing. It replaced a 5-year-old JR which had torn (possibly due to improper installation) in one corner and is only plastic around, while this one has metal. I don't believe it has any difference in performance compared to the JR at least in terms of sensation. Of course, in the first few days after the change, you feel some difference in sound and power, but I attribute it to the fact that one is new and the other is old.
