Strongest quality among Custom Air Filters
I've been using them on an FTR250 and an SR400 for about 25 years each.
If the diameter or length does not fit, I use a PVC Joint for plumbing or a Cap for a chair leg.
The carburetor and filter sides are close to the standard Size, so I can get by with what I have in Home center.
I have been using them for 25 years, but I have not used one pc. for 25 years, but several, and I remember that I have bought only 4 in total. The average distance used is about 30,000 km, and the longest one is over 50,000 km.
None of them have ever been damaged, but have been replaced because they are no longer clean enough, or because they have become noticeably deformed and unattractive. The reason for the impression that they are torn may be that they are deformed due to rough handling, hitting the legs, not using Motorcycle Covers, or being damaged by Brush or other means due to too frequent maintenance (←common).
Basically, it should be terribly durable and reliable.
With similar products from other companies, there are many problems such as the rubber of the joint part falling apart, the filter part collapsing, the cap coming off, and not being able to be regenerated, but K&N has none of these problems. Well, if you think about it normally, if the parts that inhale break, the worst thing that can happen is that they get into the port and break the Engine in an instant, so this level of reliability should be there.
The behavior in the rain is also exceptional, and if properly cared for and the right amount of oil is applied, the car can be driven in normal rain.
Although there is a lot of oil to play with, it seems that even if it does get in, it will just run down.
I think that these changes depend a lot on the angle of the Filter installation, but the protection in rainy days is a perfect balance.
With other companies' products, you won't be able to run anything but UNI systems at all.
And when I applied Oil to other companies' products, thinking that K&N's strength to water is due to Oil, it clogged to the fullest (I experienced it to the point of crying and throwing it away).
K&N is totally different fundamentally because it uses Cotton with quite exquisite gap on the premise of Oil application.
In racing, it is sometimes necessary to remove oil in order to increase intake efficiency to the maximum level, but in street, it is redundant because it only weakens dust collection and makes it difficult to remove dirt.
In general, there is nothing Negative about the Filter itself at all, but if I had to say something, I would say that the Cleaner is expensive.
I used to use Ata0Point wash as a substitute, but the ingredients have changed and it no longer comes off, so I use San-Esu.
Still, it does not remove more than OEMCleaner. It might be better to remove it with San-Esu and then finish it with OEM.

K & N trust Air filter
I used it for CB 1300sf and I used it for MAJESTY without hesitating because I am using it well.
Size was also abundant, so CustomBOX could be used without processing.
Cost performance was also adopted Point because it can be used for a long time if washed.

I think that the feeling of wearing actually changed intake sound slightly and I think Response got better.
Domestic and others Manufacturer's items are also good, but Red series

ReplaceKit (sold separately) (Cleaner&Oil) The
It is attractive to be able to use it for a long term. I am considering purchasing newly.
It is also attractive that various types of vehicles are lineuped. It costs a multiple of the domestic price, but its value is enough!
