After market oil filter compatibility

I definitely prefer the K&N oil filters over any others and I don’t mind paying more for the quality!

Today, we are in the age where all major patents are expired, everyone is copying from everyone, and brand value has declined.
Today we measure the return on investment.
So today the price does not always say anything about the cost-benefit ratio.
In the age of social networking we are also much less naive, and the brand also suffers because the knowledge is no longer the domain of the big corporations, and the public has learned to check what is good for him, and not because the corporation does a “Research” and recommends its brand products.

The K&N filter can be great, but not because of the video you presented, nor because of the high price. And if a person with a lot of experience in the field(Mr' Danno) says that the filter is not recommended for racetracks,

K&N filters are pretty much banned by all racing organizations and track-day providers.

I am personally indifferent to quality, and not willing to pay more for a quality filter above the standard, but if the issue is very important to you...I would take that info into account, and ask more people about the quality of that filter, that's the power of social networks.

Things to know about an Oil Filter (And Aftermarket Parts):
1. All patents expired long long time ago. The parallel production is in quality of similar materials Vs' origine, because there is nothing to save there. The oil filter is built from a simple materials available and cheap for all. When it comes to new patent the pricing of the engineering development is entering into the new product price. Today there is no longer anything to develop in this component. It has reached to perfection.
2. Those who insist on paying more, pay mainly for "branding", it's a spin, just know that the extra money it's mostly for the "branding", because there are no quality differences that can be felt in them.
3. This is such a simple mechanical component, that it is easy to do a visual quality inspection for him, if It's look well built is good.
4. I personally use parts from parallel production wherever It possible, and when the price differences is Big. Or in the case of significantly improved parts, such as:
Steering roller-bearing.
OR (Another example): A manual tensioner for a timing chain that is built alone D.I.Y at 4USD and even less than that, when the original tensioner costs 30USD, when the manual tensioner is no less quality (advantages and disadvantages)

The CBR250R is a budget motorcycle, and it is most legitimate to save on him an expenses.

5. The black color of the used filter, it is the color of the burnt and spoiled oil that you replace, it is not a substance that the filter stopped, it is the color of the old oil. Harmful aluminum chips etc (such as those that may block the passage of oil, or do great damage to the bearings), are stopped by the strainer(the Screen Oil filter). The other particles that are trapped by the oil filter are: Sand and dust particles, and micron chips of metal as a result of natural abrasion. The generic filter easily stops them all.
The Screen Oil filter:

Whoever getting 120% from his engine on racetracks will invest in expensive upgrades and have fun. Those who ride calmly, and see at CBR250R motorcycle as a cruiser motorcycle (because sitting upright and very comfortable for this purpose), are usually at 5-7 rpm, for them, from me, it is usually a different story.

in case or K&N, design flaw was welded-on nut at end for easy removal. Many people do not realise is for removing only and use it to tighten filter. This accelerates cracking at nut due to heat of welding. Even without that added stress, regular heating/pressurising cycles causes filter to crack and spray oil onto hot exhaust headers. O-ring on filter also slips out due to oil-pressure.

I witnessed these 1st-hand:

2019 - trackday @ Thunderhill East with Trackdayz.com
K&N filter blows entering slowest turn-14. Rider crashes with 4 others behind him who hit oil spill. A brand-new Aprilia RSV4 is totalled. One rider broke both wrists

2020 - trackday @ Buttonwillow with Pacific Track Time
K&N filter blows at high-speed Riverside sweeper turn. Luckily rider was alone, crashes off-track and bike catches on fire from burning oil. Track is closed for 2,5-hrs for clean-up




I have not seen any 3rd-party independent tests showing K&N oil filters to be better than OEM ones. Many decades ago, 3rd-party study of cab & truck fleets using K&N air filters shows them to have worse filtering than OEM, resulting in more engine wear. This negated any cost-saving from reuseable filter.

Here's photos and more links of interest. You will not find similar failures and large number of complaints about any other filter.

The front nut in the N&K filter is not intended for tightening (only for removal).
Any filter that is tightened excessively, even without the nut in front, and It is very easy to tighten the oil filter excessively, any oil filter that is tightened incorrectly may fail, crack, and leak hard.
I have the impression that the publications on K&N are trending and related to unfair competition in the industry and not to objective coverage of failures in oil filters of all kinds as a result of over-tightening.

You are familiar with this tool, its use causes similar damage (allows easily to reach a state of over-tightening):


There is no way to prevent over-tightening of the oil filter, and the associated damage ( cracks and strong oil leaks).
No manufacturer has a defense mechanism(idiot proof mechanism) against that issues.

In the particular case of the oil filter in our model CBR250R, whoever Install it upside down will cause the oil passage to be blocked and the engine destroyed in a short time, without a single flush of oil leaking out.
It is impossible to completely avoid such mistakes, there will always be a negligent mechanic who does not understand what he is doing and will cause serious failures in a system that was fine.
All good, thanks for the google photos.
