K&N efficiency now stated as 98% 30 microns
- Thread starter Chevyc10

Similar to the multitude of other brands made by the same manufacturer.
I personally think it pales in comparison.
For example the Fram "Ultra" oil filter has Multi-pass Efficiency - ISO 4548-12 test - 99.6% @20um.

Decent efficiency for a jobber filter priced like a jobber filter, not for jobber guts in a can with a gimmick nut from a conniving marketing company that's priced like a premium filter.
99/999% will never see a speck of benefirs from the oil filter they chose. As long as the oil filter doesn't fail all are good to go. . The air filter is the most important filter . Changing the oil on a regular basis and a sealed air intake plumbing is the secret
aint this the truth.^
wot?

I'd say it works about as well as the K&N air filter, i.e. it's better than nothing.
Seems to be no shortage of filters that will do 20mu at 99%.
I would say maybe use it in cold climates to get that oil going through the filter rather than through the bypass sooner.

Agreed.
I 100% would take a puralator or wix air filter with no intake leaks and a mobil1 oil filter over say something like a k&n knockoff air filter with the best oil filter setup money can buy.
Talking about oil filters, not air filters.
Not between that small efficiency difference, but there will be a long term wear difference between a 99% @ 20u vs 99% @ 40u filter. And as discssed many times, that also depends on how long the OCI is. The longer the OCI, the more a high efficiency oil filter will benifit in reducing wear due to dirty oil. If you changed the oil every 500 miles you might not even need an oil filter. Change the oil every 10K-12K miles, and a high efficiency oil filter will reduce the wear due to particulate in the oil. Nobody can claim that dirtier oil doesn't result in more engine wear ... I'm still waiting for that official study to be posted on BITOG, lol.
That's true for every part on a vehicle ... the most important thing is that it doesn't fail.
Read up on all the million mile vehicles that are occasionally posted here and on social media etc. I haven't seen any of them touting the higher end oil filters being used.Not between that small efficiency difference, but there will be a long term wear difference between a 99% @ 20u vs 99% @ 40u filter.

Read up on some official oil cleanliness vs engine wear studies. Every one of them concludes that higher oil filtration results in less engine wear. Nobody has proven anything different.
How do you know exactly what their complete detailed maintenance records were? Maybe they were doing relatively shore OCIs, or could have been using relatively efficient oil filters (anything 95% @ 20u or better). People hear that a vehicle made it to a million miles and automatically assume they used low end oil and filters the whole time, and did 15K mile oil changes, so in their mind nothing better than that must not make a difference. Kind of like people say their engine didn't "blow-up", so what they use to maintain it must be doing a "good job", lol.
The k&n oil filter is high flow. The efficiency is passable but not a selling point.
What is the flow rate?
There is no such thing as a "high-flow" oil filter, in any oiling system the oil filter represents only a small restriction in the whole system, just as much oil will flow through any competently made filter as the next with a minimal effect on the whole oiling system, the K&N oil filter is just a cheap jobber filter with a gimmick nut welded onto it sold at a heavily inflated price to people who fall for the marketing trap.
