Hi all,
here something to read about the K&N myth:
Debunking the K&N Myth - Why OEM is Better : Nissan Articles

K&N is expert on marketing!
Reading their website EVERYTHING makes perfect sense and you can convince yourself just right - no problem! Did it myself!
After checking into the above mentioned sites - I woke up!
Okay - the K&N flows what? - 30% more??
When do you really need that flow? Maybe really at the very top of your powercurve - until then your OEM will flow just fine - it is made to flow enough to make that top power.
How many times to you really
need that top-end power??
Are you always revving to/past redline??
Once you find out that the airfilter is the
least restrictive part in your intake system - "30% better" becomes near meaningless:
How much better flow of the absolute restriction is 30% better on the 2-3% restriction the OEM filter causes?
Or said the other way around: With your K&N you have only 2.1% restriction instead the OEMs 3% ......
Then, if you read in detail: Your K&N
has to get quite dirty to even start some decent filtering - meaning, it needs dirt to plug up and so catch more dirt!
Last - how many OEM filters can you buy for one K&N?
Besides, IIRR you can clean the OEM to some degree too.....
Today, the only way to filter is to put restriction into dirts way (well, there is other means, but nothing that even would fit on a car, let alone a bike).
I'll go back to OEM and better filtered air...
