I like PBR, my buddy Earl drinks Miller. Anthony, he goes for Coors. Zap he likes Bud Light but only in bottles.
None of us agree on K&N filters either but we all wheel, camp and drink beer together.
You'll never get a simple or straight answer.
K&N opinions will vary as widely as which beer is best then it turns into to a snorkel discussion, then people start to argue and bicker over their experience with motorcycles, dust and desert racing. The mods eventually lock the whole thread as it simply spirals out of control and has nothing to do with your original question.
K&N was a thing back when engines didnt have all kinds of sensitive electronics and fuel and air was pumped in via carb.
stick with an OEM air filter. very educated people were paid lots of money to ensure that your engine doesnt need to be replaced prematurely, dont throw a filter on that will allow more junk into your engine for extremely minimal gains.
