What is the best air filter element for performace? K&N or BMC and are they worth the price?
Good marketing will convince you of anything.
I stock the K&N & Pipercross in case you need one.
Everytime a thread like this pops up, maybe I need to stock a BMC just in case.
Well not actually, say you add the K&N and it allows more air flow (which a good filter should) and the bike shows more power, lets say 2 HP. If its a good filter and you had a good AFR with the stock filter, let's say 13.1:1 and with the high flow filter it goes leaner to 13.3:1...you will need to retune to 13.1:1 to get the best result which may be a HP or two...just food for thought. Thats why bikes should be tuned with the good filter not added later.I ordered the K&N online..it will be delivered today or tomorrow...When I do my dyno runs next week I am going to run with it and with factory filter...That will be the true test for the K&N...I cant speak for any of the others.
