So the KnN will let more air in to the mixture even if its in the airbox i ask because the people on 400 greybike forum say if its in the airbox it wont let more air in but wat would be the point
Paper filter restricts airflow when you put a k&n&n in you can even hear the air being sucked in but if you have no performance mods it's pointless Sent from my C6903 using Tapatalk
All the K&N does is allow air to flow better, which means if you have bigger jets it will cope better. The engine will only draw the air it needs. I would be looking at the carbs if it's bogging down.
