i was told to remove the scoop snorkel thingy that comes off the top of my air filter box because it restricts so much air flow. i have removed the upward scoop and now it feels like at higher speeds the quad pulls harder and I'm thinking its because of more air being forced into the air box. has anyone ever done a ram air type of mod on top of just removing the snorkel bend? also i have a K&N Filter and instead of making a separate thread which I'm sure has already been created, which is better of a filter? K&N or a foam twinair type filter?
