Uni Filter Air Box Vents

yes. but if i were you i would just remove the airbox lid. unless you do a lot of mudding, then you might injest mud, in which case i would go with an outerwears airbox lid kit off ebay. makes a big difference, you would need to go to i believe a 310 jet. i don't even know if it will run with a stock jet without the lid, let alone run good and not blow up.
 
I think a 310 is to big for just a new airfilter becauss I have a F7 pipe and no airbox lid and I run a 290
 
i think thats what the jet kit calls for. altho it may be only 280, i can't remember now that i think of it. but any way you look at it he's gonna have to rejet.
