i'm not sure which year you've got, but if it's an 04+, it should just pop right up & out, but you'll need to open up the airbox & remove the pcm on the bottom before pulling the airbox out. i removed mine without disconnecting anything, put some rubber underneath & zip tied it down where the airbox used to sit. hope i don't have any problems with that...
anyway, my baby sounds a lot louder & feels better, but sometimes i hear some clicking or rattling from the engine while stepping on it... the filter isn't in contact with anything because i suspended it with a zip tie... any ideas what the noise could be?
