I just added a second air intake that goes into the air box lid, I used a abs 3 1/3 pipe, got it hot with a heat gun and mashed it flat, like a 1 1/2 inch tall - then I cut a hole in the top of the ari cleaner and tried to glue it in with abs glue (WARNING ABS WON'T STICK TO THE AIR BOX) I found some plastic two tube mix and glued it in. Then I connected it with a hose to infront of the battery with a second filter. Mike OB
