haha!

Well, essentially, by opening up the standard airbox, cutting the sides off appropriately, fitting 12mm breathers to crankcase hoses, you are just allowing more airflow to the intake and stopping the restriction created by the stock airbox.

Also, with having my autotune, it should make up the difference for the extra airflow...

EDIT:

Can anyone confirm what size the breathers are on the Stage 3? Are they 12mm?

I guess the best way is to just check the hoses on mine... DuH!
