You don't have to put the air filter back on, but you will have to richen your carbs, due to more air flow. You should not have to get a bigger battery. The stock size battery will work fine and then you can use your stock air box. Who told you that you need a bigger battery for your starter?

the Mk3's just need the 4 brush starter upgrade not a bigger battery,
but often times the battery cables going to the starter and ground cable are too small.

^^^Yup. Without the upgrade to the starter, its just 15 lbs of useless crap.
