I THE GREAT
Why dont you ring holden spare parts, or a holden wreckers for air box? I got a Fram air hog (same sort of thing as K&N) on special at super cheap for around $45. K&N usually around $100 form memory.
DUnno why you wouldnt just mod your box, I have the two hole mod + MCAI and am not planning on going back, waste of money to buy a second airbox you may never use
I still have a few months of factory warranty left..if something goes wrong I dont want holden to make excuse that I hacked the airbox and thats the reason...
