why do you want an ss reduction kit? it's just an overpriced piece of plastic. holden cai will do the trick, $60 new, or find one second hand. i paid $30 for an air box and a cai modified to suit a vp.
But your car can't get more air in At the end of the day, your car can only eat so much air - and it will get just as much from a Holden CAI, or a home made one. I just run a $20 black ribbed pipe from my airbox down to the front bumper - and I can guarantee you it can fit more air through than the SS CAI, and it gets colder air, too.
The SS Reductions CAI is a waste of money - for that price you could get a nice tyre
