As someone else has said, you can't really just slap it on the intake due to the MAF sensor. Unfortunately, the tuning support for the Sportivo doesn't appear to be very strong at all so finding a Cold Air Intake kit in Australia is near impossible unless you want to pay big bucks. It seems the only place to get one for a semi-decent price at the moment is the States. So the model over there is the Matrix XRS, but i'm not sure how well things line up in our Rollas when it comes to the install. I got a quote from CES racing (Jan 2014) up in QLD for a CAI to my door in Melb and it was bang on AUD $600. Insane. I've been trawling around for a Simota CAI (part no. SIM-AN1CA-53) but can't seem to find one in Australia. I did get a quote of AUD $169 for the item from the Simota supplier, Australian Auto Accessories in Nunawading, but they are completely out of stock with an unknown date of getting more. Don't be tempted to buy the Simota kit that Vic Performance Parts has listed on ebay also because they are definitely out of stock as they just issued me with a refund. http://www.ebay.com.au/itm/Simota-Cold-Air-Inductiuon-Kit-to-suit-TOYOTA-COROLLA-ALTIS-1-8L-01-04-POLISHED-/330743008376?pt=AU_Car_Parts_Accessories&hash=item4d01d1cc78&_uhb=1
