You might come across one on ebay or check the for sale threads on here or CTRO. If you do go for the CAI, ignore the Hydrolock Horror Stories. For this to happen you would need to be in about 2 foot of standing water and by that time it would be coming in your doors, so hydrolock would be the least of your worries. Myself and other members on here have run them in all sorts of sh!tty weather with no issues at all. Obviously don't go driving at huge puddles on purpose, but you wouldn't do that in your new car anyway would you?:lol:
They are a good bit of kit and can give you near enough the same gains as the beloved Gruppe M, the noise is quite metallic and barks when the Vtec kicks in, which then turns to a howl the more you rev. It is an addictive sound though and you want to Vtec it a little more every time:lol:
