MJ, not sure where you got the $200 figure, I organised the group buy, and they're $160 delivered from Perth.
Jimbo, I went from standard airbox with K&N panel filter to Apexi dual funnel and CAI box. Definitely seems more responsive, love the sound, the box itself doesn't heat up much at... If you're after insulation stuff, I just went onto a building site and asked the guys for a metre or so of that insulation stuff they use in walls. Used race tape to really seal the box up nice and tight.
I bought some of that worm like plastic piping that bends (? what it's called) which was $10. Hear of other people just using drain pipe too! Gonna make some sort of bracket up for the end that sits inside the box and make something up to fit my front bar so I get direct air feed.
Nice mod to do, as you dress up your engine bay, healthier for your engine and you would have to get a few extra kilowatts out of this mod.
