I have just installed a HTP TIP, 2xs SRI, Forge BPV and a hyptertech tune on my Gen1. Loving every second of it, definite increase in power so far even though there is lots of forums of people saying SRI will actually decrease performance.. Not in this case..
Wanting to know if:
A: An airbox is worth it, will the heat drop dramatically enough to notice any more improvements? What about in Summer. I'm in Sydney.
B: I cannot find 2xs airbox's anymore, apparently some were getting made but I'm yet to see any, how hard is it to make a corksport or similar fit? Has anyone done it? Wanting it also for legal reason, apparently I'm defect-able at present with no air box? Can anyone clarify?
Thanks in advance fellas!
