Hi Phoenix
In case Revo does not see this..drop him a PM. We just got the complete carbon airbox in for the x35. Still have to test run it before posting up. We may expand across the range.
I would love to get an original csl intake box, so if anyone is not happy with theirs I'll gladly help them ease their mind by taking real-real good care of it for them.
Its not that simple. The CSL uses Alpha N and the standard M3 uses a MAF. You will need all new software loaded onto your ecu to cater for Alpha N. It's not worth the time or money. Just look for a Delage unit which is carbon fibre and looks like the CSL intake but still uses the MAF. Just don't expect huge power gains because there isn't any
