I was wondering if the VCM OTR CAI would fit my series 1 SV6 alloytec engine? I was after this intake but havent seemed to find any that would fit my car.

Unfortunately, the MACE/VCM OTR does not fit any Alloytec engines (unless it's a late MY09.5 VE Commodore, which runs a MAF Cartridge). The only OTR which would fit at this point in time is shown in the link below:
