I keep reading this on this site: "derestrict your airbox and order Vectra C intake pipe and additional adapter pipe, part No's are somewhere on this site". I have tried searching but have found no mention of part numbers. Also - what is this adapter pipe?
Could someone please let me know the part number for these items please?
On another similar note, I keep reading about the BMC CDA for example "If you want the best IMO get the BMC CDA (do a search on here)". - But you can do 3 letter searches on this site . Could someone point me in the direction of some info on these (for info purposes as I do not plan to buy one).
