I've used Bosch, pero not familiar w/ its' code (FRXxxx) basta parang ganyan. Kung carb lancer mo (like '99-'00 GLX nameron pang nilabas), kahit di na resistorized yun, pero kung EFI recommended 'to. I think the SP code of NGK for lancer is BPR5E for EFI or BP5E (non-resistorized).

Or you can search on google for the cross-reference of each brand, there are tables given what are the counterparts of it.
