I have been reading a little on coils from previous threads but they seem to be to do with modified cars etc. Is their a general rule of thumb for replacing coils and leads- this is for my 2004 NB SE - completely standard...
After I recovered from my initial heart attack at the quote from Mazda for two coil packs and four leads.. I wanted to know if anyone has replaced the OEM coils and leads with NGK coils and plugs and had any issues. I know it sounds like a really weird questions to ask but I don't want to replace them and find that there is some weird Mazda voltage thing that necessitates the use of OEM coils and leads?
also there is no future in this car being modified in the slightest

Cheers
Brad
