Suzuki 4WD Club of Victoria

Hi Guys

Looking for advise on what spark plugs to get. I've had my car over 5 years now and don't recall putting a new set in ever. Good maintenance?

I see there are many options and descriptions are rarely technical. what should I be looking for?

vehicle is a 1990 Sierra, GB13. Vitara carby. Extractors.

example options on sale:

I've always liked NGK. Their website says they are the world leader.

I've tended towards NGK. Actually pretty sure I just put NGK in the XR6 and I've just put NGK in the Sierra. They were $5.60 or something from Supercheap, and because Supercheap are incompetent, they put 5 in the box. Winning.

I've gone with the NGK ones. The original Suzuki sticker under the bonnet has this brand also.

NGK BP5ES is the spark plug model for anyone reading this at a later date. (other options on the sticker where Champion N8YC and ND W16EX-U)
