4 Cylinder 8 spark plugs?

Asked by May 19, 2017 at 12:36 PM about the 1998 Mazda B-Series Pickup 2 Dr B2500 SE Standard Cab SB

Question type: General

I am learning how to fix up my car on my own and went to change the parks
plug wires on my 4 cylinder engine, and noticed there are 8 spark plugs. I was
just wondering why, if that is normal? What do the other 4 do?

All 8 plugs serve the same purpose, a few manufactures tried that to optimize spark for more power and fuel economy.

right, some models got the duel plug per cylinder engine. so 2 plugs per cylinder equals 8. So get the correct set of wires.

The four spark plugs on the driver's side are ignition spark plugs. The four on the passenger side spark during exhaust to attempt to completely ignite the combustibles in the exhaust.
