4 Cylinder 8 spark plugs?

Asked by Alex May 19, 2017 at 12:36 PM about the 1998 Mazda B-Series B2500 SE RWD

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.

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.

Stupid! Just a ridiculous concept...wasteful, expensive and un-necessary.
