These spark plugs came with an engine I am rebuilding. What are they and is there any benefit to this type of plug?

QUOTE(Superhawk996 @ Feb 8 2025, 11:58 AM)  It was a dumb aftermarket idea that never really panned out. Not aftermarket! I saw multi-electrode plugs FIRST in the late 70s on rotary engines. Singles will not work properly in that environment. As ignition strength increased in the late 80s Mazda changed to surface discharge and got rid of the electrodes all together. The next place I saw them regularly was in BMWs. "M"s often came with multi-electrodes from the get-go... The BMW stuff works fine with single electrodes. Both of these examples were years before the "Split -Fire" craziness. I'd start with normal plugs on a T4 |
