Hello all, I replaced my coils, wires and plugs and I tried to diagnose my plugs. I looked online to see what the conditions of the plugs are in. The only info I was able to find was that my plugs are either normal, worn, or fouled. So I thought I would turn to the community to get an experts advice. Any useful info is highly appreciated.

Look pretty normal to me.
Maybe a bit red'ish .. would expect to see a bit lighter in colour.

Hard to say with camera .. and exposure and stuff

 

the typical analysis is not really valid on a rotary engine since they inherently run dirtier than a reciprocating piston engine

 

Can't exactly tell just by looking at them if they're good or not. Use a multimeter (?) to check if they're good or not.

 

Look OK...can't see the electrode tip on the second plug...but if it looks the same as the others your coils all are firing.

The plugs look typical of rotary plugs...they aren't oil or fuel fouled

Gaps look big...so they are worn out

 

the proper OE gap is large & wide by most standards, just installed a new set today on a RX8

standard: 0.046" - 0.049"

Max allowed leading: 0.059"
Max allowed trailing: 0.055"

 

thanks for the info
