1. Consistent large gap.

 

2. Small electrodes that don't block the flame.

 

3. Great spark exposure to F/A mix (see 2).

 

4. Electrodes don't wear.

 

5. Great endurance.

 

6. Can you go wrong with a well designed moped plug? Nah!

 

7. Cheap - merely US$ 11 per plug (I use Denso IK27 with my Light Speed Eng. EI).

 

SOLD!

 

Thanks Grayhawk
