Q:
My question is whats the difference between a spark plug thats gapped at .040 and .045? Does one produce more power than the other?1 answer
CUSTOMER CARE
A:
The gap adjustment can be crucial to proper engine operation. A narrow gap may give too small and weak a spark to effectively ignite the fuel-air mixture, but the plug will almost always fire on each cycle. A gap that is too wide might prevent a spark from firing at all or may missfire at high speeds, but will usually have a spark that is strong for a clean burn. A spark which intermittently fails to ignite the fuel-air mixture may not be noticeable directly, but will show up as a reduction in the engine's power and fuel efficiency. An improper gap will effect your idle, cause fouling, ie; basically give you poor performance.Q:
