When do you need a spark plug gap?
When do you need a spark plug gap?
GM has experimented with different spark plug gaps since 1980. If your engine has 100% combustion, nothing can make that better. A high dynamic compression ratio or turbocharged engines require a tight spark plug gap and it requires a higher ignition voltage to jump a wide gap.
What should the gap be on a Denso spark plug?
Denso spark plugs for a 1983-1995 Chevrolet 4.3L V6 are pre-gapped at .035″ and do not require re-gapping. Each spark plug comes with a protective nylon sleeve on the threads to prevent damage to the tip during shipping and storage.
What is the pressure between the spark plug gap and ground electrode?
between the spark plug gap (center electrode and ground electrode). 2) Pressure in the combustion chamber at time of spark discharge – Depends on compression and aspiration of the engine. High compression engines and engines with forced induction have higher combustion chamber pressures at time of spark discharge.
Where is the spark plug gap on a champion?
For Champion spark plugs it is a little less logical and is as listed below: Spark plug gap is where spark plug spark discharge is designed to take place. On a conventional spark plug, it is the area between the center and the ground electrode.
How to find the right spark plug and gap?
Before doing any small engine repair or maintenance, be sure to check your manual for recommendations on specific parts numbers and safety precautions. Now that you’ve found the part you’d like to replace, you can use the chart below to identify the genuine Briggs & Stratton replacement spark plug and gap recommendation.

What are the symptoms of a narrow spark plug?
The symptoms of narrow gap include a noticeable (continuous) cylinder miss, hard starting if all the plugs have narrow gaps, rough idle and engine hesitation. A spark plug that does not fire, resulting from a narrow gap, will appear black or wet when inspected. The black or wet appearance indicates unburned fuel.
