Can too small of a spark plug gap cause misfire?
A: Ungapped spark plugs will cause misfires as the gap between the electrodes could be too small or too wide. The air/fuel mixture then may not ignite or ignite on the wrong stroke, which can cause misfires.
Where is the spark plug gap on a spark plug?
Spark Plug Gap – understanding the basics. 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 often should you change the spark plug gap?
The spark plug gap adjustment should not be changed more than 3 times and should not exceed .008″ in either direction. Excessive changing of the spark plug gap setting will result in weakening of the spark plug ground electrode and can lead to breakage. Also, the spark plug gap should never exceed .055″ unless pre-set by the manufacturer.
How big is the spark plug gap on a Promod Turbo?
Some applications such as ProMod turbo cars using M1 fuel frequently run a spark plug gap as small as .012″, even though they are equipped with some of the highest output ignition systems providing in excess of 60,000 Volts high current and high mJ power output.
What’s the difference between ground and centre spark plugs?
In order for a spark plug to work as it should, the gap between the ground and centre electrodes needs to be perfectly calibrated. By adjusting this distance you are sad to be ‘gapping your spark plugs’. With the aid of a feeler gauge and the following advice, this adjustment is certainly something that you can do yourself.
