What should the gap be on Ford Spark Plugs?
Depending on the type of spark plug used, and the method used to re-gap them, the electrode may also be damaged. The ideal spark plug gap is printed on a sticker under the bonnet. If you used recommended NGK plugs, they would have been BPR5EY-11, with the -11 representing that they are already gaped to 1.1mm.
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.
What should the spark gap be on a motorcycle?
The rule of thumb for the spark plug gap on older engines is coil ignition 0.025 thou and magneto ignition 0.018 – 0.020 thou.Spark plugs are typically designed to have a spark gap which can be adjusted by the technician installing the spark plug, by the simple method of bending the ground electrode slightly…
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.
When do spark plugs need to be gapped?
The gap is the distance between the center and side electrodes, set so arcing occurs at the proper voltage that ignites the fuel and generates the combustion that makes the engine run.

What’s the best way to adjust a spark plug?
Use your spark plug gap tool to adjust the gap. Gently bend the ground electrode in to narrow the gap or bend it out to widen it. Be very careful when making adjustments. Don’t bend the electrode more than a few fractions of an inch. It is durable but isn’t designed to take a lot of pressure. Also, take care not to hit the center electrode.
