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.

What happens if spark plugs are not gapped?
Spark plugs that are not gapped properly will cause the engine to either skip firing, or ignite too soon in the compression stroke. The gap between the center and side electrodes of a spark plug must be an exact distance; otherwise, your plugs don't fire efficiently. ...
Can you gap pre gapped spark plugs?
You need a feeler gauge to gap your spark plugs properly. Gap new as well as old spark plugs, even if the package says that the new plugs are “pre-gapped.” To avoid problems, work on only one plug at a time, in cylinder sequence order.
What are the tools that can use to check the gap to a spark plug?
A feeler gauge is made up of a collection of calibrated metal strips of varying thicknesses. The blades look like a pocket knife when joined together. It's the best tool for measuring and adjusting the spark plug spacing.
What is the recommended spark plug gap?
The gap setting is different for each vehicle but most are somewhere between 0.028" and . 060". Consult the owner's manual or Champion ® catalog to find the recommended setting for the vehicle you're working on.
Is a smaller spark plug gap better?
A smaller gap will yield a short, intense spark and will usually make the engine real responsive. ... So a small intense spark is much better than a big, weak spark, especially when dealing with richer fuel mixtures and more volumes of fuel being burned. A good starting point and pretty much the all around best gap is .
Are pre-gapped spark plugs good?
Autolite spark plugs traditionally leave the factory pre-gapped for their most popular application. However, a plug may fit hundreds of engines, from cars to golf carts. Gapping the plugs to your engine's specifications is important to prevent pre-ignition, detonation, fouling and poor fuel economy.
Why does my car shake after I changed the spark plugs?
Shaking or vibration may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faulty idle air control valve may cause the engine idle to drop below the normal idling RPM which may also cause the motor to shake or vibrate more than normal.
Do spark plugs increase horsepower?
In short, yes, in some situations spark plugs can increase horsepower. The theory behind spark plugs increasing horsepower is that by providing more spark to the firing tip of the spark plug, it will (and does) combust more fuel. ...
Do NGK Iridium plugs need to be gapped?
In most cases your Iridium Power plugs do not need to be gapped. ... Should you decide to re-gap your Iridium Power plug, use extreme caution as improper gapping may damage or destroy the Iridium center electrode or porcelain center.
