Gapping Spark Plugs

Side gapping spark plugs has been use in racing for years to increase horsepower by unshrouding the spark thus allowing the flame created to propagate faster resulting in a more complete burning of the fuelair mix. To decrease the spark plug gap you can use the tools mentioned above or you can push the ground electrode against a soft surface such as a wooden table.

What Should My Spark Plug Gap Be Video

However precious metals began being.

Gapping spark plugs. Gap new as well as old spark plugs even if the package says that the new plugs are pre-gapped. Spark plugs require a precise gap to ensure proper ignition of the airfuel mixture and gapping them requires appropriate tools for your vehicles specific plugs. Therefore if your spark plugs need replacing go out and pick up not only the proper plugs but the tools that will make gapping them easier.

This can result in engine hesitation. Large gap higher voltage requirementsmisfire Smaller gap A narrow gap may give too small and weak a spark to effectively ignite the fuel-air mixture. The gap is the distance between the center and side electrodes so arcing occurs at the proper voltage that ignites the fuelair mixture and generates the combustion that makes the engine run.

Adjusting the distance between the two electrodes is called gapping your spark plugs. The gap should be adjusted by only moving the ground electrode. Which brings us to a spark plugs composition.

By doing it yourself you can use a. Since the gap size has a direct effect on the voltage necessary to jump the gap and ionize light the air-fuel mixture careful attention is required. Also known as side-gapping in a racing or extreme high-performance engine this improves the flame kernel efficiency and propagation through the combustion chamber.

Achieving proper gap distance is important for maximizing the power output fuel consumption smoothness and overall. While plugs are pre-gapped from the factory the gap may need to be adjusted for the vehicle that the spark plug is intended for. Gapping a spark plug involves a spark plug gap tool a coin-like metal device thats tapered around its circumference.

If theyre within 002 and you dont have the gapping pliers few people do but theyre inexpensive then I would leave them alone due to the cost of Iridium plugs. What You Need to Know. If adjusting the gap on fine wire or precious metal plugs such as platinum or iridium be very careful not to apply any pressure or prying force to the fine wire center electrode or insulator as they can be damaged.

There are at least four. How to Gap a Spark Plug - YouTube. There are devices such as wire looking gap gauge or feeler category tools for spark plug gapping.

A pair of spark plug gapping pliers is by far the safest way to gap plugs no matter if theyre Iridium Platinum or copper core. In lieu of a better description this gapping process will. For a long time center electrodes were made of copper and plugs were gapped in a specific manner.

What Is Gapping a Spark Plug. Gapping Spark Plugs Gapping refers to adjusting the distance between the curved conducting electrode and the plug tip where the electricity emanates from. If spark plugs are gapped too wide the ignition spark loses some of its strength as it crosses the spark plug gaps.

This is done by bending the electrode itself via a special gap tool. Many manufacturers offer plugs deemed racing plugs that are side gapped but at inflated costs. Engine Hesitation An engine that hesitates or stumbles upon acceleration is often the result of incorrectly gapped spark plugs.

You need a feeler gauge to gap your spark plugs properly. To avoid problems work on only one plug at a. To do this use either a pair of needle nose pliers or a dedicated spark plug gapping tool.

Gap Spark Plugs. Gapping a spark plug is when you adjust the gap between the spark plugs center electrode and ground electrode. To increase the gap gently bend the ground electrode towards the center electrode.

Some even prefer using coin style tools to handle adjustments. Whats being discussed here is not a true side gapped spark plug but a gapping procedure or electrode modification that allows the spark to actually fire off of the very edge or side of the spark plugs ground electrode. Additionally can spark plug gap affect performance.

However considering the design of modern spark plugs these might leave abrasive and inaccurate damages.
