Champion fine wire spark plug gap

When replacing spark plugs, ensuring that the plugs have the proper gap is critical to engine performance. 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. Not always. In the past, it was necessary to gap spark plugs, but today spark plugs are usually pre-gapped.

It is advisable to double check that the gap is correctly set to the vehicle's recommended setting when installing spark plugs.

The gap setting is different for each vehicle but most are somewhere between 0. Clean the spark plug. If it is new, this shouldn't be an issue; however, if you are checking a spark plug that is currently in the vehicle, it might be dirty on the contact points.

Never use abrasive materials to clean a spark plug. Measure the existing gap of the spark plug. Using your gap gauge or feeler gauge, run the tool through the electrodes to determine the measurement.

Take note of the measurement and compare it to the recommended setting listed in the owner's manual. Make any needed adjustments. Select the correct measurement on your gap gauge or feeler gauge.

If the tool runs through the gap without touching the electrodes, the gap is too big and must be narrowed. 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. If you snap off the bottom electrode or damage the center electrode from excessively prying on it, you'll need a new spark plug.

Precious metal iridium or platinum center electrodes can be very delicate when it comes to prying them. It is important to use the proper spark plug gapping tool.A spark plugs gap directly affects the tip temperature and the voltage necessary to fire the plug. Champion 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. Even if the preset gap matches that required by your engine, it is always good practice to physically check the gap as it may have shifted during transportation not all spark plugs are packaged in a way that protects the firing end.

Plug manufacturers typically warn against gapping fine wire spark plugs due to the fragile nature of their electrodes. However, Champion understands a spark plug can only operate to its optimum potential if properly gapped.

Proper gapping technique should be followed with any spark plug, but special care should be taken with fine wire plugs. Modified Vehicles. Proper gapping is especially essential in modified vehicles. The ignition process is affected by increased compression, fuel type, nitrous and high output ignition systems. To contact them, click here.

Read on to learn about the different types of gap tools available and check out this article to learn how to gap a spark plug. Assures optimal spark plug performance Using a spark plug gap tool allows you to achieve the exact measurement recommended by the manufacturer. This boosts the efficiency of the spark plug by ensuring its putting out the correct spark to ignite the air and fuel mixture to power your vehicle. You may need to adjust the spark plug gap to ensure the vehicle performs as the manufacturer intended.

Performance applications From stock car and other racing applications to simply wanting more control over the settings of your spark plugs, checking the spark plug gap allows you to achieve your performance goals. Help prevent premature plug failure Having the proper spark plug gap can help reduce the chance of burned electrodes that can lead to premature spark plug failure. Featuring several metal blades or wires in different thicknesses, a feeler gauge looks like a pocket knife.

Each blade or wire is a specific thickness marked in thousandths of an inch imperial or millimeters metric. Ideal for use with iridium spark plugs and other plugs containing precious metals, feeler gauges are more accurate than other types. Named for its coin-like shape, a coin style spark plug gauge features measurements around the edge.

This type of gauge is also called a ramp style gauge. Economical, you can bend the spark plug electrode with this tool but accuracy can be an issue due to the gradual slope of the edge.

Using a coin gauge can damage the precious metals in this type of spark plug. The wire loop style is also shaped like a coin but it has several wire loops of different thicknesses protruding from the edge. As accurate as a feeler gauge, it has a hook to bend the spark plug electrode.

A drawback is the limited number of loops, which can make it ineffective for odd gap sizes. Learn more about quality spark plugsfind your partor find where to buy your part today.

One of the most contentious areas of disagreements surrounds fine-wire spark plugs. It seems that everyone has an opinion about platinum and iridium plugs compared to the standard copper-core version. This compares an extended-nose plug left to a standard-reach plug right. For street engines, the extended-nose is good for part-throttle efficiency.

The short- reach is far better for high output engines where the longer ground strap could get hot enough to cause pre-ignition. The Basics. Pre-ignition is where combustion initiates before the spark plug fires as the result of an extremely hot, glowing ignition source in the chamber. Many times this is traced but not limited to a long ground strap used on an extended-nose spark plug.

This keeps the ground electrode short, minimizing its path to the cylinder head where the heat can be dissipated. Fine-wire plugs like this Denso Iridium left requires much less voltage to fire the same spark plug gap versus a standard copper-core plug right. This Denso plug is called a U-Groove referencing the U-shaped ground strap.

Copper is used as the core material for nearly all spark plugs. This applies to fine-wire plugs as well, which use a copper core to improve conductivity. The heat range is established by the distance the heat in the center electrode and insulator ceramic must travel before it contacts the steel body of the spark plug.

From there, the heat is dissipated into the cylinder head and eventually into the cooling system. Cold spark plugs offer a shorter heat path to the shell. Most competition engine builders commonly choose a colder heat range plug to prevent possible engine damage.

The addition of precious metal in the center electrode has nothing to do with the heat range of a spark plug. The heat range is designed into the relationship of the ceramic to the plug body. The plug on the left is a cold plug with a shallow ceramic depth. The plug on the right is a much hotter plug with the ceramic connecting with the outer shell much deeper.
