Types Of Spark Plugs
Spark plugs are one of l7t spark plug’s essential elements. L7t spark plugs have four key characteristics. They come with an iridium tip, a factory preset gap, and a thread size of 14 mm with 1.25 pitch. This makes them unique.
Basically, different spark plugs work well for different engine types. For instance, some are made for regular use in standard vehicles. Others are meant to be used in extreme conditions only. This means it is important that one pays attention to what type of spark plug their vehicle requires. This is because using the wrong one can cause engine damage and reduce performance.
Here are the different types of spark plugs:
- Standard spark plugs: These are meant for normal everyday use. These do not have special requirements for usage. This means they work well in standard vehicles. These are the most commonly found in the majority of cars, trucks, and SUVs. These are affordable and provide reliable performance.
- Iridium spark plugs: These are designed for high-performance engines. Iridium is denser than other metals used for spark plugs. It has a higher melting point, which makes it more durable. It will not wear down as fast as other spark plug types. Even after long periods of use. Also, because of its smaller size, it will provide a more focused spark. This leads to better combustion, improved fuel efficiency, and increased power output. All these features make it ideal for high-performance vehicles. For instance, sports cars and luxury vehicles.
- Resistor spark plugs: These help reduce electrical interference. Electrical interference can be harmful to other components in the vehicle. Especially those that rely on wire systems. Thus, these are usually found in vehicles with advanced onboard computers. In simple terms, cars that will be affected by electrical noise. These are often found in vintage cars or classic collectors’ cars. Cars that do not have advanced suppression systems in place.
- Long-reach spark plugs: These are specifically designed for engines with deeper combustion chambers. These combustion chambers require a longer electrode reach for proper ignition. These are often found in heavy-duty vehicles. Like commercial trucks and construction equipment in extreme driving conditions. Long-reach plugs help ensure reliable ignition in challenging environments.
Durability & Material Of Spark Plugs
- Steel: Steel spark plugs have been made using a steel core. While the center is generally made of copper or other conductive materials. The reason other materials are not used as the core is because of steel’s resistance to wear. It is tough and can withstand the harsh conditions that are usually found within an engine. That is why steel plugs are ideal for both regular and heavy-duty use. They do not bend or deform easily even under extreme heat.
- Copper: Copper spark plugs have a core that is constructed using copper material. Also, copper is often combined with other materials to add to the conductivity. Copper spark plugs are valued for their conductivity properties. If the engine requires more power, these plugs will do just that. They ensure better power transfer. Additionally, copper plugs have superior heat dissipation properties. This means they will stay cool even when used for extended periods. Unfortunately, copper plugs wear out relatively quickly. This makes them more suitable for short-term or high-demand applications. Like racing vehicles. They are also affordable and provide excellent performance in the short run.
- Platinum: Platinum spark plugs have electrodes that are constructed using platinum. Sometimes it may be alloyed with iridium or rhodium. These materials are harder than all other materials used for spark plugs. So, the wear rate of platinum spark plugs is much lower than standard plugs. That is why they are generally used in vehicles that require longer service intervals. Also, because it is harder, it provides a consistently sharp electrode. This contributes to a more efficient spark. This leads to better fuel ignition. In turn, this prolongs the life of the spark plug.
- Iridium: Iridium spark plugs are constructed using iridium. Although this is a denser material than platinum, it will have a similar effect. This will make its tip stay sharp for a long time. Iridium plugs will offer a superior spark as well. Especially under extreme conditions. These are more durable than all previous versions. So they are suitable for high-performance vehicles that require reliable ignition.
How To Choose Spark Plugs
When purchasing spark plugs for sale, buyers should consider the following factors:
- The vehicle's requirements: Different cars require different spark plugs. Useful information on what spark plugs to use can often be found in the owner's manual. As the go-to place for people getting car parts is the dealership, it is advisable for buyers to stock spark plugs that would be suitable for popular car brands.
- Material: As discussed above, different spark plugs are made of different materials. Each with its own advantage. Buyers should get spark plugs with materials that will suit their customers' needs.
- Weather conditions: Buyers should also consider the weather conditions in the area their customers are likely to be in. For example, those in areas with extreme temperatures should stock up on iridium and platinum spark plugs. Those in normal weather conditions can stock up on copper and stainless-steel spark plugs.
- Tip design: Spark plugs come in two tip designs. Gapped and non-gapped. Gapped plugs have a better combustion range than their non-gapped counterparts. However, they are also less durable. Non-gapped plugs are usually durable. Buyers should also consider the ideal electrode material.
How To Use And Replace Spark Plugs
The first step in replacing spark plugs is locating the ignition coil. This may require removing some components to access the ignition coil. Once it is visible, the technician will disconnect the coil wire from the spark plug. After this, they will remove the spark plug using a ratchet and socket. To do this neatly, they will first use pliers to grip the electrical wire. Then, while holding the wire in one hand, they will gently pull it straight out to remove any tension. Once there is no tension, they will use a ratchet to turn their spark plug counterclockwise until it loosens.
The technician will then install the new spark plug. However, before going for the new plug, it is advisable to check for any debris that may have been left by the old plug. To avoid cross-threading, the new plug will be screwed in by hand. The technician will then use a torque wrench to tighten the plug to the required amount of torque as indicated by the car manufacturer.
The next step is re-attaching the coil wire. The first step to using a new spark plug is ascertaining that the engine is at the ideal temperature for usage. Sometimes manufacturers recommend using the new spark plugs while the engine is cold. On the flip side, others advise their customers to use them when the engine is hot. Therefore, refer to the manufacturer's manual for the right time to use L7T spark plugs.
Once at the ideal temperature, run the engine for 15 minutes. This will allow it to warm up. Once it has warmed up, increase the engine speed gradually. This is done over 2-3 minutes until it reaches the desired level. Do this slowly, as sudden increases can damage the engine.
After the engine has heated up and is running well, one needs to make small adjustments to the gap. Rebending the ground electrode so it is close to the center electrode is a small adjustment. The gap size should be the distance between the two electrodes. Use a spark plug gap tool to check the distance. Finally, take a feeler gauge and push it between the two electrodes gently. The feeler gauge will adjust the sparking distance to the preferred size.
