Spark Plugs in Plano, TX


How do spark plugs work?

Spark plugs supply the spark required to ignite the air and fuel mixture that enters your engine, creating the explosion that produces power in your engine. These plugs are small but are incredibly important and powerful. They create electricity between two leads which aren't touching, but close enough that electricity can jump between them. Spark plugs are part of your vehicle's ignition system, and are responsible for putting the engine's pistons in motion so your vehicle can run smoothly. If you are experiencing issues with your spark plugs and are in or nearby Plano or Richardson, you can bring your vehicle to Sav-Mor Automotive to get them checked out.

How often should I replace my vehicle's spark plugs?

Whether you drive a Ford, Chevrolet, Toyota, Honda, or anything else, the rule of thumb for replacing your car's spark plugs is relatively similar. Usually, spark plugs are very durable and will not require replacing until several years and/or several thousand miles driven in your vehicle. We recommend having new spark plugs installed every 30,000 miles, but this depends on the quality and type of spark plug used. For example, copper spark plugs have the shortest lifespan and spark plugs made of stronger materials have a longer lifespan. 

What happens to a spark plug over time?

Although it takes time for spark plugs to face damage, all spark plugs will invariably wear out over time. When this happens, deposits form on the spark plugs from the air-fuel mixture that constantly enters your vehicle's ignition system as you drive. A build-up of deposits can result in pre-ignition of the fuel, which causes an unreliable and jerky supply of energy to your vehicle. The distance between the two leads also widens over time as a result of extreme temperatures, normal wear and tear and debris. If the gap is too far apart, the spark plugs won't function properly and there won't be as much energy produced for your vehicle to move. Other fixes, such as tune ups, scheduled maintenance, and engine repair, may also be needed if you haven't gotten your vehicle serviced in a while.
