Buying Guide for Best spark plugs
Spark plugs are one of the most important elements when it comes to engine maintenance. However, most drivers or vehicle owners are completely unaware of the importance of these vital parts. Dirty, worn or old spark plugs will prevent your engine from performing to its optimal capacity. Therefore, installing the spark plugs for gas mileage will ensure your engine utilizes less fuel and runs cleaner and smoother. Replacing your spark plugs regularly offers the following benefits.
- New spark plugs ensure you engine performs at the highest efficiency levels and achieves peak performance. Every vehicle will misfire at some point on the road. However, as those issues become more frequent, they might lead to serious issues on your vehicle. For example, they can lead to wasted gas, increased exhaust emissions as well as reduced power. Misfires can also make older vehicles to stall or buck. As you can see, you have enough reasons to ensure your vehicle’s spark plugs are in great condition.
- New spark plugs can also improve cold starting significantly. Dirty or worn spark plugs normally require stronger voltage to start a vehicle. Therefore, if your vehicle’s spark plugs are worn or dirty, you might end up with a dead battery. Therefore, ensuring your vehicle has a good set of spark plugs translates to lesser voltage requirements, which is good for your battery.
- You also need to consider catalytic failure. New or properly functioning spark plugs significantly reduce catalytic converter failure. A single misfire can dump a huge amount of fuel into your vehicle’s exhaust leading to overheating as well as converter damage. As much as your vehicle may run even after these issues, it will consumer a higher amount of fuel than normal situations. You also need to note that replacing your vehicle’s catalytic converter costs much higher as compared to a new set of spark plugs.
Therefore, when it comes to replacing dirty or worn out plugs, it’s advisable to do it as early as possible. Ensure you do it immediately when your mechanic advises you to do so. Doing that early enough helps to minimize further issues on your engine while keeping costs low. Having said that, here are some of the best performance spark plugs you should consider installing on your vehicle.
