How often should I replace my spark plugs?

If you want to use a strict rule of thumb for changing spark plugs, rather than changing them based on plug condition, they should be serviced about every 30,000 miles. Note, however, that they may fail sooner or much later.

Check your owner’s manual or manufacturer’s website for your make and model of vehicle. Driving with bad spark plugs can result in poor performance, poor fuel economy, misfires, or your car not even starting.

Why need a spark plug?

Automotive spark plugs provide the spark that ignites the air-fuel mixture and creates the explosion that causes your engine to generate electricity.

These small but simple connectors create an arc of electricity across two wires that don’t touch but are close enough for the electricity to jump the space between them.

Your spark plugs, along with the electronics and timing that power them, are part of what’s called your ignition system.

How to clean my spark Plugs?

First, disconnect the spark plug wire. Next, clean the area around the spark plug to prevent dirt from entering the combustion chamber when you remove the spark plug. After that, remove the spark plug with a spark plug boot.

Clean the spark plug of light deposits with a wire brush and spray-on spark plug cleaner. Inspect the connector for stubborn debris, broken porcelain, or burned electrodes. If any of these conditions exist, replace the spark plug.

What are gapping spark plugs?

Gap plugs ensure that the gap between the two electrodes is even. Otherwise, your sockets won’t fire efficiently. The setting of the gap between the two electrodes is called the spark plug gap.

You need a feeler gauge to properly gap the spark plugs. It’s a good idea to double-check when installing spark plugs that the spark plug gap is set correctly to the vehicle’s recommended setting.

How long do spark plugs last?

Spark plug life varies by manufacturer and vehicle. However, the spark plugs on most vehicles on the market today should last 100,000 miles or more.

To make sure you don’t exceed the spark plug gap, research the spark plug type to see if they are right for your vehicle. Keep in mind that spark plugs tend to have shorter intervals on most performance and luxury models.

How much should spark plugs cost to replace?

In general, you should expect to pay between $50 and $130. Different types of spark plugs vary in their longevity and price.

A pack of 4 copper spark plugs averages between $8 and $12, while a pack of 4 iridium spark plugs costs between $35 and $50. Platinum plugs cost something in the middle.

Why do Triton spark plugs break?

Because the original spark plugs can weld to the cylinder head and break into pieces. And when someone tries to unscrew them, the bottom of the plug gets stuck in the cylinder head. Fishing out the broken section requires special tools and a trained technician.

Final Thought

You now know that spark plugs are crucial methods to ensure effective replacement and completely clean engine starting and fuel efficiency. Replacement candles guarantee a smooth start and meet all the needs of your vehicle.

However, to get the best performance, you need to choose the right spark plug for your car. Luckily, you don’t have to try any harder because we have already summarized the best models on the market.
