Is it bad to change spark plugs after 100, 000 miles?

100,000 mile spark plug changes = another bad idea from auto engineers. Yeah, you save the cost of one spark plug change (vs. a 50k interval) but risk ruining your cylinder heads when you try to pull the original plugs at 100K+ miles. I recently changed my Odyssey spark plugs after 100,000 miles and they were still in great shape.

When is the best time to remove spark plugs?

Penetrating oil applied a day or two in advance will help with potential success in removing the spark plugs. Also, you do not want to try to loosen them when then engine is hot unless you are a member of the extra-work-is-fun club. That is a surefire way to bring the threads out of the head with the spark plugs.

Can a lack of Spark cause an engine to stall?

Just like the lack of spark in the spark plugs can cause an engine to stall, it can also prevent it from starting again. This is especially common when there is oil leaking onto the tip of the plugs.

Can a spark plug seize in a V-8?

Aside from certain Ford V-8 engines, spark plug seizing and head damage is a statistical improbability that you shouldn’t even consider. Many Fords come equipped with 100K mile platinum plugs. Changing them is seldom a problem…Today, most spark-plugs use a tapered seat which forms a perfect seal.

How often do spark plugs need to be replaced?

Check the owner’s manual for the replacement interval. Some automakers require a change at 18,000 miles, some 30,000 to 35,000 miles and others 100,000. 2. Spark Plug Wires

Where does the Spark Go in a spark plug?

A literal spark jumps from the ground electrode to the center electrode on the tip of the spark plug. As this occurs over thousands of times per minute over the life of the electrode, the electrodes wear and the spark becomes less efficient.

How do I know if my spark plugs need replacing?

If the engine is making a pinging, rattling or knock-like noise, or if there is a strong vibration, the spark plugs and/or the spark plug wires could be to blame. 6. Engine Misfires Replace the plugs more frequently if there’s oil on the plug’s tip when removed from the engine.

Are there still spark plugs in newer cars?

Some later models have an ignition system without a distributor, but they still have traditional spark plug wires. Depending on automaker, those harnesses started to disappear in the late 1990s/early 2000s. Newer vehicles have a coil-on-plug ignition system that eliminates electrical problems caused by worn-out spark plug wires.
