Spark plugs are a key part of maintaining a petrol power tool, especially STIHL chainsaws, and you may think that one spark plug is much the same as another. A standard NGK spark plug and NGK spark plugs sold by STIHL may have the same part number stamped on them, but the STIHL NGK spark plug has some key differences. Usually near the spark plugs at the store there is a booklet showing your old model of spark plug and what model the brand in front of you is compatible with.
If your chainsaw is not running properly, it could be due to a bad spark plug. If your chainsaw is not running right and the electrodes look fine, try replacing the spark plug first because that’s normally all it takes! Bad spark plugs in chainsaws can be a common problem, and it’s important to know what causes them so you can prevent it from happening.
Spark plugs are cheap! Before installing the new plug, you should check in your user manual and find the proper gap. Preventative maintenance is the key, have your spark plugs inspected every 30,000 miles and replaced when the gap is beyond what is specified by the vehicle manufacturer’. Most spark plugs have a factory service interval of 100,000 miles, though some may be as much as 120,000 miles.

What are the longest lasting spark plugs?
Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency.
What causes spark plugs to go bad quickly?
Overheating. Repeated overheating of the spark plug tip can cause the plug to prematurely fail. Overheating can be caused by many things like pre-ignition and a malfunctioning cooling system. Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail.
Should I change spark plugs after 10 years?

What happens if you don’t replace spark plugs?
Spark plugs will depreciate over time, so various engine issues will arise if they are not replaced. When the spark plugs do not generate the adequate spark, the combustion of the air/fuel mixture becomes incomplete, leading to loss of engine power, and in the worst-case scenario, the engine will not run.
How often should I get a tune up?

How often should ignition coils be changed?
While ignition coils do not have a service interval, they do have a lifespan. There is no specific mileage or age to replace them. They should only be replaced when they are bad. If you notice any cracks on the plastic or epoxy, and of course misfires, then it is time to replace the ignition coils.
Do expensive spark plugs make a difference?
High performance Noble metal plugs can perform consistently and well, which helps to maintain the engineered performance of the engine. They won’t make the engine perform better than it did when it was new, but they will help it stay at that level longer.
Is Bosch spark plugs better than NGK?
NGK spark plugs are more expensive than Bosch’s spark plugs, but their quality is outstanding. They offer excellent performance and perform better in colder weather conditions.
