Eventually, at around 30,000 miles to as high as 40,000 miles, conventional spark plugs will wear out, which could cause stalling, starting problems and engine misfires. Higher-cost platinum-tipped spark plugs may not need to be replaced as often.
Replacing the spark plugs on your Audi A4 is recommended routine maintenance. Audi recommends replacing the spark plugs on A4 models every 40,000 miles or five years.
The deposits that build upon the plugs can eventually cause them to misfire. When this happens, the unburned fuel in the cylinders can start to eat away at the cylinder walls. This can cause dangerous pressure levels to build up, and it can even lead to engine failure.
A spark plug usually lasts about 30,000 miles, but cleaning them and maintaining them periodically lets your engine perform better and increases your plugs` lifespan. If you see rust, carbon, gunk, dust, or any type of buildup during the inspection, it may be time to clean them.
Most manufacturers recommend replacing spark plugs every 50,000 kilometres, but spark plug quality varies. Some last around 130,000 kilometres, while cheap plugs made of copper may last approximately 40,000 kilometres. “Extended life” spark plugs made of more resilient metals can last up to 160,000 kilometres.
Generally, it`s recommended that you have all the spark plugs (one for every engine cylinder) replaced at the same time. Otherwise, your vehicle might give you inconsistent performance.
Luckily, spark plugs don`t require replacement very often and can go years and many miles before replacement is needed. Most auto manufacturers suggest having new spark plugs installed about every 100,000 miles; however, spark plug longevity depends on the engine, condition, and spark plug type.
Luckily, spark plugs don`t wear out very quickly. You can typically get 80,000 miles on them before they need replacing.
Even if you`re not having problems you`ll still want to have your spark plugs changed out at every 30,000 mile interval. For most drivers, that will mean that you`re due for spark plug service once every 2-3 years!
FACT #4: YOU SHOULD CHANGE SPARK PLUGS EVERY 100K MILES OR SO. So, if good spark plugs are the key to avoiding these issues, how long do spark plugs last, exactly? The general rule of thumb about how often to change spark plugs is that they should be replaced after about 100,000 miles of driving.
It`s a crucial job that spark plugs have because if they`re worn out they won`t emit a spark and start your engine or can even cause significant damage. It`s not just a bad battery that could be keeping your vehicle from turning over — it could be the spark plugs.
Just as your car`s engine needs clean oil to run smoothly, it also needs clean spark plugs. A dirty spark plug can cause problems for your engine, including decreased performance, increased emissions, and reduced fuel economy. That`s why it`s essential to clean your car`s spark plugs regularly.
Spark plugs are designed for long-term durability, meaning that they only need to be replaced between every 80,000 and 100,000 miles. However, they can become damaged earlier than expected and require replacements to avoid pricey engine repairs.
NGK gives them a life expectancy of 40-50k miles. But they have to temper their projections as driving conditions and motor modifications differ. Typically we have found you can expect 60,000 to 80,000 miles on an unaltered motor. NGK Laser Iridium Spark Plugs have iridium center and a platinum ground electrodes.
Causes of a carbon-fouled spark plug include a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture, dirty fuel injectors or idling your vehicle for too long.

100,000 to 150,000 Miles They`re typically made from a high-purity platinum-iridium alloy for impressive heat tolerance and fouling resistance: the number-one plugs killer. You can expect these kinds of plugs to last a good 100,000 to 150,000 miles of usage.
The most expensive type of spark plug is the iridium type. It is harder and more durable and generally lasts longer than platinum types. They have a smaller center electrode and fine wire centers which can generate current faster. It provides better power and complete combustion that leads to better engine performance.
