How often should spark plugs be changed?
Spark plugs are somewhat durable components and don’t need to be replaced too often, that said, the general recommendation is about every 30,000 to 90,000 miles. Each vehicle may differ on when they should be replaced.
What happens if you don’t change your 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 do I know spark plugs need changing?
If it takes longer to accelerate, there’s less power to pass a car, for example, the issue could be worn spark plugs, they need replacing. However, a bad fuel filter, dirty or clogged fuel injectors, as well as issues with the oxygen sensor and ignition system can slow acceleration.

What is better iridium or platinum spark plugs?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
What is the cheapest way to increase horsepower?
More fuel/air equals more horsepower. Cold-air intakes also (as the name implies) draw cooler air from outside the car engine compartment. Cooler air is denser, again resulting in the computer increasing the amount of fuel, helping the engine increase horsepower.
Are premium spark plugs worth it?
If you want long-lasting plugs that will reduce the work you need to do replacing plugs and don’t mind paying extra for that luxury, yes. If you are designing an extremely high performance car where the plugs will be subjected to extreme conditions, they are probably a good idea.
