How To Know When To Replace Spark Plugs?
Spark plugs are essential to your engine, so keeping them in good condition is important. You’ll need to replace your spark plugs every 40,000-80,000 miles. It is better to check it in your owner’s manual.
If you notice any of the following symptoms, it’s time to replace your spark plugs:
- Reduced fuel economy
- Decreased performance
- Engine misfires
- Rough idle
These are just a few of the signs that your spark plugs may need to be replaced. If you notice any of these symptoms, it’s best to take your Mazda CX-5 to a mechanic and have them check the condition of your spark plugs.
Spark Plugs Type
When shopping for spark plugs, you’ll need to choose the right type for your Mazda CX-5. Mazda CX-5 uses iridium spark plugs. It doesn’t mean you can’t use platinum or copper, but in general, it does not make sense.
Iridium spark plugs are more expensive than platinum spark plugs, but they last longer. Iridium spark plugs can last up to 100,000 miles before they need to be replaced. Platinum spark plugs, on the other hand, only last 40,000-60,000 miles.
If you’re looking for the best performance and efficiency from your Mazda CX-5, we recommend choosing iridium spark plugs. However, if you’re on a budget, platinum spark plugs will still provide good performance and fuel economy.
