Conditions inside an engine are predictably brutal. As much as modern engines are engineered and built to reduce friction among moving parts, friction – and the heat that goes hand-in-hand with friction – is unavoidable as cylinders get pumping. Depending on engine speed, spark plugs fire 1000 times or more every minute. Wear and tear is a real issue.
No matter how efficient an engine is, a tiny bit of material is left after each combustion. These deposits build up on the spark plugs over time, resulting in uneven performance and even lower gas mileage. In addition, the gap that a spark has to travel to ignite the fuel/air mixture gets larger and larger as the spark plug ages thanks to heat, particulates and normal wear and tear.
That’s why it’s important to have your spark plugs checked (and replaced) according to the manufacturer’s maintenance schedule. Superior materials may have extended the average spark plug’s life, but they won’t last forever.

How much does it cost to replace Mazda CX-5 spark plugs?
The spark plugs on your Mazda CX-5 ignite the air and fuel mixture inside the engine, which provides the drive for your vehicle.
Without them, the engine wouldn’t run and you wouldn’t be able to go anywhere! So it is important to have them replaced at the recommended intervals to keep your Mazda CX-5 running as smooth as possible.
The average cost to have your spark plugs replaced starts at around $100 up to $300+, depending on the type of spark plugs needed.
Spark plugs come in all different shapes and sizes and have a variety of electrode designs and tip compositions. The correct spark plug for a Mazda CX-5 is determined by which plug delivers the best fuel efficiency, transference of heat and final drive.
The cost to replace spark plugs can vary greatly depending on the Mazda CX-5 and if other components, such as the inlet manifold, needs to be removed to allow access to the spark plugs.
