Mazda CX-5 Service & Repair Manual: Spark Plug [Skyactiv G 2.0]
Purpose, Function
-
The spark plug generates spark, ignition of the air-fuel mixture occurs, and combustion of the air-fuel mixture is triggered.
Construction
-
The spark plug is installed to the cylinder head.
-
Iridium on the center electrode and platinum on the ground electrode are used (iridium spark plug).
