This ignition forces the piston downward, generating power for the engine. The piston is pushed back up again by exhaust, and then the cycle repeats. Like most engine parts, spark plugs can fail for a ...

No, diesel engines do not use spark plugs. Instead of relying on physical ignition of the fuel, they run on a compression-based explosion to combust the diesel fuel. To understand how this works ...

We appreciate the wider heat range and the resistance to carbon buildup and pre-ignition. One potential downside to these spark plugs is that some users have reported that they don’t last as ...
