Engine knock or pinging is knocking in spark-ignition internal combustion engines occurs when combustion of the air/fuel mixture in the cylinder does not start off correctly in response to ignition by the spark plug, but one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front …

What does a spark knock sound like?

Spark knock (detonation) is an erratic form of combustion that occurs when multiple flame fronts occur simultaneously inside a combustion chamber. … The multiple flame fronts collide, creating shock waves that produce a sharp metallic pinging or knocking noise.

What does detonation look like on a spark plug?

With the early signs of detonation, the shock-wave will also rattle rings causing the tiny amounts of oil that now gets by rings, to be fused to the white porcelain as tiny black specks, also fused as specks are soot that was clinging to clearance volume surfaces in the relatively “still-air” of the boundary layer.

A dirty air filter is not going to cause engine ping/knock. If anything, IF the air flow were to be reduced, that would cause a rich air to fuel ratio, which is the opposite condition of why an engine would ping/knock.
