Yes, spark plugs can contribute to engine knocking, especially when:

Wrong heat range plugs are used

Fuel is low-octane o r adulterated

Spark timing is affected due to fouled plugs

This is more noticeable on CNG setups o r during high load hill climbs, AC on. Worn plugs cause delayed o r incomplete combustion, triggering knock.
