Regarding spark plugs, who is correct about factory gapping?

Factory gapping of spark plugs refers to the process where spark plug electrodes are adjusted to specific distances as predetermined by the manufacturer to ensure optimal performance in a given engine. The correct information regarding factory gapping emphasizes that spark plugs are typically pre-gapped to the specifications required for the engine they are designed for. However, it is important to note that some scenarios may necessitate rechecking and adjusting the gap based on specific engine requirements or modifications, as the gap may be affected by factors such as wear over time or differences in performance criteria.

Counterman B's position likely reinforces the understanding that while spark plugs often come pre-gapped, it is essential for a technician or counterman to verify this gap when installing new plugs. This ensures that the spark plugs will function correctly and efficiently in the specific application they are being installed in, as an improper gap can lead to poor engine performance, increased emissions, or even engine misfiring. This context makes Counterman B's statement regarding factory gapping more accurate in the scenario presented.
