Question

technician a says that spark plug heat range is how much heat spark plugs can physically handle. technician b says using the wrong heat range plug can result in pre-ignition. who is correct?

a. technician a

b. technician b

c. both technician a and technician b

d. neither technician a nor technician b

Explanation:

• Spark plug heat range refers to the spark plug's ability to dissipate heat (how much heat it can handle). So Technician A's statement is correct.
• Using a wrong heat - range spark plug (either too hot or too cold) can lead to issues like pre - ignition (if the plug is too hot, it can ignite the fuel - air mixture prematurely). So Technician B's statement is also correct.

Answer:

c. Both Technician A and Technician B
