• A. Purple
• B. Red
• C. Yellow
• D. Green

Answer: (B)

A spark plug that has a red color typically indicates that it requires immediate attention. This is a crucial visual cue for technicians because a red indication often signifies that the spark plug is experiencing significant issues. These issues could stem from problems such as excessive wear, overheating, or improper combustion. Addressing this immediately is essential to avoid further damage to the engine, as a malfunctioning spark plug can lead to poor engine performance, reduced fuel efficiency, or even complete engine failure if left unaddressed. Understanding the significance of color codes is vital for proper vehicle maintenance. The other colors like purple, yellow, and green usually represent different conditions or levels of wear that do not necessitate immediate action, allowing technicians to prioritize repairs effectively.
