Never apply lubricant or anti-seize on the thread of a spark plug. Doing so can affect the torque applied during installation, leading to potential over-tightening or under-tightening, which can damage the engine or cause the spark plug to break. Spark plugs are typically coated by the manufacturer to prevent seizing and corrosion, so additional lubricant or anti-seize is unnecessary and counterproductive.
FAQs & Answers
- What happens if I put lubricant on a spark plug? Applying lubricant can affect torque, leading to potential engine damage or spark plug breakage.
