However, a common range for many 1993 Silverado engines is 0.040 to 0.050 inches (1.02 to 1.27 mm).
To find the exact specification:
1. Locate your owner's manual: This will list the correct gap for your specific engine. The engine size (e.g., 4.3L, 5.0L, 5.7L, etc.) will be clearly stated on a sticker under the hood or in the doorjamb.
2. Check the spark plug packaging: If you're replacing the plugs, the packaging may specify the correct gap. However, it's still best to verify with the owner's manual.
3. Consult a repair manual: A repair manual specific to your year and engine will provide detailed specifications.
Do not rely solely on this general range. Using an incorrect gap can lead to misfires, poor performance, and engine damage. Always consult your owner's manual or a reliable repair resource for the precise specification for your truck.
