Failing that, you can find this information:
* Online: Search "[Your Chevy S10 Year] [Your Engine Size] spark plug gap" (e.g., "1998 Chevy S10 4.3L spark plug gap"). Many automotive forums and websites provide this information.
* Parts Store: A local auto parts store (like AutoZone, Advance Auto Parts, or NAPA) can look up the correct gap based on your vehicle's information.
Attempting to use an incorrect spark plug gap can lead to poor engine performance, misfires, and even engine damage. Always refer to the correct specifications.
