You must consult your owner's manual. This is the definitive source for the recommended spark plug gap for your specific vehicle. The manual will list the correct gap based on the engine's specifications and the recommended spark plug type.
Failing that, the Bosch spark plug packaging or the Bosch website (using the plug's part number) will provide the recommended gap.
Attempting to use an incorrect spark gap can lead to misfires, poor engine performance, and damage to the ignition system. Don't guess – find the correct information from a reliable source.
