The spark plug gap for a 1994 Jeep Grand Cherokee varies slightly depending on the engine. You must check your owner's manual for the precise specification for your specific engine (4.0L inline-6 or 5.2L V8).
The gap is typically between 0.035 inches and 0.045 inches (0.89 mm and 1.14 mm), but again, consult your owner's manual for the exact recommended gap. Using the incorrect gap can lead to poor performance, misfires, and engine damage.
