The recommended spark plug gap for a 2001 Chevrolet Suburban 1500 depends on the engine it has. There were several engine options available that year. You
must check your owner's manual to find the correct specification for your specific engine.
Without knowing the engine (e.g., 4.8L, 5.3L, 5.7L, 6.0L), providing the correct gap is impossible and could lead to engine damage if an incorrect gap is used.
