Causes of pre-ignition include but are not limited to a buildup of deposits that can become incandescent in the combustion chamber, improper installation torque being applied to spark plugs, and having spark plugs with a heat range that is too hot for the engine's operating condition.
FAQ - Answer 1	Yes, this interval depends on what type of spark plug your vehicle requires. Refer to your owner's manual or contact your vehicle's manufacturer for more information.
FAQ - Answer 4	Yes. When ACDelco spark plugs are manufactured, they are pre-gapped to the correct gap specification.
