Spark gap for chevy 8.1L 2003

Frank, look under your hood for a "catalyst" sticker. It should have your spark plug gap listed on that sticker along with the size of your motor, etc. Some of the newer vehicles aren't listing it there anymore, but it should also be listed in your owners manual in your glove box - if you still have it. Check the alphabetic index in the back for spark plug gap and if it's not there, check specifications.
