The spark plug gap size recommended for a 2008 Honda Fit is .044 inches. Spark plugs play a crucial role in igniting the air/fuel mixture, which results in the combustion process that powers your engine. These small yet essential components generate an electrical arc between two separate leads, allowing electricity to cross the gap between them. While spark plugs can enhance performance in specific scenarios, the improvements in horsepower are usually modest, typically around one to two percent. Even when replacing worn-out plugs with new ones, the performance gains are not likely to be significant, serving mainly to maintain your car's optimal functionality.
