Short Spark Plugs - The cure for those "To close to the header" Blues.
Over the years spark plugs have actually gotten longer, not shorter. This tends to put the plug boot closer to the header which isn't good. So Accel offers spark plugs that are 1/4" shorter than a standard plug.
These retain Accel's patented U-groove design and are so well designed, one plug will cover several heat ranges.
