Spark plug gap is where spark plug spark discharge is designed to take place. Spark Plug Gap - understanding the basics For Champion spark plugs it is a little less logical and is as listed below:

Part numbering for Brisk, NGK and Denso spark plugs is reasonably logical with the trailing digits transposing directly into size in mm. Brisk RR15IRY-7, gap size is 0.7 mm, Brisk GOR15YTE-3, gap size is 1.3mm NGK BKR6E-11, gap size is 1.1mm, Denso T16EPR-U15, gap size is 1.5mm, Champion RC10YC4, gap size is 1.0mm).
#BSA SPORTSMAN HV PARTS BREAKDOWN CODE#
If there are trailing numbers after the part number, then the gap should be specifically set as per the manufacturer's part code designation (e.g. 032"., Brisk Extra Turbo Spark Plugs and some others. The " -T" indicate LGS style spark plug with a Tighter gap than standard LGS style spark plug and should be used on applications where the recommended gap setting is less than. The exception are for example spark plug part numbers with gap that does not need to be adjusted and can not be changed, such as Brisk Premium Multi-spark plugs, Brisk Premium LGS Spark Plugs, Brisk Premium LGS-T spark plugs, Brisk Extra Turbo Spark Plugs and some others. If your spark plug part number has no trailing digits then (for most part numbers) it will be preset to this specification. Most Brisk and other manufacturer sparkplugs are preset to around 0.75mm - 0.8mm. Also, the spark plug gap should never exceed. Excessive changing of the spark plug gap setting will result in weakening of the spark plug ground electrode and can lead to breakage. The spark plug gap adjustment should not be changed more than 3 times and should not exceed. The force should be applied ONLY on the spark plug ground electrode strap moving it closer or further away from the spark plug center electrode. The very most important rule when checking or adjusting spark plug gap is, to never pry, apply or exert any force on the spark plug center electrode, or center electrode ceramic insulator.
