The proper spark plug for 4hp Briggs & Stratton is a J8 which I use in all my motors.
official site for Briggs and Stratton Spark Plugs is: http://www.briggsandstratton.com/maint_repair/routine_maintenance/choosing_spark_plugs/ The proper spark plug will depend on the type of 6.5 HP motor that you have. Briggs and Stratton made several different ones and the best way to get the proper plug will be to call an authorized Briggs and Stratton repair shop with the mower make and model numbers.
The Briggs & Stratton 5095 spark plug is commonly cross-referenced with the Champion RJ19LM spark plug. This means the RJ19LM can be used as a suitable replacement for the Briggs & Stratton 5095 in compatible engines. Always ensure to check the specific engine requirements for proper fit and performance.
