Spark Plugs
Don't know about less then 100 shot of nitrous on a slant, but do not run an extended nose spark plug with over 100 NOS. The ground electrod is too long and will not disapate the heat fast enough. It will over heat and act like a glow plug. This has nothing to do with heat range. On my nitrous motors I run either a NGK B7ES or B9ES. The 9 being the colder plug.
