what spark plugs to use?
i've got ls/vtec in my car and i'm trying to find out which new spark plugs to order...i know i prolly shouldn't use the craptastic ones that they use stock on a gsr...so here's the run down
b18a1 block
bored out to 82mm
12:1 compression
gsr head stock valvetrain
plus a lot more, but i think that's the essentials for which plugs i need to know...
i don't understand about how or why to go hotter or colder or whatever with plugs, so if u could explain why some are better than others, i would greatly appreciate it...thanks in advance guys

Proper heat range is important so you don't detonate (ping). Use a hot plug on a n2o or turbo, you might just turn that plug into a glow plug and gases will burn when you don't want them to. you want the plug to get to a certain temp and stay there keeping the electrode clean and preventing ping. at least two steps colder when turbo or n2o. higher the # colder the plug. also go colder when raising compression.

now that makes sense..
so can anyone tell me for 12:1 compression if the above mentioned plugs are correct for me, or what people with similar setups are running in theirs and how they work for them?
