i have an evo 8 with hks version II igntion amplifier , evo green turbo hks 272 , and all the supporting mods to probably do 395whp , i need to know what spark plugs to use .
NGK BPR7ES this is what im going to be using or BPR8ES these are copper, my friends all use iridium 7 and 8 and now then went to 9 because there always burning there spark plugs , can anyone recommend spark plugs or tell me if im right

if u want throw in gaps also

 

BPR8ES or BR8ES are best for your setup since they are one step colder. .022 to .024 is the gap I would use with your ignition amplifier.

 

some one told iridium were not that good plus they r delicate to gap
