With modified engines (those engines that have increased their compression) more heat is a by-product of the added power that normally comes with increased compression. In short, select one heat range colder for every 75-100 hp you add, or when you significantly raise compression. Also remember to retard the timing a little and to increase fuel enrichment and octane. These tips are critical when adding forced induction (turbos, superchargers or nitrous kits), and failure to address ALL of these areas will virtually guarantee engine damage.
BKR8EIX is two steps "colder" than BKR6EIX and Gap is .03" (0.8mm)
If your vehicle requires 6 heat range, these will be two steps colder.

For modified engines, please do your research before you purchase any plug.
