what spark plug

[Boss_302]

hey guys need to know what spark plug to go with for a kb2.2 at 15lbs of boost.

 

[bigmoose]

i would go with either a ngk BR7EF or a TR7IX. The BR7 is a copper plug and the TR7 is an iridium plug.

ok sweet thanks guys one more quick ? what to gap them at?

 

[cobracide]

.30-.35 gap, depending on boost
When running high boost it has recently been noted that .032 is good for for up to 15psi. boost, and .028 for over 15psi. boost
