Message the ngk part number is ZFR6F-11

same heat range as the pfr6b-11b, and they have an exteded tip electrode, wich puts the spark in the same exact spot as the stock tt plugs. i have a set of twin turbo heads here, and with both stock plugs and copper plugs installed, they both have the eclectrode in the same exact position.

i have been running these with great sucess, and nobody can argue with that. they wont last as long as the platinum ngk's, but they DO make the car run better in my experience, and they are only $1.39 each. copper conducts the spark better than platinum.
