Platinum, iridium, etc are not particularly good 'performance' plugs...just good
for 100,000 miles
The point is a good idea and plays on the corona effect
Key is their thermal rejection management and I like copper cores for that. Harder
to find these days...also love cut-back plugs and make my own. Last time checked
NGK has them as a custom order and IIRC $200/each with a minimum order
It is best to use OEM
Coils at the plugs has a shorter high voltage run over a single coil and those
coils can be fired with solid state semi conductors. Less silicone iron, so higher
raise time for multiple sparks...if the computer is capable (AKA PWM)
Anti-seize can get you into more trouble with tapered seat and as noted over
torque way easy...better leave that to those who know HOW2...sorry for that one
Careful on some FORD engines. They have a very, very long snout and they get
built up deposits to require special procedures...else they might break in half
