Are these things any good? A set of 8 will cost me $75, does anyone thing they are worth it?

Weren't those the ones that MMFF dynoed for 20 horsepower on a blown motor? Before you put those in I would make sure that you have NO problems with detonation, running lean/rich, etc.

on an NA application? not worth it *AT ALL*. Nothing beats a good old fashioned copper plug on a windsor motor. Autolite 25's, yours for $0.99 /a piece. Gap it right, and change 'em often (I do anyways). heh.

NGK is one of the best plugs on the market. You may not see that much of a gain with a N/A combo but with a power adder you can see as much as 15-20hp. I've used both NGK and Denso plugs. I'm currently running Denso's and find them to foul quicker than the NGK's.
