Anyone tried those new E3 spark plugs? They claim some pretty big things like power and economy (like that any different from any others'). So I just wanted to see if anyone has tried them.
 
whats an e3 plug. i found that any of these fancy plugs do more harm than good with the 4.0

best results ive got was when i used just regular copper top plugs on my 89.
