Are these plugs good? Or do they make people fall into the trap of "they cost more so they should be good." What plugs have u guys had good experiences with? If i don't usually rev that high while driving, would u guys get the plugs or a pop chrager? Thanx

 

Even if plugs were 1000% better you would probably only gain 1-2 hp or less. The big problem with the iridium plus is that they only last half as long as the platinum - 30,000 instead of 60,000 miles.
