Does anyone have any experience or even heard of these plugs before? Seen them on flea-bay, they claim that they increase HP by %3 which would give close to 5 ponies, %5 more fuel efficient, %20 more firing power & increases acceleration by a whopping %10- %12!!! They don't come cheap however, 18 bucks per plug + shipping....ouch!!! lol Any input would on these would be appreciated!!
 
A test dummy would be appreciated. Your application has been accepted. Thanks!!
 
plug bullshit

I wrote ask Ralph in whatever the mag is. He called Yamaha, and they laughed at it. That is what I suspected.

One person on this site years ago, said he stopped on the trail, and changed to these plugs, and he could feel the difference. REDICULOSE.
 
Best plug you can get for big boost or NOS, big waist of $$$ on a stock motor.
 
So the consensus is total waste of money for stock Apex's!! Best off sticking with the ck10's I guess!! ;)!
Thanks for the input!!
