is anyone running those NGK Iridium spark plugs? i need your feedback, you like you dislike,please comment if you experience those.

 

I been usin em about a year, 2 bikes. I like em. quick starts, no problems.

 

NGKs were the best in my snowmobile years ago, never ran em in a bike, but I am sure they would be fine

 

I've been running Champion RA8HC's in both my bikes for years. Auto Zone, $1.99 each.

 

I've been running the NGK's in my 08 Heritage with no problems, not sure if I gained any performance like some claim. There is a video on youtube where they run a bike 1st normal and then swap the plugs run it again and it gains 1 HP.

I've never noticed a difference between those precious metal ended plugs and regular copper plugs. I tried em all in my mustang and nothing made any difference,so now I just stick to the cheap oem replacements and change them every year or 2. But that's just my experience with my vehicles. Your results may vary

 

no need for the extra bling when the ignition system isn't designed for it. it may actually cause problems down the road with burning out coils..

i get on avg 80k miles out of a standard set of plugs in all my vehicles.

 

I was really interested in these plugs, till I did some internet research and found this:

 

I run the SE for stock compression. Wonder if it would include these... huh...
