NGK Iridium spark plugs
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:
Little known fact: 2005 and later Harley-Davidson EFI systems incorporate an "Anti-knock" feature that operates by reading the current resistance through the spark plugs. The use of any other spark plug other than 'Stock' (6R12) disables the anti-knock feature. (Yes, that means the Gold, Platinum and SE plugs will also disable this function) Here is the website I got that info from: If anyone with EFI knowledge like Fuel Moto knows anything to the contrary, please chime in? |
