Stick with the NGK or Nippon Denso that the manual recommends.
Is there any reason to pick NGK above the Denso? I looked on sparkplug.com and the Denso lists for roughly 1/2 the price of the NGK.Stick with the NGK or Nippon Denso that the manual recommends.
I have a new set of NGK Iridium plugs that I picked up cheap a while back.
Noticed that the tips are really tiny vs. the regular NGKs. Mike, do you happen to know what advantage (if any) to them is. Hotter spark maybe?
Which would result in what? Or maybe they're just a gimmick.
From my experience, NGKs are the most reliable spark plugs for any kind of motor.
