Champion F-14-Y replacement

Post by 61 Waycrosscomet »

So in googling replacement for the 144 spark plugs it comes up with about 23 different makes.
I'm sure some are better for this car than others and wondered what works best as a replacement.
As always, Thanks in advance.

I believe NGK is the only U.S. plug manufacturer, these days. I've never ran them in my engines, don't know quality.
All of the old major brands are made elsewhere. YMMV

My personal opinion is that I would not use Champion plugs in my lawn equipment.
NGK or Bosch are far superior. I have no experience with Denso so I cannot comment on them. E3 and the other “designer” brands of plugs are hype and have no proven advantage.
I use NGK platinum in my Cyclone.
