Review on πŸ”₯ NGK 4291 V-Power Spark Plug - ZFR6F-11: Boost Engine Performance with a Single Pack by Kenny Outlaw

Revainrating 5 out of 5

You can't go wrong with NGK!

I have tried many different spark plugs and found that NGK copper plugs (nickel plated copper in this case) do not go wrong. Although copper candles don't last as long as platinum or iridium candles, they work better and are much cheaper. In my case I put them on a 5.9 Magnum motor to replace the factory recommended champions and now the motor revs much more freely but the champions are badly worn so this is not a valid comparison.

Pros
  • Spare parts
Cons
  • Minor problems
