Review on πŸ”₯ NGK (3459) ZFR5N V-Power Spark Plug: Boost Performance & Efficiency with 1-Pack by Kyle Lawrence

Revainrating 5 out of 5

Replacement Part for Jeep 4.0

Bought six of these to replace the spark plugs on my dad's 2004 Jeep Grand Cherokee WJ 4.0 inline six. Same part number as the one I pulled (which has never been changed before). I had to adjust the spacing a bit to get it up to factory specs, but no worse than any other time I've changed spark plugs. The price was a bit higher than the local auto parts store but they didn't have these connectors so it was easier to order them yourself along with some other Jeep parts.

Pros
  • Absolutely Amazing!
Cons
  • Not sure
