Review on NGK (4469) LFR5AIX-11 Iridium IX Spark Plug (8 Pack): Superior Performance and Enhanced Durability for Optimal Engine Ignition by Alan Pfeiffer

Revainrating 1 out of 5

Good replacement for the original candles.

Replaced original plugs with these and all is good. The gap was set at 0.36, but the book calls for 0.43. Managed to open the breach safely. I know you shouldn't hook up Iridiums, but the truck works great with spark plugs.

Pros
  • Easy to read control panel
Cons
  • No
