Review on NGK XR5IX Iridium Spark Plug by Lloyd Edwards

Revainrating 5 out of 5

Didn't fit, can't return, repair

Great spark plugs but they don't fit my 1973 6.6 and I can't return them in a week. My project is behind me so now I have to eat this! I made a call and Revane admitted these plugs were listed incorrectly. Back immediately. Thank you Rewin!

Pros
  • Trivalent coating eliminates the need for anti-seize
Cons
  • Speed
