Review on NGK CR9EHIX 9 Iridium Spark Plug by Terry Owens

Revainrating 3 out of 5

Overpromised, Underdelivered Spark Plug

As a result of my tests i determined that this spark plug did not improve the PERFORMANCE of my automotive ignition.The promised increased fuel efficiency was nowhere to be seen..

Pros
  • Easy to install.
Cons
  • Did not deliver on promised fuel efficiency improvement.
