Review on NGK CR9E Standard Spark Plug by Robert Rajagopalan

Revainrating 1 out of 5

Useless Spark Plug for Automotive Engines

After I put it to the test, I found that this spark plug was a huge waste of money... It didn't improve the engine's performance and, in fact, it caused MISFIRES and reduced fuel efficiency. i had to replace it with a better quality spark plug which solved all the issues..

Pros
  • None
Cons
  • Reduced fuel efficiency and caused misfires.
