Review on NGK CR7HSA Standard Spark Plug by Terry Herrera

Revainrating 5 out of 5

Fixed scooter starting and misfiring issues.

Replaced defective engine spark plug on a Chinese GY6 scooter. Starting problems are gone, misfires are gone. Very good price and long life of this NGK. After this candle, two Chinese At7c were killed, the electrode insulator of which failed.

Pros
  • Absolute legend
Cons
  • So far so good
