Review on NGK IMR9C 9HES Laser Iridium Spark by Gabe Smith

Revainrating 5 out of 5

Correct connector for CBR600F4i 2005-2006

Honda updated the spark plugs in 2005 and recommends them for 600 F4i, 600 RR and 1000 RR engines. Replacing the Honda OEM IMR9A-9H (Honda Genuine Parts) spark plugs that came on my 2006 car with the correct spark plug makes a noticeable difference in performance below 4000 rpm where it was so often absent before. The OEM Honda spark plugs that we originally bought for our 2006 engine were designed for the 2001 F4i and caused a lot of vibration and harshness at part throttle.

Pros
  • Impressive
Cons
  • The list goes on.
