impressed
I have to say I was a little worried, the picture didn't show the other end and I was a lil scared that I was going to get the wrong part. Other than that I'm impressed on how fast I got them and the price! The cheapest I found them so far. I have a 2005 Honda cbr 600 rr and they where the right ones for my bike, runs like a champ! Thanks

Work great on CBR600RR
No gaping required on 07 CBR600RR. Installed no problems, got my bike tuned after with no issues.

Bought 4, 1 wrong part. 3 Worked great.
I ordered 4 and 1 was a wrong part. The 3 that I installed almost completely eliminated the bogging issue I was having.

awesome product
Once installed and the whether was warm enough to road test the bike I took it for a nice ride. I felt an immediate increase in power off the line and the bike felt a lot smoother throughout the gears and at the top end. Definitely worth the money and will buy again.

Correct plug for CBR600F4i 2005-2006
Honda updated their plugs in 2005 and recommend this for the 600 F4i, the 600 RR and 1000 RR motors. Changing from the Honda OEM IMR9A-9H (original honda parts) plugs that were installed on my 2006 to the correct plug make a noticeable difference in performance below 4000 rpm, where it was previously missing every so often. The OEM honda plugs we originally purchased for our 2006 motor were designed for a 2001 F4i and caused a lot of vibration and harshness at partial throttle.
