(6777) IMR9C-9H Laser Iridium Spark Plug, Pack of 1

I own a 2003 Honda CBR 954RR that just hit 20k miles I bought it at 8,000. It is my daily commuter vehicle, because parking a car is 6.75 and walk 2 blocks in downtown Cleveland and riding a motorcycle is park next to the building and free. So last week when my bike started running REALLY funny. Sounded like an old Honda CB550 not a CBR954RR. I got worried. This happened once before like 6 months ago. I got a really rough idle and running sound and I kept going about a half mile later it cleared up. Well then came last week. I got about a mile from my house.. it started bogging down and sounding like it was running on 2 cylinders not 4. I ran it home this time parked it. I tried changing the gas (bought a siphon and filled it with 93 octane.) Zero difference. I popped up on amazon and got these plugs with Amazon prime. 1. The Amazon price is unbeatable. Dealer prices were 50% more than Amazon. I got the plugs in 2 days too. THE HONDA MANUAL IS WRONG DO NOT MOVE YOUR RADIATOR AND GO THROUGH THE FRONT! Here is how I did it. Removed the lower cowl. Removed the airvents above the coil. Removed the tank propped it up. removed those vent things going into the bottom airbox (not sure if I had to or not) removed the airbox cover (unplug all the electrical stuff and that last throttle cable leave it attached and swing it off the left side of the bike.) Then removed the 6 screws in the little funnel things inside the airbox. Removed them carefully dont let the screws fall into the carbs. Then removed the airbox bottom. I pushed the rubber sheet covering the plugs up out of the way. I used the tool in the tool kit to extract the spark plugs (first unplugging them) I blew compressed air down the hole (there was nothing in there) I unplugged the coil from the wire harness. THen pulled the coils out. I replaced ONE plug at a time using the and reinstalled the coil. I did that until I was done. put everything back. turned the key on.. VIOLA! it worked.. in fact it works better than I thought. I know have a whole MESS of power I never had when I bought the bike originally. I missed a shift BAD today because of it. So. These plugs get a 5 star review. My problem might have been a lose coil or fouled plugs. I dont know. The bike runs like new now and I have a whole slew of power left. if you got any more install questions you can visit my forum at hvyhitter dot com.

Iridium IX spark plugs NGK brand in so highly recommended in all that has to do with spark plugs for motorcycles, has better performance spark cobustion pa the gas in the engine and better with the iridium electrode that helps improve yourself for the spark. recominedo they are of very good quality.

These specific plugs (NGK6777) DO fit the F4i. For some reason, the pic shows them with a different terminal. Mine arrived and were identical to the OEM plugs. It looks like a screw-on thread at the terminal instead of what is shown. Anyway, mine went in, hooked up with no problems, and started just fine!

Good price for the plugs, only downfall was I ordered 4 and they sent me 3 correct and 1 incorrect. Had to return and bought a plug from the store in person.

Great they worked perfect. Shipped and installed. Perfect fit the first time. I have to use up words, but this was good.

Exactly as what described, quality plugs

These spark plugs work great on my 2002 Honda CBR F4i. The engine is firing smoothly and i'm not have any issues with these.

The plugs themselves are great. They are legit NGK and are of the finest quality. I immediately felt a difference in my 2005 F4i after installing these guys in place of my older worn out plugs. I'm docking 2 stars for shipping though. I ordered 4 spark plugs all at the same time on the same order with the same card. 2 of them arrived in one envelope. 1 arrived in another envelope. and 1 arrived in yet another envelope. All four could have easily fit in the same envelope so I see absolutely no reason for them to do it this way. They all shipped out on the same day too. But to make things worse one of the envelopes got delayed in shipping by a week which means that I received 3 plugs, then had to wait a week for the 4th one.
