Insert 4 new plugs bingo. I am back in the game - 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 desertcart and got these plugs with desertcart prime. 1. The desertcart price is unbeatable. Dealer prices were 50% more than desertcart. 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.

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! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/6617732-6777-imr9c-9h-laser-iridium-spark-plug-pack-of-1](https://www.desertcart.vn/products/6617732-6777-imr9c-9h-laser-iridium-spark-plug-pack-of-1) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-06*
