    These fit my machine and run smoothly, October 6, 2012

    This review is from: NGK (6216) CR9EHIX-9 Iridium IX Spark Plug, Pack of 1 (Automotive)
    These fit my 2007 Honda CB900F 919 Hornet. Went `round and `round on these plugs with the NGK rep, who was helpful. I originally wanted the silver plugs from Accel, like I use in my car, but they don’t seem to have them for the bike and I finished up with the NGK (6216) CR9EHIX-9 Iridium IX Spark Plugs after lengthy discussions with the rep about Iridium. The “9s” are for racing, which I don’t do, but he suggested that they would be excellent for smooth acceleration, like getting on the expressway.

    Probably the largest issue was the torque. NGK recommends a torque of 7.2 to 8.7 ft lbs, but when you get the plugs it says 1/2 a turn on the box, which turns out to be a lot more than 8 ft lbs. The manual I have says tighten a 1/2, back them out, and then retighten an 1/8 turn. Well, 1/2 a turn seems a lot tighter than they should be so what I finished up doing was to tighten the plugs about a 1/4 turn or so, hard, but not tight, and then backed them out (like the manual says) and set them at 8 ft lbs, plus a nudge, because 8 ft lbs just seems a small loose to the feel, although the plugs I took out (not sure if they were factory installed or by someone else) felt a smidge (all technical stipulations!) beyond finger tight.

    In the ancient days we used to sterile and reuse plugs and just replace the crush rings, because they had to be “seated” correctly. We didn’t tighten them, loosen them, and then torque them, maybe things have changed.

    I didn’t have the factory plug socket, so I bought a regular deep well and used a swivel and an extension to get the plugs out. I loosened the tank end bolts and slid the tank back and raised it up. Later, I read that you’re supposed to go in from the warmer side. Oh, well.

    I couldn’t find a 16 mm socket with the rubber inside, but I used a tool that’s like a cut of rubber hose on a handle that the plug fits into and holds it while you get the threads started. I guess a 5/8 spark plug socket with the rubber inside would have worked.

    I did gap the plugs, but I believe the next time I will leave them because I don’t reckon widening the gap to the recommended gap noticeably increases the combustion effect for my use, and the plugs I received were within the factory gap array.

    It seemed like the plug wires could only go one way, but next time I will tag them and take a photo so I don’t waste time “making sure” I have them on the right plugs. Like it wouldn’t run, right?

    Excellent luck!

    NGK is a fantastic brand and I use their spark plugs in all my vehicles. I recently replaced my spark plugs in my 2001 Honda VFR 800FI. This is a excellent solid substitution plug. I am wondering about the longevity but I know the Iridium plugs in my car will last at least 40k. My manual states to replace the plugs after every 12k but the originals were ordinary Denso plugs. These are much surpass.

    Bought these for my 5th gen 1999 Honda VFR 800. Came gapped perfectly for the bike from the factory. Don’t know what else to say about these. They’re NGK Iridium plugs so you know they’ll last for the full substitution interval in your manual.
