    Just a normal few bucks plugs is good enough. Comparing the prices we can change a few times more to those $20 plugs.

    Think it's just logical that if you buy a plug too hot for your bike, confirm pop hole in piston one.

    Just "downgraded" to some $9 Denso plug.
    But haven't go webby and see the specs yet.

    heat intensity leads to lean burn out....that applies for extreme case....

    As for Super4...stick to the OEM spark plugs.....and of course stick to the stock heat ratings....
    am i right to say that using any plugs with too high a heat rating will cause that?

    Since we toking abt spark plugs,
    wat I always hear is that Super 4 doesn&#39;t require the use of Denso Iridium or any other expensive plugs...
    not much of a difference...
    anyone care to share?

    those are performance parts, meant for performance vehicles.. might have some effects on R1...etc... but then those are manufacturers claims... unless you are into racing technology, doube we, layman, can even feel any real difference...

    Hi,

    Tried using the cheaper (&#036;3.50 per piece) Denso plugs (U27FER9) on my spec II...
    performance wise still normal, except that the rpm fluctuates alot....

    now using back the normal NGK ones... dun feel much difference in performance though... except slightly more stable rpm..

    Hope it helps...

    personally denso iridium and normal denso got diff on my bike. throttle respond, pick up slightly slower and the when u start ur engine....easy to start without throttle.

    aniwae how to adjust spark plug gap?

    Since we toking abt spark plugs,
    wat I always hear is that Super 4 doesn&#39;t require the use of Denso Iridium or any other expensive plugs...
    not much of a difference...
    anyone care to share?
    if u use Iridium, u got to go to higher RPM to feel the different.
    as some of them say, more for lacing lacing lo..

    S4 use normal plug is good liao..its a low maintainance bike...why make it expensive leh? hehehe..

    Spitefire i heard not good..
    cant comment on the plug coz i neber used before..just HEARD about its comment.

    Hi, anyone out there know the correct spec for spark plug gap for Super4 CB400? I have a VTEC-II.

    I know most people don&#39;t gap their own spark plugs and just install them but surely there must be a recommended gap so that we can check new plugs then later clean, check and adjust plugs. Also where is a good place to buy a gap meter?

    Spark plug gap refers not to the valve, but to the distance between the electrodes on the spark plug itself. For example, I have NGK CR8EH-9&#39;s in front of me. On the box diagram, step 1 tells you to check the gap and shows you exactly what the gap is.

    Every engine (bike, car, whatever) has a spark plug gap specification for it to run optimally. When I tuned my own car when I was studying in the US, one of the things I would do is measure and set the gap before installing each spark plug. It can be done using a very cheap tool that looks like a disc with varying thickness all the way around. Usually the gap specification is in the owner&#39;s manual but I don&#39;t have the manual for my VTEC II.

    Here is a site that shows this for a different bike but concept is the same:
    Honda Ignition Timing Adjustment

    Woah, not alot of ppl here does their own spark plug gap since the plugs which they can get off the shelve works alright.

    But if you really wanna get the tool I believe those hardware shops do sell the thickness gauge
