    I have heard alot of different things, but was wondering if anyone knew the best spark plug to run in the 2f engine, alot have said to run NGK, but others say champion plugs run better, going to be replacing them, and was wondering what others thought?

    ND plugs are OEM, I have had the best luck with them, and prefer them.
    (If they made them for my John Deere 'B', I would have them in there, instead of chumpions)

    Good luck!

    How can you tell if the plugs are too hot, or not hot enough? Would they have any affect on random pinging?

    ND is my plug of choice, but NGK are also recomended for cruisers in the FSM.

    Bosch plugs are trouble in Asian (not Aisin) motors... that's always been my experience. So much trouble that I won't use them in anything. Well, unless i happen onto a bimmer!

    I agree with that, years ago I replaced the cap, rotor, plugs and wires with Bosch on a 22re.......it ran like crap, swtiched back to OEM and it ran great.

    Yea, I also agree about using OEM ignition parts. As for plugs, I use NGK BPR4EY v-power. The '4' indicates indicates a pretty hot plug, though, I believe to keep them cleaner due to the loose tolerances of the 2F. Same with the ND W14EXR-U. Makes you wonder how important it is to keep a cooling system in optimal condition in order to run such a hot plug. Any weakness in a 2F's cooling, quickly shoots the temps up. This brings up another topic ...running cooler plugs (higher number) for hotter running conditions or for overgapped plugs with aftermarket ignitions.

    Picked up the plugs at a local Toyota Dealership for right at $2 (they offer a discount to landcruiser owners, gotta love that), which made me go ahead and pick up a cap and rotor. But i am going to be installing all that tomorrow and will post a reply on what difference i noticed, thanks again for the help.

    Would like to add, just finished installing new OEM ND plugs, rotor and cap and would like to say that, the ole' cruiser is running better than ever, the previous owner had installed NGK plugs but the ND plugs seem to make the 2F run alot better, looks like the 62 is gonna be getting some more plugs next week.

    The temperature of a plug is greatly affected by the length of the cone that the electrode is in. The longer the cone the more heat that can build up as it the heat is dissipated through the insulator and to the block, the shorter it is the quicker the heat is dissipated thus a cooler running plug. A hot running plug may cause pre-ignition/pinging. (At least this is what I have been told)
    Anyone ever index their plugs on a 2f?

    Jwest, I run the exact same plug and heat range as you do.. I am being lazy and am trying to overcome a weber carb that is still running rich after a bunch of re-jettings since I moved to 7500 feet.. I also run them slightly overgapped w/ a petronix igbition module and a hot coil.. I like the hotter plugs.. they dont seem to foul as quickly on my 1 mile commute to work (it never warms up!).
