I can't believe I'm going to open this can of worms but....
Tomorrow since I'm not going up to the Rubicon I thought I'd do some work on the D1 and install the new plug leads, injectors, and ECU. While I'm in there it only make sense to go ahead and do the spark plugs.
The question is do any of you happen to know the plug # for a D2 4.6? The easy answer would be to pull one of mine out and check it, but I'm hoping to pick the plugs up while I'm out today instead of having to make an extra trip into town tomorrow after I've started the project.
I think the OEM number is a champion RN11YCC; standard copper plug. The OEM 'upgrade' should be a Champion platinum RC11PYPB4
I don't really have a special love/hate with most one brand of plugs over another. In my Alfas I always ran NGK - they hated Bosch (I used to refer to the Bosch platinum as the 'self fouling plug'). On my Dodge, ran for crap on Champion but great on Bosch. I haven't had to do plugs on the LR3 yet and it probably needs some bizzaro plug anyway.
Anyway, thought I'd check here briefly to see what I could learn before I start the project.
Next up: what flavor of oil do you prefer and what tires.
