What Spark Plugs?

[Trapper50cal]

NGK V-Powers are great, but the Nippon Densos I got w/ a tuneup kit have been just fine.

I have used every plug on the planet; the best I have
found are the either the original or Split-Fire(really)

If you have an old worn out electrical ignition system,
and do not plan on replacing everything, I would suggest
IRIDIUM plugs by Denso; they need less energy to
make a good spark, so work well in older systems.
I use them and they are great; only thing they are expensive,
around $10-12 US each, but will outlast the truck.

Hi Grey, based on your recommendation I´m diving-in on the Denso Iridium, for my 1984 FJ62 3F engine (factory original). The thing is that you just can´t trust suppliers here, and using web resources to find ther right model number for sparkplug has been for me difficult.

I´m counting on your wisdom to sort this out; I read before that Platinum is out for my dear “Burra” which is how we lovingly call our Land Cruisers FJ60’s. Thanks

Why is it so hard to find spark plug numbers? A cursory search on google gives you dozens of 3F plug part numbers. Before you put a new plug in , you should always compare the old with the new for the protrusion length.
I doubt Iridium plugs will make much difference on a slow revving old 3F
I used NGK 1028, they were just fine
