Best Spark Plug for 2F engine (1 Viewer)

[777sam]

I purchased some spark plug wires from Matt for my FJ. The boots on the Japan made plug wires require a plug with a tall spark plug insulator. Any recommendations for a set of 2F engine plugs?

Thanks,
Sam

These can be hard to find locally, you can buy them direct from Denso

W14EXRU
for daily driver/trails

OR

W16EXRU
For engines that see a lot of interstate use, one step colder of a plug.

Since you are posting this in the '40 series forum, I assume you have an FJ40 with an F or 2F. "FJ" could mean pretty much any Cruiser with a gasoline engine. Or even one of those 4Runners with the fugly body option package that Toyota made for a few years

Anyway, unless you have really done some work on her, your low compression low rpm, 1930s technology F or 2F power plant will be happy with almost any plug that will fit, so long as it will actually make a spark.

So, would there be a more better spark plug for a mildly modified 2F block with perhaps slightly higher compression that occasionally sees RPMs as high as 3500 (but not often)? Asking for a friend.

With my OEM rebuilt '86 2F, I've run nothing but Toyota plugs, Denso's W14EXR-U.

Being RPM's got mentioned, after reading this @Mark W post < Click Here > I've up my shift points quite a bit.

I'd consider 3500... "not really out of low rpm" still.

For a quality plug that will last, I am a fan of NGK. The only name brand that I tend to pass over is Champion. But to be honest I can not point to any reason why based of personal experience in Cruisers. I *think* that back in the day I was disappointed with their lifespan in in my 429 Super Cobra Jet. But that was like 47 lifetimes ago, so...

Will these work on my 1964 with original engine? On the Denso site it says no parts available for that year.

What should they be gapped at? I see .31 and .39 on Mud.

Also, torque spec?
