What Spark Plugs?

[joef]

Hi Guys,

After setting my timing and points gap (thanks for the info) I still suffer from poor starting when the engine is cold, i have to pump the throttle loads to coax it into life. Onces started its fine.

The spark plugs have about 8000km on them so I am going to replace them. Can you tell me what plugs a 1993 with a 3F engine should have? If you could give me few options of makes and code numbers as I am not sure what I will be able to buy in Ecuador.

Thanks in advance

Joe

Factory recomended NGK's.

The autolights tend to foul easy.

Factory plugs are Nippondenso I thought. Ive used any good quality plug like NGK or Bosch with no problems.
The Bosch were Super type and the part number W8DC.
I had these in the 3F non efi in my FJ73 for over year as it lost compression and used oil. Never fouled the plugs though,they are still a beige colour with 20000klm

I only run NGK in my 2F. I think the ones I use are BPR4EY.

The OEM factory plugs are Nippon Denso, and they are cheap at the dealer.

NGK BPR5ES-11 is listed as a standard replacement

Other NGK plugs available. You can use their parts finder here http://www.ngksparkplugs.com/part_finder/car_truck_suv/default.asp

Ive use bosch. but regular bosch. I tried those platinum 2s. The were more in price, of course but i figured what the heck, i love my 60 that much.
i noticed no power increase or mileage change.
just some FYI on MHO.

Factory is Denso W14EX-U

NGK is a good plug, though.

The NGK and Denso plugs look identical. And are what I stick with. I will not use Champion or Autolite.

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.

snake oil..

I have tried both plugs. Not any better than a cheap set of champions or NGK.

I tried the bosch platinums...got a rough idle from it.
Stuck the NKG's back in there...
solid as a rock!

As I said; I have used every type plug on the market at one time
or another over 30 years; Truck plugs, StarFire, Spitfire, Autolite, Champion, Bosch Platinum, NGK, ND, and Iridium.

For my FJ-62, the standard Splitfire gave me a tad more power than
the ND OEM plugs, but not much. Bosch Platinum were the worst.

For my FZJ80, ditto; tried them all; the Denso IRIDIUM work better
than all the others; smoother idle, better acceleration and gas mileage, etc.

If you do a Google search and read about the Iridium plugs,
they need less energy to make a hot spark; so if your electrical system is getting old, they should work better in wet or cold conditions.

Worked for me.

Just slapped a set of the NGK Iridium IX plugs in my 62 and found this thread while looking to see if anyone else liked 'em. These are great. Idle is far smoother and acceleration is as well. Haven't driven enough to notice if they improve performance or not (I'd be surprised if they do, but the real test is how long I can hold 65MPH going up Sunset Hill here before I have to downshift. The Spokane guys know what I'm talking about), but we'll see if they last as long as they claim, and if it affects my economy at all.

You should see an improvment in Idle quality from replacing any sparkplugs.

Get some Denso or NGK's and do the exact same thing.


Let us know if there is a significant difference.


(and, make sure that the plug has the correct heat rating)

Heat rating is the same as the basic NGKs that I always used. I usually clean my plugs good every year, and replace every two years, so they're never in bad enough shape to make new plugs seem so much better. These were an easily noticeable improvement though.

Now to see if they actually hold up.

My spark plug testing ground was several years of desert racing motorcycles. NGK never let me down, neither did Nipondenso. I have seen plenty of Champions (a misnomer) puke out as well as the Split Fires. Granted, racing a two-cycle motor off-road is far greater punishment for a plug than will likely be seen in a Land Cruiser, but just the same, NGK is all I will run in anything.
