Hi Everyone,

Doing a tune up and should I go with Toyota or Bosch Platium plugs?

TIA,

I have personally had problems with bosch plugs in a couple different Toyotas including my FJ40.
I only put Toyota OEM in now. They are a U groove plug anyway, and seem to last a looong time.

Just pulled the Champion plugs out of a non-running 77 FJ40 and replaced with OEM, ran better immediately, then much better after performing the magic hand slap on the carb. Maybe just me, but?????

I have noticed that the build of the OEM is different than aftermarket. This affects heat range, etc. Maybe thats it.

I just feel the OEM *works*.... and ya know what they say about things that work! :D

PS: NGK are an OEM crossover (even in the manual) if you're not at a Toyota dealer.

Nippondenso spark plugs do perform best in Toyota vehicles.

I also run them In my 440 Magnum 1970 Challenger and in my 4.3 GM powered boat.........


Ya just can't beat 'em..... :cheers:

I've used bosch platinums with no problem. They need to be replaced more often (60k vs 90k) but at 1/8 the cost of iridiums it is worth the extra hassle to me.
