"make sure they are Denso or NGK. None of those German platinum or "650 billion VOLT, multi-electrode X-TRA spark" shenanigans you ordered off the internet after seeing them on some hillbilly car show you saw on a Sunday morning." from 22re performance.com

I have read on many automotive sites, Toyota and other manufacturers, that there is an issue, problem, or some other performance failure thing when installing a Bosch spark plug into a Japanese engine. And.. that the Bosch spark plugs work fine in a German manufactured auto, like a BMW or Porche. I do believe there must be "something" to this?

My problem is I have NEVER read or heard about anyone or any organization providing ANY support, test data, dyno tests, or actual spark plug to spark plug comparisons to technically or scientifically explaining why a Bosch spark plug doesn't work in Toyota engine! WHY??

Does anyone have any certified data or any information from any reliable source that will substantiate and support these claims with facts?

If the guys at 22RE Peformance say "only use Denso or NGK", I would just like to know TECHNICALLY WHY? For example... if a Bosch spark plug failures prematurely (10K miles) in my 22RE and a Denso spark plug works fine for 50K miles - WHY?

No... I don't have any Bosch stock in my stock market porfolio.

Gnarls.

Only data I personally need is My own experience. I have seen it more than once.
And apparently so have many others. that's enough for Me.

Well my experience is that the Bosch work great in the wife's 4runner, and my 2000 Tundra( both 4.7L V8's). They also worked great in the honda I drove. Both are not German motors.
Only time I had a problem was some Denso in the 4runner. Though I am not sure it is/was simple the plugs.

Guess I own two unicorns. Bosch plugs and they run great. Dealer plugd and the 4runner ran like

. Only one's that posted on those two threads said bosch does not work. How many guys are using bosch, but don't have time to sit and post hate cause they are too busy having a life.

Well I could hand delivery them next time I drive past your place to one of my Seattle drops. But that would likely not be till the spring.

Well time will tell if I can arrange it. Just can't do it if my load is going to Kitsap, but if you don't mind a driving a couple miles...

Worse misfire I've ever had was with the original bosch platinums (they had the teeny tiny nipple of a center electrode) in a Mazda 12A rotary engine.....

WOT above 4000rpm and it just fell flat on it's face.

Did they say it was over torqued in a Toyota like engine application?

No it was a carbon build up example. The electrode was nasty.

The plugs out of Karens 4runner had carbon all the way up the threads, and a ring of it around the area where the Hex body meets the top of the threads on the cylinder head.

Bestgen has me convinced the plugs are not likely the "main" reason for the problem, they may be a part of the problem or just another symptom of the problem. Since I reset the fuel map and things I can only wait to see if the problem reappears in a few months.
