bosch platinums

talk to anyone who knows about mercedes or bmws and they will say the same thing...platinum plugs are not only junk, they could in fact harm your engine..remember bosch was in league with lucas at one time so they are not without doubt at times...never use platinum...pure marketing

ridiculous platinum plugs last 100k single side electrode ngk 7090 bosch 7422
 

I build,race and drive both makes.ohlord

So if anyone knows it is me.

Where do people come up with this crap

bosch platinums are junk...look at any owners manual and see, the cores crack very easily and cause misfires....

ngks are even worse...just stick with what the manual says...don''t get fancy is my advice.  i had a bmw 635 that required silver tips...$10 each...tried to bypass them and didn''t work...had to pull them within a month a do the right thing 

all has to do with heat rise and decay...wrong plug..wrong result

Bosch platinums are what the manual says and NGK are also listed as oem.
we are talking about the m112 ans m113 engines are we not?
Earlier copper plugs were fine in the early engines.Stick to them if that is what you are talking about.The modern high compression long fss interval engines run great on platinums single side electrode.

Bosch platinums are junk????????????????
I run them in all out race engines,never a failure.They are oem plugs in all modern Mercedes.
I am afraid you have no knowledge at all to back up your  claims

what are the benefits of using those plugs?

What model car and engine?platinum plugs oem on most 98 up mb engines.Longer life,less wear,gap stays constant over the change life of 100k miles.ngk7090 are $2.79 each and you can diy your own plugs on the 320,430,55,230,280,300,350 etc.
just check application on ngk or autohausaz.com and stay away from the multi tip plugs,they are not needed.

i guess i am speaking towards older bmws and mercedes then.  1990 and older, sorry i reckon.  i don''t know about newer engines, perhaps platinums are fine for those 

I take back everything,you have an open mind,and are correct about the older engines

My local mech pulled my plugs last month as a courtesy to see if they were looking good.  He asked if I had replaced them recently.  I replaced them 60K miles ago!!!  Bosch Platinum plugs work just fine for me.  Nothing fancy, just the regular Bosch Platinum plugs.  My mechanic said that I should be find for another 40-60K based on what he just saw.  I hope to report my 100K mile findings in a year or so.  Take care all!  O Lord and Cliff... be nice!!!!

thanks ohlord..appreciate the consideration and acknowledgement regarding my oversight...only goes to show that reasonable minds can co-exist... so, that, aside...

Het Scud,
you a submariner?
what boat?
