Bosch platinums

[Flight_740]

Are these plugs really that bad? Primaraly in imports? Everybody at the nissan board insists they are junk. What are your thoughts?

[1quickgtp]

they are right, there JUNK

[DirtyMax]

I never had any problems with them in any car I'd ever tried them in.

Now I don't keep trucks long enough to need to worry about plugs.... :D

[juicedimpss]

i wouldnt use them.

[junk mx6 no rly]

there complete junk my friend had them in his 2ndgen probe made it backfire and shit absolute pice of shit plugs.switched to autolite copper ran perfect.even when there was only 1 bosch in it it made it run liek shit backfireing and everything.autolites or ridiums is the way.:thumbsup or ngk plugs are good also.

[Flight_740]

If they are so bad, how are they still in business? Do they cater to the German imports more? Thats all MB seems to Run. I have been strongly urged not to use them in my Q. Well, I did and they worked great for 20k. Now the car runs like crap and I'm wondering if thats the problem.

[rally_scort]

there still in business becuase of people thinking that platinums will last longer,burn hotter,etc.It really depends on the car too, i had em in my ranger and they worked fine but i also had them in a probe i bought and it ran like shit like mentioned above.I pulled the plugs,checked the gap and it was fine, the plugs were only 1 month old.Id say if you want some better plugs that will outlast copper plugs and burn hotter get ngk v-powers.Ive had them in a last few cars ive owned and never had a problem.I also remember a kid in auto class in high school who used bosch platinum +4s in his feiro and it burned through the head.:rolf :rolf

[jbiscuit]

they are REALLY bad. NGKs all the way.

[Slow Joe]

Hrmm I had 'em in both my Jeeps, and put 'em in a friend's car with no problems...

[Lash]

They are yucky!

:goof



No...really...they are.

[DirtyMax]

Wow. Sounds real hit or miss. Funny two people mentioned them having problems with them in Probes. I has two (1st and 2nd gen) and those are the cars I ran them in. Both with no issues. But I think that's before all this +4 crap. Maybe that's the difference...:confused

mine were 1 month old standard platinums and it wouldnt run for crap on high rpms and would die when coming to a stop.

[Slow Joe]

I put the +4 Ones in my Wrangler...

[WilliamZ]

I never had problems with them. I heard not to use the Platinums in boosted cars.

or when your spraying is what i hear also.

[BigSnailBuick]

I know when I tried them in my old GSX they were garbage. Imports love NGk's, I love NGK's. :banana1:

[BadAzzGTA89]

There crap!
I run Rapid Fire's!

[Junky Giorgio]

Junk! >from the "junk" specialist himself :rolf

[Feature Pony]

NGK's are pretty good, since they come in most import bikes that spin up to 13000rpm so they have to be pretty good.. The Bosch I had them back out of my 2.2 turbo all the time untill I threw them down the street and then I ran Champions.. The bosch work good with the VW and BMW cars but I guess its more of someone's opion.

The only plugs I have ever seen cause an engine to run like SH*t are Bosch Platinum’s, and any other 'multi' tipped plug they have. Now, all of those cars that were running like sh*t didn't come with Bosch's, let alone platinum’s. So here's my thought on Bosch Platinum’s, I don't think they are outright junk but I think they only work in certain applications. Most people would be surprised how much a different style, heat range, or brand of plug can change the way an engine runs/performs......

Just my 2 sense......:headbang

I like autolite copper plugs. basic. a buck fifty each. old school sometimes works better. from what ive been taught, copper is an excellent conductor. never heard anything about platinum being a good conductor, besides, lets just say the platinum does last longer, who cares, the autolites are only a 1.50

[Moparjim]

Copper is a better conductor. I use and recommend using plain old copper plugs in anything high performance, and definitely in anything boosted or sprayed. Boosted or sprayed = high cylinder pressure and a lot of times you will get spark blowout or they just won't fire at all with platinum or other plugs. Platinum is not near as good a conductor, that is one reason they are a pin point (cost of platinum being the other). Sharp edge or point is a less resistance as well, the platinums need all the help they can get.

The reason manufacturers went to platinum is for one reason only - it is harder and does indeed stand up to heat much better so they last longer. Hence the manufacturers can advertise 100,000 miles or whatever before needing a tuneup. Anyone with a high performance car should typically be changing plugs quite frequently and the coppers are only a buck or two each so screw the platinum.
