Bosh Platinums
-
id rather spend the 20 minutes every 8000 miles or so to change my plugs, especially after this, and i wont go back to these rediculosly overpriced things, a lot of people are right NGK is a very good plug, i have used them in snomobiles, atv's, motorcycles, and lawnmowers, they always work great. I just thought that this is not a racer or a beater, this is my weekend toy, platnums may be the way to go, apparently not for the price. I have never seen standard plugs fail in this way before, i have seen the gaps, or bridges (whatever you want to call them) missing before, usually in snowmobiles from shrapnel lol :icon_scratch:

have you pulled the plugs out of a new car at 50-70k miles??? I have a number of times, and more often than not, that awesomely sweet ass platinum disk is gone anyway. Thats right, i would love to have that nice little piece go through my heads and try to take out a valve. seriously ive taken platinums out of 50-70k mile motors that you would swear had been in there for decades, they looked horrid. Oh, and when the platinum falls off, guess what, you have an electrode with half the diameter thats wearing faster than shit.
BTW, copper plugs last on average 30-50k miles, so i dont see what the big deal is, for me thats a plug change every 3-5 years.

If you have the right plug the platinum will not fall off, Champion in particular uses a laser to "weld" the platinum tips on, thats why AC Delco doesn't make their own platinum/iridium plugs. They buy them from Champion and NGK then put AC part numbers on em. I have changed plug on a few cars that had 100,000 on them, one of which was mercury mystique and a couple of GM 3800's, and the plugs looked no worse than the one I pulled out of my Cougar that had 25,000 on them. In the case of those engines you absolutly cannot use copper plugs, the waste spark ignition system will destroy those plugs very quickly. I can't count how many people have come into my store with a Grand Prix/Bonneville/Buick 3800complaining about a miss, claiming they just changed the plugs. They bought copper ones and guess what, 3,000 - 10,000 miles later the plugs are shot. Who wants to change those plugs all the time? 3800's are a PITA. Even using the motor mount trick they still are not fun at all. I can change my plugs in no time, as I'm sure some of you guys can, but a 3800, or a ford 2.5 V6 take a little more time.

Well we will see what happens, I got ahold of a Bosch rep today, he is starting a repair claim on the car, he said they may have it towed to Valley Imports since that is the mercedes dealer in the area, and have it looked at and repaired if nessecary, he said the platinum electrode may have done some serious damage to the block and internals if it hadnt been 'spit' out the exhaust, and i told him that is my fear, cause the engine had just recently started to burn oil. so im keeping my fingers crossed.

They'll make it right, unless they can pin some, "The plug was not installed properly" bullshit on you.
