Been useing Bosch platinums. Don't like them. They're cheap, but they don't even seem to last eve 20,000 miles. The platinum electrode errods. I know thats what the electrode is exactly not suppost to do, but thats what it's doing. Thinking about finding a set of silvers, or maybe some type iron cored plugs.

I don't like multi-point electrodes. They do nothing for power, and are ment only to lengthen the time between plug changed. However, they are also impossible to gap, so you get what ever the factory gives you. Belive it or not, not all cars are ment to have the same plug gap.

I'm not too particular about spark plugs brands. Most of it seem to be religion more than anything else. As long as you've got the timeing set right, all you need is a simple spark. Everything out there is geared to delivering that continous, accurate spark. I haven't seen a claim for a set of plugs that it outside of a few percentages points, which is more often than not well with in the error of the dyno. Not saying they don't exist, but they sure arn't makeing ti clear that they excced the possible error.

Although Bosch and other plug makers do us the service of pre-gapping and protecting with that little plastic piece, don't trust it. Check the gap yourself and adjust as necessary. You don't know where that thing has been.

As ViribusUnits says, the chain-store platinums' electrodes quickly wear out. It's all marketing. Not to mention just plain bad out of the box sometimes. The "true" thick-electrode platinums and Bosch Silvers are worthy plugs. And also pricey. Pay me now, pay me later (PMNPML). The Supers are best bang for the buck and the Japanese plugs I certainly would not thumb a nose at.

And do not try to gap multi-electrode plugs. They are not supposed to be gapped.

Going in today,

MY '85 928 application.
Although these are presumed to be pre gapped, what is the recommended gap?
Also what should they be torqued at?

Put your manuals away, I found it.
