Bosch Platinum Plugs ...anybody ever use these.....just bought some for a good price..always used ac delco before..... .50 gap ??
They are crap. I know I've used them on my V6 and it was crap after few thousand miles(misfire). I switch to iridiums after that.
And yes, my coils were good, wires were good, vaccum was good, fuel filter was good but the plugs were bad.

+1 Agreed. Never had luck with these things. All marketing and no performance.

I am going to have my plugs replaced in the next few days and am not sure which ones I am going to use yet. I did a few searches on plugs and it seems like most everyone agrees, NGK TR55 is good and the Bosch is not. I particularly do not like Bosch myself.
I have a 2000 SS Camaro and I believe that AC Delco Platinum came stock in these. Please correct me if I am wrong.
Well I guess what I am getting at is almost everyone recommends the TR55. These are a copper plug. Isn't the platinum better for various reasons? Is the reason that people buy these because the are an all right plug and they are cost effective?
I also read somewhere someone having problems with the Iridium plugs.
I think I am going to go with the AC Delco Rapid Fire which is a performance platinum plug or the AC Delco professional platinum.
Anyone have any comments on these?

Just took my factory Iridiums out in favor of the NKG 55's. I had to listen to a lecture from the a-hole at Napa about why I should use Iridiums but I plan on replacing my plugs every 10k or so and I'm not wasting money on the Iridums. I gapped mine to factory specs for my 02 which is .060.
