Pure BS....Mine worked fine... Pure BS to those that say there bosch plats caused them issues..
maybe you installed them wrong or something..
Mine have worked great....lots of miles...and smooth idle always..
I cant believe someone says that Bosch plats are bad...
there may beothers that work better for a certain applications..
But there is nothing wrng with bosch plats at all for a basic ls1

I will say this with experience as a professional mechanic.....All Bosch spark plugs are trash and should not be installed in ANY engine. I have seen MANY different problems with Bosch plugs, including melted electrodes, broken insulators(INSIDE the engine), and some brand new plugs that CAUSED mis-fires. Seems like when a car comes in with a driveability problem, Bosch plugs are the problem 95% of the time. And as far as "indexing" goes...yes it does work on regular plugs, but not when you have 4 electrodes shrouding the spark. The point of indexing is to provide an unobstructed path for the air/fuel mix to reach the spark.
I can't say anything about NGK's because I've never used them, but they seem to be the plug of choice for internet LS1 gurus. My vote goes for AC Delco plugs in any GM product, they may be stock, but they have NEVER let me down in any GM application.

Yep I totaly agree with this statment Bosch are junk. I'll recomend AC Delco Iridium plugs their 100,000 mile plug thier about 6 bucks a plug at the store ( find them online for cheeper) but they are a good plug.

I can't personally see how one platinum plug would be worse then another. Platinum is a sister metal of Iridium so if platinum works improperly iridium should respond the same way.
I've always been the type of guy to give new things a try. With all the hype of the TR55 and TR6 plugs I tried them out and noticed a stumble, or "miss" at idle and the car didn't feel as snappy with the copper plugs as it did with the TR55ix spark plugs I replaced them with.
Having recently tried out the WeaponX K6CF Extreme Iridium plugs I noticed a large difference over the TR55ix spark plugs in idle and engine response so I firmly believe a proper spark plug design is advantageous to the engine. I can't comment on the Bosch but I can say if I don't need to replace the plugs as often with an Iridium or platinum design, it doesn't hurt my feelings. #8 sucks to get to!

lol... I don't know how I dragged this up. I was looking for opinions on spark plugs other than the NGK stuff. I was hoping to see feedback for these new ones I just installed as well. No luck, but thought I would post some feedback.
