Just a little more on Bosch Platniums.
Here is a post by a member of my forum asking about spark plugs, edited for space.
"Hey guys, wanna run something by ya. I changed out my plugs with bosche platinums and a friend of mine who has owned several buicks including the GN told me that gapping them was not necessary. The guy at the auto store told me to gap them at .060. My friend said that as long as their is no obvious difference in gap size between all 6 with the naked eye then they should be OK. I went ahead and took his word for it and installed them as is. Now my T is having a ***** of a time starting in the cold; it will fire but not all the way to running. After it warms up and has run for awhile, it will start back up just fine.... Pretty obvious to me but what do you all think?"
My response:
"Bosch Platniums are a bad plug for GM's DIS. They will wear quickly due to the high voltage of our ignition. Rapidfires are a good buy for the money, so are GM's double platniums..."
His follow up:
"ok, about the spark plugs...BOSCHE platinums suck A**!. I took the advice from this board and installed AC Rapidfires (bosche only had 50 miles on them at swap out) and it started up at 12 deg F outside without skipping a beat. Thanks, fellas. I'm happy now....."
