Platinum is ONLY for longevity and you will find VERY few of us serious about performance bother with platinum.

Ok, so what your basically saying (if i understand currectly) is it don't really matter whether its standard or platinum unless your looking for longevity, thats not an issue to me really (unless it affects heat range), i don't mind spending 2.29 for a platinum NGK, just wondering if the Autolite might be a better choice, i guess i'll stay with my first choice with the NGK TR55s, they are Platinum & were spoke Highly of on this board.
