Better to up octain and increase timing.

If you drive your car hard don't expect miracles from even 89. The owners manual wasn't written for a race car driver. If you want to put the pedal to the metal often, USE 93!!!!

Performance driving requires performance octain to prevent pre-ignition.. that's just the nature of the beast.

87 burns faster but you'll knock more... 93 with 0 knock and more timing will make you more power. [img]smile.gif[/img]

i have the bosch platunum +4's. i have had them for over a year. i havent had any problems with them yet. im sure they didnt hurt my performance, in fact feel they helped

get the +4's outta there.
plats burn hot as it is, having extra tips (only one hits at a time) only makes the plug hotter...and can lead to heat outside the combustion chamber = pre ignition = KR. even with 93 octane i was seein 8* at the top of gears.

plat is hotter than copper at the same heat range.
lots of plat (+4) is very hot.
i run coppers...it's worth it, at least in the summer. almost 0 KR with them during summer. not a very hot spark in winter tho..of course, we HAVE winter in cincinnati ;)

edit = Plus 4 is a gimmick. it's a longevity thing, not more spark.
