tune up time

[p71towny]

no bosch platinum +4's they are garbage.......i've had customers insist on them only to get crappy fuel economy 16 mpg out of a 3.3 caravan after those plugs.....after a fresh set of autolite double platinums 24 mpg.....for teh panthers...............autolite or motorcraft coppers are the best

Scott is right on. Those plugs are the biggest pile of shit I have ever encountered. I have not found a car they work well on. I refuse to put them on anyones car when they want a tune up.
My favorite plugs are my motorcraft double platinums. I have yet to find a better plug. I've run em in a 5.0 with no problem but they're really for the 4.6.
