Bosch Platinums are some of the most overrated plugs ever designed. They are more a gimic than anything. With NGK's they are more specifially design for a Probe....as long as you make sure to get the correct part number. NGK's arent as expensive as the Bosch's are either IIRC.Harmony said:Bosch Platinum 6. About $5.99 a piece, but they're are worth it. I doubt I'll be using anything else unless convined otherwise.
Oil in the cylinders (beneath the spark plugs) or oil in the spark plug well? The latter is most common on our cars, and represents a leaking valve cover gasket.kronix said:i also have a question......... i had some oil in pistons 1 & 3 i believe........ worn piston rings?
NGK spark plugs are around 2 dollars a piecegurlsrace2 said:yea putting in new spark plugs isnt going to make any noticeable difference unless your car really needs a tune up .But if you are looking for better performance ,ngk spark plugs and spark plug wires would make a slight difference.NGK spark plugs are like 10-12 bucks a piece,so dont waste your money unless you are gonna go all the way and do ngk plugs,wires and msd ignition.
