grounding kits really only see their biggest (or any) gains on older efi cars. if you have a 91 civic si in your driveway go ahead and buy that grounding kit you saw in a super street, because it is basically a secondary ground system to replace your decades old and corroded factory grounds. on older cars they take a little bit of noise out of the sensor signals and improve spark that is where you get benefits from. if you have a good factory harness with clean connectors, and good signal it is a waste of 100-200 bucks

^^^ Bingo.

And the fuel magnets do nothing... well, they might cause some ECU interference

Also, speaking of magnets -- the folks that use the magnets on the oil filters -- isn't our block aluminum? Am I missing something?

the alluminum block kinda makes it seem funny but you have to remember that our timing case is flushed with engine oil so the materail wearing off of the chains and sprockets will get flushed into the pain. and when pieces of dirt or casting sand manage to work their way into a bearing they can rub material off of the crank and cams, also there is minute wear of the lifters and lifter to rocker cam things(whatever you want to call that on vvel i'm to lazy to look it up right now). also the oil pump wears down over time as well so there is iron wear in the engine to what degree who knows but thats where the iron count on a UOA comes from molecular iron particles floating around in the oil(which are often times much smaller than the pores in the filter media and are basically harmless but serve as a good wear indicator).
