spark plugs and wire upgrade ???

[99steeda]

Would it be smart to buy upgraded spark plug cables and plugs. Would this increase the HP or fuel efficiency or would this be a expensive way to make my engine look good i am more interested in doing it for the performance gains
Thanks for any info

No performance gains are to be had by multi-electrode plugs, fancy colored spark plug wires, or ANY after market ignitions, or coilpacks! Stay with the
recommended Motorcraft double platinum or finewire spark plugs, a high quality spark plug wire set, like NAPA customs made by Beldon, and stay with the Ford EDIS coilpack.

+1, You will not get a performance "increase", but you will keep it from having a performace decrease. Multi prong spark plugs are a scam plain and simple. Electricity will follow the path of least resistance and NEVER spark all the prongs at the same time like they try to get you to believe.
