spark plug wires

[RDR]

whats th stock size in wires and do thicker wires really hlp Fuel/prformance?

Good low resistance wires always help in overall performance. You get a crisper spark and with high voltage ignition systems they last longer. It helps also to add dielectric grease to the wire ends any corrosion will add resistance affecting the spark

Good plugs gapped properly help alot also. Motorcraft/autolite platinum and change the PCV regular improves MPG.

Stock wires are fine for just about any mod. The larger wires are only for show. American and Asian vehicles run on voltage. You don't need larger wires to run voltage. If you had a European vehicle then you'd want bigger wires since their systems run on amperage.

Bigger wires get you nothing in performance nor MPG.

I agree. When you switch brands away from Motorcraft/autolite you can be asking for trouble. Some stuff might work fine, but with others- you'll be replacing all that crap again because it won't run worth $hit.
