I here 2 or 3 steps colder spark plugs, yes? But when it comes to the wires whats the difference? Why does one cost $37 and another $160? Thanks

CFM recomends one step colder for every 50 hp you increase over stock. Majority of the FI cars are running the Motorcraft azfs22c not the $44 Denzo's.
Most aftermarket plug wires are around $50 for a set of four. Some sets include a coil pack and go for around $150. The $160 Nology set is something I'm not familar with.
I like the Screamin Demon coil and Live wire set.
