Yes, he is saying What the eff. It matters when you want to get the most out of the car. With the proper wires, plugs and coil. You'll get better milage, more power, better overall performance.
Cheap wires you get subpar performance to less of what the engine can actually do. You put on. A CIA then say who gives a crap what wires and plugs I use?
Honestly you should and your car would love it. Massive has performance package for the spi which gives you larger 8mm wires, MSD coil and motorcraft cooper plugs. It's very affordable and you will have the top of the line performance out of your ignition system.
If you don't want to opt for the ignition package, you can just get the 8mm wires from massive you get a stronger and more reliable spark. They are cheaper that those subpar wires you bought at autozone.
To top things off they come in various colors to help at some character to the engine bay.
