I went to a dyno day this past Saturday and learned my mustang is more like a foal. That being said I want to start with a basic engine tune up since I know it hasn't had one in an extremely long time, if at all. I have stock plugs and wires to my knowledge, what is a good recommendation to replace them with? I plan to get this in a month: https://www.americanmuscle.com/sr-cai-75tb-combo-9495gt.html so I do know if that would benefit from any particular plug/wire combo. Either way I am sure they need replacing.
