Leads?

Does repacing all your plug leads with performance ones make any difference?

replacing your current plugs with "hotter" plug will always help.

Unless you have issues with your current plugs you will not gain any noticeable improvement on a NA engine. I have seen improvements in supercharged/turboed cars but on a Cougar you can't expect to see much if anything. Stick with what you have or if they are higher mileage replace them with a set of double platinum Autolites or stock plugs.

Just put a set of performance leads on and there really is a noticable difference in smoothness of the ride (unless I'm just wishfully imagineing it).

If your previous wires were bad/old then it would increase the smoothness of the ride.
