Is this really necessary or can you buy a Cold Air intake system, a SS Crank pulley, a Header, and some fire racing spark plugs and call it a day for a much, much, cheaper price. No need to buy a bigger exhaust the company that furnishes my car has a decent sized exhaust, so know need to buy a bigger one of those. Anyway, are those 3 things basically all I need and really don't need to buy a supercharger kit for maximum power performance for my car?
