Hi there. I have a 98 V70 5 speed naturally aspirated wagon. Everything except the paint is in mint shape with single owner records from new until a few months ago before I bought it. The car was babied but they must have had animals all over the car because the pains has scratches all over. its the weirdest thing. Anyways, I am very happy with the car, I will have it repainted and was wondering if anyone knew what I could do to get a little more power from the engine? It sounds and runs great, it just feels a little heavy from the start and then the power rushes in at about 3000-3500 rpm and up but overall it just feels heavy. Are there any computer chips, or cold air intakes or anything that can be done to add at least 15 or 20hp to this engine? Also, what are the very best plugs, cap and rotor I can buy for this car?
