I acquired a 2001 Bone Stock GTP one adult owner car. This car has never been hurt. I wanted to do a tune up and some early mods. Will these hurt or help: ACDELCO Iridium plugs, Accel Coils, MSD 8mm wires. I also am thinking about Dynomax exhaust (I don't want loud just opened up) with SLP GTX Tips. Also looking at SLP GTX cold air induction.
Please let me know if I am wasting money or not. Thanks
