I am almost at 125,000 KM and I am looking to get a tune up done. I was looking around on here and see alot of people saying that MSD ignitions are a waste of cash and that the GTP coils, wires etc... are better and cheaper. (And I love cheaper) Where is the cheapest place to order GTP coils, wires, etc.... And also IYO what is the best plug to use?
