Been putting off a major tune-up as catching up on some bills and our two major purchases last October. Which actually I had scheduled a tune-up with my friendly Dodge dealership but went test riding two days before and ended cancelling that appt. But at 97K miles it was past due plus I already had the parts on hand. Champion RC plugs, MSD plug wires, screamin' demon coil packs, lower billet pulley/belt and All-Pro manifold gaskets..most of which I got from JTSVP. Plus I added on an oil change and tire rotation since as it was already in the shop. With a 10% off discount coupon..it all came to $585.00 with tax..I can live with that plus added a few more HP in the process.
