Ok, it's been a while but after 70k plus miles on the Av and warranty has expires I've been contemplating buying the multi-spark coil set for 8.1l from Summit. I've aleady ordered the wires after reading the all the positive reports on the 1500's and figured that the stock wires need replacing anyway...but haven't read about anyone doing this for the 2500's or about the coil package. The coil packs are $631.00 a set of 8, the wires are the same ones for the 1500 as for the 2500 @ $64.00 set..inflation since the last post in '05. Anyone have thoughts?? Or have done this mod? Should I...or shouldn't I...I guess it's all the same when the lights go out.
