the charges do add up why don't Jegs/Summit carry these wires ?



Take a look at Summits house wires - 8.5MM same Delphi wire - you just don't get the custom fit and service - but they are made from the same wire.

Personally I have used ULTRA 40's for years – but it was not until I switched to a digital ignition that I noticed and impact of RFI from the wires themselves - RFI is a much more complex discussion than ohm’s per foot – But in the end it comes down to personal knowledge and preference and what works best for your rig – the computer controlled fuel injection cars require a whole new set of rules – something companies like Delphi have extensively engineered and tested over the last 20 + years – hence the reason wires on new cars last almost the lifetime of the vehicle.

We have come a long way from the yellow jacket wires of the 60's
