    I'm going to replace the wire for my spark plugs, using the factory terminals (they come apart). I use resistor spark plugs (NGK DR8EIX). I don't have a radio in the car, nor do I intend to. What's the best 7mm wire to use?

    Hi!

    I don't have much experience with the F129B-C engines but knowing the stock ignition is a static electronic ignition I just want to know what you want to do with the car?
    Will it see track a lot or it would be driven mostly on street?
    I have a couple suggestions for you depending on what you intend to do with the car and if you plan any modifications to the engine/ignition system.

    As long as you don't switch to a more powerfull digital ignition and race under extreme high heat conditions most wires on the market will work good.
    Stay away from solid copper core wires, even if they are the best you don't want any interferences.

    I would go for a set of Bosch wire 7mm or you can go a little bit bigger with some 8mm like theses which is your best option: 8mm Pro Wire Race-Fit Ignition Wire Sets - Taylor Cable Products
    (Stay away from TCW)
    Been using them in past and after testing the resistance vs RFI (Radio Frequency Inteference) + EMI (electromagnetic interference) they worth the investment.

    Magnecor wires are also good
    Magnecor Race Wires

    You can also choose 10mm wires which are more designed to use with digital ignition if you ever plan on modifying the stock system let us know if its the case.

    Have fun!

    Google on the Bosch number. As I recall, last time I did that you could fit two sets from a Fiat Croma. Bargain.

    I used a universal V8 "high performance" wire set from Autozone. Just removed the copper fittings that snap into the ignition module from the original wires and crimped them on the new ones. Runs great. Less than $50.00

    Mitchell - did you use the same boots? or get new ones? The boots are the costly part if you go with direct replacements.

    The 348 boots at both ends are reusable. You buy the bullet crimps from Kingsborne for cheap.
