These are custom made MSD 8.5mm plug wires with specific lengths for the Mitsubishi 3000GT / Dodge Stealth with the 24-valve DOHC engines - both AWD Twin Turbo and FWD Non-Turbo. These offer a much more affordable option versus the made-by-MSD sets - the only difference is these wires do not have the hard plastic shaft going down to the plug with the rubber cap around the top of the plug opening. Buy with confidence - we have sold over 1900 sets of our custom made MSD wires!
