Frequently Asked Questions


  • Do you offer custom spark plug wire sets?

    Yes, as long as we have the correct boots/terminals, we can quote you for a ready to install set or universal set. Most custom sets will be available to ship in 1-2 business days.

  • Are there any warranty on your products?

    Yes, our boots and terminals will come with standard warranty for defects and a replacement will be sent. Custom wire sets or ready to install wires will come with standard 1 year warranty from purchase date. Any alteration of our wires will void the warranty.

  • Do you accept returns?

    Custom ordered wire sets will not qualify for returns, but unused parts purchased from our store will have a 20% restocking fee and we do not offer return shipping labels unless it is under warranty replacement. Please send an email first at tonsperformance@gmail.com prior to returning anything.
