    How reliable are the coils?

    Anyone ever had a coil go bad and what happens when they do?

    We had one fail. The insulation split and the effect was similar to a bad plug. I did hear that there was a suspect batch around in the UK

    Rxp Coils are one of the best coils on the market

    Coil failure is caused from a lot of things

    1) If you keep removing them and putting them back in with force in the procedure you might be likely to damage it.

    2) I f you are running an after market ECU and you are running too much Dwell Time the coil will over heat and melt.

    I use an igniter with the RXP When running motec. I can also use CDI Ignition on that same coil.

    I have seen this same coil on Drag cars Running over 2.5 bar of boost with the use of CDI Boxes with out any miss fires or failure.

    I f you want to know if a coil is damaged. an easy way to do it is
    start the engine and remove 1 coil at a time (Do not remove the connector) if nothing changes when you remove the coil that coil is damaged.

    Check out this picture where have you seen those coils before lol

    This car is using M & W cdi box with the RXP coils it is making close to 1450 hp
