ECU custom roller & bung

1 x custom rollerwheel and colour matching speakerbung for the ECU alarms

You will notice our custom rollers for the ECU alarms are made differently to the originals – we machine our rollers and mag with a higher strength single-sided 4mag contact for a more “traditional” style – these are of higher strength to that of the originals, ensuring these work with the sensitivity function of the alarm correctly – Price shown is for 1 x roller & speakerbung
