HT lead set for all Rover V8 powered TVRs. For TVR Chimaera, Griffith, Tasmin and V8S, these leads are designed for extreme high temperatures, so this lead set is ideal for those hot under bonnet applications, especially those who suffer from failed HT shrouds. The ceramic spark plug caps have been tested to over 1000 degrees C so should be ideal for road and track applications. The set comes part assembled, so you can decide your prefered lead route, then cut and crimp on the distributor cap ends of each lead (terminals and boots are provided). This means you can omit the TVR E0142 NS HT shrouds. Please remember that the ceramic caps can be delicate if manhandled so treat with care but this is probably the best ignition lead option for the Rover V8 engine especially if modified.
