Ignition 8mm Cable data sheet
Silicone Reactive Core Cable
Ultra Sparks Our own-brand premium cable used in the majority of our high performance lead sets.
The core consists of a fibreglass base coated with a ferromagnetic compound and tightly wound with a stainless steel resistance
wire under a coat of conductive lacquer.
The design ensures maximum spark quality with minimum voltage loss while maintaining excellent Electro Magnetic Pulse suppression.

Resistance: 5.6kOhms per metre (nom) as standard
Reinforcement: Glass fibre braid over insulation
Test Voltage: 8.0mm dia Silicone - 35.0 - 40.0 kV RMS BDV (typically)
Specification: Fully approved to ISO3808:2002(R) Class E Type 4
Termination: All lead sets use brass, beryllium copper or stainless terminals with silicone or EPDM connector covers,
many of which are sourced from the Original Equipment manufacturers.
Our lead sets are designed to equal or exceed the design of the original lead set without compromising on fit or function.

Ignition 7mm Cable data sheet
Our own-brand cable. High spark quality. Lower suppression. Generally used for lead sets which have long runs where conventional suppressed cables are liable to voltage drop. Maglite® core consists of a fibreglass base strengthened with additional aramid fibres, tightly wound with stainless steel resistance wire and covered with a specially developed acrylic conductive coat.

Copper Core Cable 7 mm
Ignition cable with a stranded copper core is used where electromagnetic suppression is not a consideration or where suppression
is controlled by resistive cable connections to the spark plug or distributor / coil.
Copper core cable guarantees the best spark quality with no voltage loss but requires some additional means of suppression
if the Electro Magnetic Pulse (EMP) is to be contained
