Sometimes known as high-tension (HT) leads or Spark Plug Wires, Ignition leads carry an electrical current from the ignition coil into the spark plugs, ultimately, lighting the fuel and air within the combustion chamber of the engine.

SMP Europe’s range of Original Fit Ignition Leadsets contain over 875 references making it the most comprehensive range of OE fit sets available. Our portfolio can be purchased across all of our primary brands,

Intermotor, Lucas, High Volt and Electrospark. We are constantly monitoring the aftermarket to update our offerings to ensure our customers remain up to date and have the sets they need for every repair.

Designed and developed in the UK at our Nottingham Centre of Engineering Excellence, the majority of sets are manufactured using 7mm or 8mm full silicone and copper core cable, however the range also includes 5mm cable O.E sets to cover the Japanese and Korean vehicle parc.

Double silicone cable is used for maximum radio suppression, resistance to temperature, water and oil degradation and chemical attack. All terminals are machine crimped to ensure strong and reliable connections. All spark plug boots and terminal covers are moulded from silicone to give a water tight seal.

The product is extensively tested. These tests include "pull off" tests, both hot and cold, to check that all terminals and connections are satisfactory and a hi-voltage saline solution immersion test to check for current seepage.
