Ignition Leads

The ignition lead (or ‘HT lead’) connects the coil or distributor to your spark plugs. To ensure your engine has the energy to get you to work on time, replace your tired old ignition lead at a low cost with CarParts4Less.co.uk.

The ignition lead carries the 35,000 volts of electricity from the ignition coil to your spark plugs. In most cases, this occurs via the ignition distributor. Each ignition cable features a single wire. A negative terminal on the engine sends the current to ground. The high voltage provides the spark that ignites the fuel-air mixture as part of the combustion process. The ignition lead is therefore crucial to your car’s ability to get you from A to B. Over time, the insulation on ignition leads can wear out. Meanwhile, dirt can also clog the connectors. If you have trouble starting your car, or if it misfires, or if your radio starts to pick up static, then your ignition lead may need replacing. To save money on fuel and ensure your car passes its MOT, you should always replace faulty leads. Browse CarParts4Less.co.uk for the best price on a high-grade ignition lead.
