Ignition leads connect a vehicles distributor to the spark plugs. They play a vital role in the timing for the ignition. Therefore the ordering of the leads is vital. Ignition leads are often known as HT leads, which stand for high tension leads. The type of lead required for your vehicle varies according to the vehicle. Be sure to check this before purchasing. Over time Ignition leads begin to wear, whilst the connections become loose as well as the lead itself becoming perished. A faulty lead can potentially cause a misfire, which in turn could cause an increase in fuel consumption and even lack of performance.
