Frequently Asked Questions (FAQs)
1. What are the different types of ignition leads?
There are three types of ignition leads: copper core, resistive, and reactive. These types differ based on the materials used for the conductor and the type of resistor required for interference suppression.
2. What do upgraded ignition leads do?
Upgraded ignition leads, also known as high tension leads, connect each spark plug to the distributor or ignition coil. They ensure the transmission of voltage to the spark plugs, preventing intermittent sparks and misfires. These leads have thick outer coatings that are heat resistant and serve as good insulators.
3. Are distributor caps still used?
Most modern cars now use electronically controlled ignition systems and have moved away from traditional distributor ignition systems. However, vehicles produced before the mid-noughties may still use distributor ignition systems.
4. What causes ignition leads to fail?
Ignition leads can fail due to excessive heat and vibration, which can lead to the breakdown of the insulating material and internal coil failure. Worn secondary ignition components, such as spark plugs or wires, can also cause the coil to work harder, requiring more voltage and reducing the operating life of the coil.
5. Are ignition leads universal?
Sparkplug leads are commonly designed to be a direct fit for a specific engine application. However, there are also universal leads available that can be cut to fit different engines, providing more flexibility in installation.
Replacing old spark plugs and wires with new ones can lead to noticeable improvements in performance. The engine will run smoother and faster, and the car will have better acceleration. Additionally, there may be an improvement in fuel economy.
7. How do I increase my ignition power?
To increase ignition power, you can start by upgrading your spark plugs to platinum or iridium. Another option is to upgrade the plug wires. Timing changes can also help improve ignition power.
