Spark Plugs +
Spark Plugs Close
Spark plugs ignite the mixture of fuel and air in the air to power your car's engine. Over time spark plugs deteriorate due to wear and tear and deposit build-up, which can lead to misfiring - or even mean your engine won't start. You should check and change spark plugs regularly to ensure they're performing properly - check out our spark plugs range for a replacement for your car.
Rotor Arms +
Rotor Arms Close
Rotor arms are part of the ignition system, and are designed to spin around inside the distributor cap whilst making contact with each electrical terminal inside. This high voltage then travels via the spark plug leads to the spark plugs for ignition. Unfortunately rotor arms can wear over time, so you'll need to replace them to maintain your engine's performance.
Ignition Modules +
Ignition Modules Close
Located either on the distributor housing, in the distributor itself, or in the engine compartment, ignition modules receive a signal from the magnetic pickup or sensor in the distributor. The ignition module uses this signal to open and close the ground circuit to the ignition coil, firing the spark plugs. If your ignition module isn't behaving then check out our range of replacement ignition modules for your car.
Ignition Leads +
Ignition Leads Close
Ignition leads are pretty important parts of your car's engine ignition system. They connect the distributor to the spark plugs, carrying High Tension Voltage from the ignition coil to the spark plugs. Misfires, high fuel consumption and MOT emission fails can all be signs of faulty ignition leads. Take a look at our ignition leads range to find the right parts for your car.
Ignition Coils +
Ignition Coils Close
An ignition coil is a transformer device, and works by transforming the 12 volts from the battery into the 20 or 30 thousand volts needed to get the spark plugs fired up. Failing to start, misfiring, stalling and backfiring can sometimes be signs of a failing ignition coil - in which case you can get a quality replacement ignition coil from Halfords.
Glow Plugs +
Glow Plugs Close
Although they look similar to spark plugs, glow plugs are instead designed to heat and start diesel engines. When the engine is cold, glow plugs generate heat to warm the engine block, making it safe to start the vehicle. Slow engine starts - or a complete failure to start - are both signs that your glow plugs might need replacing, so take a peek at our glow plugs range to find your replacement plugs.
Without an ignition distributor you won't be going anywhere. An essential link within the engine's electrical system, the distributor routes the high voltage generated in the ignition coil to the spark plugs. If you suspect there might be something up with your car's starting system then you'll need to get it diagnosed, and replace the ignition distributor if it's at fault.
Distributor Caps +
Distributor Caps Close
Part of your car's ignition system, the distributor cap works together with the rotor arm to transfer electrical charge from the ignition coil to the spark plugs. After being subjected to constant electrical charge and sparks, metal terminals inside the distributor cap can become corroded, leading to misfires. If this happens you should check out the Halfords range of distributor caps for a replacement.
A car's ignition condenser is a temporary storage device for electricity, helping reduce spark at contact points as they open in the distributor to reduce burning of the points. If your engine problem has been diagnosed and you need a replacement ignition condenser, then browse our range to find the right component for your car's make and model.
