The ignition coil plays a crucial role in getting your car started and running the engine smoothly once you're on the road.

The distributor – including the rotor arm and a distributor cap which covers it – is one of the many parts in the ignition system. So, naturally, you'll experience all kinds of problems when something is wrong with it – in fact, your car may not start at all.

The fuel filter performs the crucial job of preventing any pollutants from getting inside the engine, keeping your vehicle running smoothly and ensuring optimum fuel efficiency. However, it can only do this if it's kept in good condition
