Get the Best Priced BMW X5 Ignition Coil

The ignition coil in your luxury crossover SUV is one of the most important parts of the vehicle's ignition system. Without it, battery voltage cannot be increased to the level needed to spark the engine. The spark plugs therefore can't do their job and your ride won't start. Ignition coil replacement isn't the costliest of automotive repairs, so you can get going again without much fanfare. You can, however, save by finding replacements online. Just realize, your BMW X5 isn't going anywhere until the faulty part is replaced.

What an Ignition Coil Does

This induction coil is able to store voltage from the 12-volt battery, until it reaches the thousands of volts required by the spark plugs. Electricity can then jump the spark plug gap so the air/fuel mixture in the engine can be ignited. The coil has an iron core and two wire windings, but the core doesn't form a closed loop. A magnetic field created by the core stores energy when a contact breaker closes. When this opens, energy is released at the proper timing with cylinder pistons.
