Ignition for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

Your BMW's ignition system is critical for smooth engine operation. This category contains parts used in the BMW ignition system, including spark plugs, ignition coils, spark plug wires and boots, ignition rotors and caps, distributors and distributor caps. On most 1991 and later model BMWs, your car has what's known as a coil-on-plug system, where each cylinder has its own ignition coil that sits directly atop the spark plug (so you won't have spark plug wires on those BMWs.) A fresh set of spark plugs is an essential part of any BMW engine tune up.

A simple yet effective upgrade, these Bav Auto High-Performance Ignition Coils feature modified core windings that offer increased firepower and promote a faster, more efficient burn. The result is greater low-end torque and increased horsepower in the mid to top-end. When used in a properly functioning engine, a noticeable difference can be felt. In addition to better torque and horsepower, fuel economy is also improved! These coils come with new spark plug boots. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability.
