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.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors).

Sometimes a bad coil may just be a broken or damaged connector boot. This is especially true on cars with a leaking valve cover gasket where the oil has contamintated the rubber boot and the electrical parts inside. This boot can be replaced on its own without having to buy a whole new coil. This part is also useful if you purchased a coil that did not come with a new boot.

This boot works with the 12131748018 ignition coil only and fits the vehicles listed below.

Sold per boot/per coil.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code, but not always a check engine light. A misfire code may be related to an ignition coil, but could be from other things as well. ometimes, a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.

RACING SPARK PLUG FOR M50/M52/M54 ENGINES
These spark plugs are recommended by BMW Motorsport for use in their DTC racing engines. We find a slight horsepower increase and greatly increased durability over the OEM road car spark plugs in competition use. We attribute the improvements to the fact that these spark plugs are designed for the high temperatures and cylinder pressures encountered in a racing engine. These spark plugs are a direct replacement and come pre-gapped just like the factory road car plugs.
Please note: these plugs are not for the S54 engine in the E46 M3, MZ3, or Z4 M
