Ignition for BMW 3 Series E30 (1984-1991)

Clear BMW chassis

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.

Loosen the reins on your thoroughbred with our 8 mm ignition wires. Stock Ignition wires have built-in resistors that reduce voltage to your spark plugs. That's like keeping a tight rein on a thoroughbred race horse -- it wants to run faster but can't. Our 8mm wires loosen those reins, providing the hotter spark your BMW craves. Both the wires and boots use a spiral core magnetic suppression conductor to provide a higher spark voltage for maximum combustion efficiency. And they're insulated with 8mm of pure silicone to completely eliminate interference. Be aware that due to the increased size of the wire these will not fit in the factory wiring loom. 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. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.
