[ IMPORTANT SINGLE REPLACEMENT AND BANDING WARNING ]
Electrical Tape Disaster: When the engine warning light comes on, wrapping a cracked or leaking (arcing) old BMW G30 B48 Ignition Coil with electrical tape or silicone and reinstalling it poses a risk of burning the wiring going to the engine control unit (ECU). A faulty coil should not be repaired; it must be replaced with a new one.
Set Disruption Error: There are 4 ignition coils in B48 engines. Replacing only the faulty coil and continuing to use the other 3 old coils creates a timing (milliseconds) and voltage difference between the cylinders. This situation leads to engine vibration at idle and causes the other old coils to fail shortly after. Coils should always be replaced as a SET (4 pieces).
The source of that incredible spark that brings the technology and performance marvel of BMW's 5 Series G30 chassis to life; the A-Quality DELPHI brand imported BMW G30 B48 Ignition Coil is now available! This precision electronic part sends over 30,000 volts of uninterrupted energy to the spark plug, ensuring the perfect explosion of the fuel-air mixture. However, due to excessive heat and years of metal fatigue, it can lose its insulation over time. An old BMW G30 B48 Ignition Coil that is burnt inside and leaking current can cause your vehicle to misfire, lose power, run roughly at idle, and display a "Drivetrain Warning" on the screen. To rescue your luxury G30's engine from this rough operation and prevent the raw fuel from melting the expensive catalytic converter, you can reset your ignition system with this brand new BMW G30 B48 Ignition Coil engineered by DELPHI, an OEM supplier in automotive electronics. This product fits perfectly onto the cylinder head with its original socket and insulated rubber body, restoring that silky and uninterrupted acceleration the moment you touch the gas.
DELPHI Original (OEM) Production Quality With resistance values that the engine control units (ECUs) are looking for, DELPHI quality works 100% in sync with the vehicle's brain and permanently extinguishes the warning light.
Maximum Combustion and Fuel Savings A brand new BMW G30 B48 Ignition Coil set ensures that the fuel in the cylinder burns completely without being wasted, increasing engine performance and reducing fuel consumption.
High Heat Resistant Body Insulation To withstand the high turbo temperatures of the B48 engine, the coil body is armored with special epoxy and silicone components that do not leak electricity (spark) to the outside.

Frequently Asked Questions (FAQ)
When connected to the computer, only a misfire is seen in cylinder 2. If I buy only 1 BMW G30 B48 Ignition Coil instead of 4, will the problem be solved? Your issue will likely be resolved, but this is a short-term fix. All 4 coils in your engine have the same operating hours and the same metal fatigue. If the coil in cylinder 2 has failed, it is only a matter of time before the others fail as well. Additionally, since the resistance of the new coil will differ from that of the old coils, the engine may run slightly rough at idle. For healthy ignition and performance, it is always recommended to replace them as a set (4 pieces).
Do I have to change the spark plugs when changing the coils? If your spark plugs have not been replaced with originals recently (within the last 10,000-15,000 km), the spark plugs must definitely be reset along with the coils. A worn-out spark plug with an increased gap and carbon buildup draws much more current to create a spark than the coil. This causes the brand new coils you installed to overheat and fail again in a short time.
