**N63TU engines may opt for any ignition coil. We recommend sticking to the Bosch option as it is much cheaper.

Refresh your BMW N63 engine with a set of OEM ignition coils. We recommend replacing ignition coils on a stock N63 every 50,000-70,000 miles. Modded N63's may require new ignition coils as often as every 30,000-40,000 miles. Symptoms of old, worn N63 ingition coils include:

• Rough Idle
• Misfires
• Power Loss

The above symptoms are not always indicative of an ignition coil issue, however we still advise replacing every 70,000 miles on the higher end. Modded N63 engines, running higher than stock boost, put additional stress on ignition components. As such, replacement intervals on modded N63's decrease to 30,000-40,000 miles.
