Best Ignition Coil For BMW N63 FAQ
Q1: What are the main symptoms of a failing ignition coil on the BMW N63 engine?
The most common symptom is an engine misfire, often indicated by flashing or solid Check Engine Light (CEL), especially during hard acceleration or cold startup. You may also notice rough idling, a significant lack of power, poor fuel economy, or a longer-than-normal crank time before the engine fires. These issues often relate directly to degraded ignition system health.
Q2: Should I replace all eight ignition coils at once, or just the one that failed?
For the N63, it is highly recommended to replace all eight coils as a set. Ignition coils tend to degrade at similar rates due to shared operating environments and mileage. Replacing just one coil can lead to uneven performance across cylinders, and you will likely experience failures in the remaining older coils shortly after, leading to repeat labor. Investing in a complete coil pack replacement minimizes long-term downtime.
Q3: How do I know if my N63 requires the UF592 (Bosch) or UF667 (Delphi) coil type?
The N63 engine saw coil design updates over its production run. Generally, older N63 (pre-2012) vehicles used the UF592 Bosch-style coil, while later N63TU (Technical Update) and newer vehicles often utilize the UF667 Delphi design. The most reliable method is to visually inspect the existing coil or cross-reference the original equipment (OE) part number listed on your current coil or in your vehicle’s parts catalog.
Q4: Does upgrading to a high-energy coil require tuning changes?
No, upgrading to a high-energy coil (like the Dinan or ARKAUTO Red Top) does not usually require immediate ECU tuning changes if you are running a stock or mild tune. However, if you are running an aggressive tune, the stronger spark delivered by high-energy coils is highly beneficial as it helps prevent N63 misfire issues caused by high cylinder pressures, allowing you to reliably run higher boost levels.
Q5: How often should I check or replace my N63 ignition coils and spark plugs?
Due to the extreme heat generated by the twin turbos in the N63’s ‘hot-vee’ design, both spark plugs and coils have shorter lifespan than in most conventional engines. It is generally recommended to inspect and potentially replace spark plugs between 30,000 and 45,000 miles. Many N63 owners choose to replace ignition coils every second spark plug change (around 60,000 to 90,000 miles) or immediately upon experiencing the first misfire.
Q6: Can poor ignition coils affect my fuel economy?
Yes. A weak or failing ignition coil cannot properly ignite the air-fuel mixture, resulting in incomplete combustion. This inefficiency causes the engine control unit (ECU) to slightly compensate, and overall engine output drops, leading to poor fuel economy and necessitating increased throttle input to maintain speed. Choosing the right best ignition coil for bmw n63 ensures maximum combustion efficiency.
