Spark Plug - Bosch ZR-5-TPP-330 (8165)
Part Number: 12 12 0 040 581
Refresh your 4.4L BMW N63 engine with a set of OEM Bosch spark plugs. Over time, spark plugs wear down and may cause the following symptoms:
- Rough Idle
- Cold Start Issues
- Power Loss/Less Responsive
BMW engines, especially twin turbo variants like the N63, are known to burn through spark plugs quickly. On a stock N63 we recommend replacing the spark plugs roughly every 50,000 miles. However, modified N63's may require new spark plugs as often as 20,000 miles. Ensure your BMW N63 is running at its best with these OEM spark plugs.
