BMW B48 OEM Ignition Coils

Description

Set of (4) OEM Eldor or Bosch Ignition Coils

SKU: 12-13-8-643-360

These Eldor & Bosch ignition coils are direct OEM replacements for all B48 engines.

Ignition coils are responsible for powering the spark plugs, and are critical for proper engine timing and performance. We recommend replacing the ignition coils every time you replace your spark plugs, or every 45,000 miles on stock engines.

Symptoms of bad ignition coils are similar to those of bad spark plugs: poor idling, slow starts, sluggish acceleration, and engine misfires.
