B38 X1 — Plugs and Idle Quality
The B38 X1 (sDrive18i) shares the B38's characteristic 3-cylinder idle vibration. Worn spark plugs amplify this vibration noticeably. Replace all 3 plugs at 60,000 km — do not replace one at a time as uneven plug condition causes imbalanced combustion. At 4M Car Care, a full 3-plug B38 replacement on the X1 takes approximately 45 minutes and costs RM 150–280 including OEM iridium plugs.
