How To Change Spark Plugs on BMW X3

Remove the motor/engine cover and foam
- some just lift up
- some are blocked by:
  - intake (flat),
  - air inlet (10mm),
  - MAF pipe
  - air sensor (t30)
  - a loom holder (6mm, t20, or t25)
Should see 4 spark plug thingies (usually on the passenger side)
- pop/lift up the covering clip on the coil pack
- pull the connection plug by squishing side clips
- remove by jerk and twisting the coil pack or use leverage to pull it out
Grab thin wall 14mm 12-point socket (is this also 5/8″?) and swivel or 6-12in wobble extender
- and take out the old spark plugs (x4)
- do this slowly
Compare the old and new spark plugs to see if the gap is the same
- there’s a measuring tool to check between 18,000-28,000? (so this is prolly inches 18-28/1000in)
- or .032mm?
Put the spark plugs back (23Nm or 17ftlb)
Put some di-electric grease at the end of the boot to make it easier to take out (if needed)
Re-assemble everything
