Issues - Spark Plugs

  • Worn spark plugs show wide gap
  • Broken insulator
  • Fouled spark plugs
  • Corroded spark plug threads make it difficult to remove an old plug. Solution is to use high temperature anti-seize grease available from autoparts stores when re-installing new plugs.

Parts - Spark Plugs

  • 2003 Update W220 S500 Chassis Number: 220.175 and Engine Number: 113.960
  • M-B part number is 003-159-66-03-26 which is the same plug as the Bosch F 8 DPP 332 which is no longer available.
  • Bosch equivalent spark plug is FR8DPP33+.
  • Denso equivalent spark plug PK16PRL11. (Denso OE quality resisted platinum spark plug with pre-set gap of 1.1mm.)

Parts - HT Wires

Edit required.

A new plug wire resistance is approximately 2.18K ohms.

Issues - HT Wires

  • Spark HT wires have a limited life.
  • The resistance element in the HT wires often fails or goes high resistance due to fatigue.
  • HT lead insulation can break down causing arcing to ground.
  • A special spark plug wire removal tool is available. It is a 17mm, open ended tool with a 25mm off-set and is made by JTC with part number J-1308. It can be found in eBay for $20.

  • The rubber boot on the HT Wire is difficult to remove from a spark plug even when using the special removal tool. Solution is to apply a small quantity of dielectric grease when re-installing new plugs. This helps keep moisture away and stops corrosion. Makes it infinitely easier to remove HT Wire boot.
  • A regular 5/8" spark plug socket with a rubber insert works well for removing spark plugs. However the secret is to use a variety of extensions eg a short 1" 3/8" drive extension on the tight spots in conjunction with a with swivel head.
