Hello

Can someone show me how to replace my spark plugs:
99 clk320 (275k miles still runs and looks good)

1) Will I be able to do it myself.
2) Do I need any special tools.
3) Does the engine need to be re-programed with the new spark plugs once it's
replaced

Any tips that can help is appreciated.....

Thank you....

1) Will I be able to do it myself. - Yes, if your semi mechanically inclined.
2) Do I need any special tools. - A spark plug boot puller will help you avoid damaging the spark plug boots. However, with 275k you should aalso be replacing the spark plug wires too. Other than that a spark plug socket will be needed. I would also recommend some anti seize paste on the spark plug threads as well as di-electric great on the spark plug tips to allow the boots to engage easily and conduct electricity well.
3) Does the engine need to be re-programed with the new spark plugs once it's replaced? - No

FYI - Dielectric grease is good to use, however it is non-conductive.
