Thanks pizzaguy, my thought process is do the passenger side first a weekend in the next week or two. Then the following weekend do the driver's side and take my time. I did get OEM from MB for about $40 total, got the hoses from pelican and bolts from needwings. Already changed the plugs last week took me about 3-4 hours taking my time. What i noticed was that the coil pack plugs to the cylinder plugs are numbered so just had to number the coil pack themselves which was first and last coil packs on either side. Did one side at a time.
