Hello Jay,
You ask why it took so long?
Lemme tell you. I have only driven this X5 for about a week.
During that week, I had a trifecta. Since January I have had it parked.
While removing the ABS module, I noticed the headlights looked dull.
While refinishing the headlights, I noticed old coolant lines.
While replacing old coolant lines, I noticed ugly valve covers.
While replacing valve covers, I noticed 2 non factory ignition coils.
While replacing ignition coils, I noticed incorrect spark plugs.......

You see where this is going?
