Good luck- I have never heard of black coils on a VX. I have a Trooper and VX so Ill try to find any different #'s or codes on block or firewall at home this evening. They are not covers on the coils either. They are "housings". I guess you could swap internal components- but time and labor wouldnt be worth it so I doubt it very seriously. People have lost their engine as early as 5,000 miles so it may swapped. Where did you buy it? You might be getting into legalities if you bought it from a dealership or something.

Your build # is higher than mine so it cant be a mid model change.scratch one theory.

I had an interesting oil change yesterday on both. same wrench, same filter, same oil capacity, 2 mobil 1 5 quart containers.needless to say it went pretty darn fast!
