COILS TSB

Just as a FWIW, the latest coil part number last two digits have been updated from "09" to "20". My dealer just replaced all 8 of my coils with the new "20" coils and stated that the coils are warranted up to 100K miles. My vehicle is not under any sort of warranty, but since my engine had two separate coil fault codes (i.e. two bad coils with CEL activated), I welcomed the replacements at no cost to me.

Does anyone know if this new revision of the coils actually improves the coil design. My 04 cayenne turbo is tunned and I get some slight timing pulls under WOT and wonder if this change is a significant improvement, that I would benefit from changing the coils.

i don't have any existing warranty on the car: 06 CTT-S with about 51k miles on it.
