I am selling a used Cortex Tuner (unlocked) and RotoFab cold air intake for a G8. The Cortex is the GM version (#2950) and will work with the G8 or other GM vehicles. It is currently loaded with the G8 RotoFab CAI performance tunes from Superchips. Other tunes can be downloaded from the Superchips website for something like $3 each. The RotoFab was used for about 8K miles, but might as well be brand new. The filter is the upgraded aFe dry style, and does not need to be oiled. Both the tuner and CAI include all original parts and paperwork/manuals.
Superchips Cortex: $260 (plus shipping) - SOLD
Rotofab: $260 (plus shipping) - SOLD
I will also take $500 for both, as this makes a great combo on the G8!
