SOON I will have my XB. Are there any thoughts on the grounding wire kits and the vortex gizmo for the air intake? Noticeable increases in mpg, hp, etc? Thanks from Montana.

I made a homemade grounding kit for my xb and it seemed to help with the alternator wine i was having because of my amps, other than that im not sure if i noticed much of a difference, it cant hurt for the 25 bucks i spent in wire though. Im doubting the vortex thing works at all but ive never tried it
