I've been playing with my FX and looking into all the great gadgets and accessories....Just added the iPod input with text. Anyway, I was curious if anyone could really tell me the MPG results of adding the cold air systems such as from Stillen? Or possibly the lightweight pulley sets? I'd like to add them merely to add the extra HP when needed. However, I am really curious of the MPG results when driven normally with these ad-ons? I would imagine that it's got to be better by letting the engine breathe better along with the lighter flywheel.

While I'm at it, does anyone know of any other helpful HP or MPG gadgets to add on that really work on the FX?

Thanks much, Robert

Lots of money for no discernible gain, sometimes just an impairment.

Best performance mod is to get an FX45 or FX50.
