I sell the one for the 3.0L Duratec. Here's what it looks like:
It's an 8lber. Not sure what the weight is on the 2.5L one. 8lbs is a HUGE difference over the stock one on the Mazda6 which is 25lbs.
There's also a 15lb one available for the 3.0L (we custom machine it) that is just a lightened version of the stock one that's quite a bit more streetable than the 8lb Fidanza. I doubt anyone with a Noble is really too worried about streetability though
