Even if he did make one for a MS3 I wouldn't bother with iraggi. I had one on my civic, it caused alternator whine and didn't put out any more power than the stock one that I could tell, while it worked. It lasted maybe a year before it died completely. His claims are outrageous and the alternators are of low quality, they're just rewound alternators like you'd find on an older, bigger car. The guy at the alternator shop said it might put out 115 amps MAX, it was rated at 185 I think.
