The M Performance one looks identical and does have slightly better figment (I had one on my M4). But with the M6 diffuser from BMW being three times as much as RW Carbon, it was a no brainer. While I prefer to buy OEM, something as simple as a diffuser doesn't make a big difference to me if it is aftermarket.

Install was slightly longer than anticipated to get the best figment. I was expecting a 15 minute install, but it ended taking about half an hour. Not bad though. It probably didn't help that I did it without any jacks and in the middle of a February winter!

Thank you
