I tried purchasing one for the 330i from ikon motor sports about 6 months ago. Build quality was absolutely awful, I sent it back immediately. The item was all swirled out, didn't fit properly and had a nice crease down the middle. If your gonna go rear diffuser, do it right and get the m performance

I do not understand why you would want an aftermarket diffuser. Always troubles with proper fitment. Go for OEM!

I bought an "IKON" branded rear diffuser (theyr'e now out of stock) and it fit perfectly. I was surprised but it looks great and does the job. Just my experience...

If you're comfortable with body panel clips then it's not so bad. There's a lot of them but once you start getting one end free you just keep going around. Just gotta be careful not to scratch the rear bumper's paint.

Thanks! So the rear bumper doesn't have to come off at all then?

bought mine from advance tuning on ebay. i really loved the CF but wasn't willing to fork over $1400 for the OEM diffuser for a little carbon fiber.

this one was my fave aftermarket one because it had the most 'fins' on the diffuser, like the OEM CF one just in gloss black.

fitment is on point and no issues at all, not bad for $169

Yeah, I got the same one from IKON with the 4 fins in the middle. I think they all come from the same manufacturer in China. Great fitment for the price!

Nope not at all. Its a bunch of clips and then a few screws below the center part of the diffuser...
