The one that was factory on my 126 was an egg crate type thing with little squares cut out in it. I ordered one from Performance Products and when I got it I wasn't happy with it because it looked totally different and was thinner and I sent it back. Then I went to the MB dealer and ordered the MB PART (woo hoo) and it looked identical to the Performance Products one except that it had a silver heat shield insert in one area. I was wanting what I had on there, but I figured that since MB sold this one now it was improved and all and I kept it.
