Absolutely Amazing Quality and Fitment April 28, 2022

By __DUKE440__

This was my second purchase from RW Carbon. My first purchase was a Carbon Fiber Rear CF Spoiler that I have had on my “20 440i for just about 2 years now. The fitment and quality of this diffuser is like no other! Just purchased my self an EC Front Lip and can’t wait to get that installed as well! I recommend their Carbon Care Package as I use on all of my products to keep them looking just like new!

Nice quality piece March 17, 2015

By Matt

Purchased this diffuser for my 2015 435i. Diffuser arrived in well packaged box free of damage. Quality and carbon fiber weave is very nice. Installation I did have to remove the rear bumper which was kind of a pain since I had never done it before. Final product is awesome though!
