Customer Reviews
I was after a diffuser that was not too aggressive and still almost looked like it came rolling out of the Audi factory with that diffuser. This CT Carbon Diffuser was exactly what I was looking for!
Absolutely love the new look with this diffuser!
Fitment overall was quite straight forward. The middle clips can be a little tricky to clip in, I had to get a 2nd pair of hands to help out with.
Really happy with the quality!
Install is simple. Remove 2 screws under the diffuser and then gently pull off the old one one clip at a time. Realign the new diffuser and gently place into place. I noted it helps the clips pop in to push from the inside of the bumper as you’re pushing the diffuser from the outside. Might take some trial and error as there is some slight movement within the clips to ensure alignment is perfect. Once aligned secure with the screws on the bottom of the car.
Improves looks quite subtly but definitely a difference. Paired with a Maxton lip and black badges the rear end of the car looks great. Good quality for the price and good result for price too. Significantly cheaper than other diffusers and makes a good change.
