This is the 5th video about my new project car, the Seat Leon Cupra 2019 model. In this episode I am installing the aftermarket rear "diffuser" from Rieger and I am also sharing all OBDeleven mods I have applied so far.
From this experience I can tell that this component gives the car a more-aggressive look and I believe there is no such functionality as a "diffuser". Perhaps I should create a custom REAL diffuser, although taking advantage of its capabilities can be done at very high speeds? Let's see...
I have decided to keep showing the Cost of Goods (CoG) in the video description rather than within the video:
RIEGER diffuser -------------------- 210
Extra screws ------------------------- 1.1
OBDEleven Pro --------------------- 150
TOTAL [EUR] ------------------------- 361.1
GRAND TOTAL [EUR] ------------ 983.1

this is the most clear video of defuser replacement on UA-cam, Thanks man
Just fit mine today using this video, brilliant video mate. I agree I hate drilling and using different screw to the oem one.
Ziet er goed uit maat!
Il be watching this video when i wil be instaling mine ... thank u 👍
Thanks a lot for your comment! Good luck and if you need further help, you know where to find me =)
Great video. Audio was a little off for me but easy to understand!
Hi Matthew! Thanks a lot for your comment and for sure I will take this into consideration for the next one! 😉
thanks good info, i'm about to order this diffuser, although you need a bigger exhaust 😀
🙌 Agree! This will be the ideal upgrade for spring time! Stay tuned! 😉
Maybe the Maxton design would be a better fit but a little less aggressive in the looks department compared to the Reiger
Good suggestion! Thanks!
That isnt good for areo because its much lower ?
Hi was geht! Thanks for your question! What I meant to say is that the Rieger diffuser will provide a more aggressive look to the rear end of this car but I doubt it will be of any aerodynamic advantage (I haven’t tested it) as there is a noticeable gap between the rear muffler and the diffuser that can create air-pressure at high speeds. The aim of a rear diffuser is to help escape the air beneath your car, improving the overall downforce (the car sticks to the ground). A rear diffuser usually ends towards the middle of the vehicle and is used in combination with a front splitter/diffuser. The flatter the vehicle’s bottom, the more aerodynamic advantage you will gain. This advantage is noticeable at high speeds, not on a daily drive. Also, lowering the car might help (shorter air-gap between the car and the road, more air-pressure/speed is generated). A few years ago, I helped developing a front/rear diffuser kit for a Caterham (UK MSVR Championship) and that thing was simple and huge! We made it adjustable, so it could be tuned depending on the track. Check out this video (ua-cam.com/video/BrGjDNX8dPA/v-deo.html) from XF Motorsports in which a diffuser kit is developed for an Audi RS3. Hope this helps!

Any new mods?
Hi Giroud. Unfortunately, I have been busy with the next video. I haven't had the time to keep digging in OBDEleven. Next video about the CUPRA soon =)
