That's my video I made about the Renntech box that came with my 210. Here are some photos for those that are interested.
The lower portion of the airbox is 100% identical to stock. This is where the air comes from the outside. All baffling is intact. The only difference is the upper "carbon fiber" portion of the airbox. I was very skeptical at first, but it does hold more volume of air.
Stock airbox with baffling, notice the grill on the inlet to the throttle body, this is absent on the renntech box.
Renntech box, same lower section, unique upper section. The Renntech box will come with BMC high flow air filters that allow for more dirt into your engine for all the extra premature wearing performance! They also trap a lot of dirt and the only proper way to clean them is placing them in a dumpster.
Completely hollow inside.
No grill for the part that feeds air into the MAF and throttle body
Stock
I drove quiet a few miles with the Renntech box with the BMC filters, I swapped those out for the vastly superior hengst OEM filters. I did not feel a difference in power. This led to me swapping a stock airbox on and surprisingly the car felt different. Throttle response was not as sharp, and there was a slight decrease in induction noise. I was extremely skeptical of their claims and still doubt their claimed numbers, but it did feel different. The air inlet side of the airbox is the same. I have no dyno results to share, just how the car felt driving when I swapped airboxes back to back.
I did post some photos and video to my Instagram and Renntech responded.
If you use these air filters then I feel sorry for your engine.
Hartmut's wife did not like my comments.
It does look pretty cool though
