Carbon Fiber Air Box Installed - Pics

Post by slownrusty »

Carbon Fiber Air Box installed. Bought out of Germany, 6-8-week build time, these built to order.
Purchased from:
https://www.vft-opitz.de/
Point of contact: Christian Opitz (good and attentive communication)

Tricky fit - took quite a few hours especially as I did not want to scratch the new CF airbox. I had to remove the engine mounts and jack up the engine under the oil pan, then tilt the engine to the right to provide just enough space to remove the factory aluminum box and squeeze in the new CF box, as it is quite a bit bigger than stock. Also required a small modification to the throttle cable bracket and trimming one of the coolant lines. Also requires a cone filter (I used K&N) RU-2430 and made two aluminum brackets to support the AFM. The factory air filter box will not work with this CF box.

Benefits: 13lb weight saving and more airflow to cylinders 5 and 6. I took the car for a 10-mile blast after the installation, and it drove great.

That's pretty cool. How's it sound? I think I remember hearing the e46 csl sounded better due to its cf airbox.

I wonder if you could coat it in something so you didn't have to worry about getting it in and out every time.
Did you provide the dimensions? I'd be pretty interested in one of these depending on price and if I could get one that didn't require me to use a different airbox.

I'd be curious on the price too if you're willing to share.

Hi,

I am from the very first US people who ordered this box,
It was around 7-10years ago form Christian. Quality has
been improved by a lot since back then. We recently ordered
another one for E28M5 with the package I offer, cams standalone
etc

The major benefits from this box is reducing weight from the E28
nose as every pound is important...also it does not get as hot as the
aluminum/OEM.

Its a win win choice. I wish it was made from real Carbon-Fibre
as the ones for S54 CSL which I have installed many on E46s. Its
going to be even lighter than the current version from FRP

Hmmm let me talk to Christian to see how feels on this subject..

Pics bellow.

Regards,
Anri
