    Eventuri Hybrid Airbox

    Ya all see this? What do we know? Will it be produced? When and for how much? I'm stoked another CF airbox option is (potentially) available.

Used in conjunction with our Eventuri intake for the S54, our Hybrid airbox brings the functionality of running an OE plenum while having the sound of a carbon airbox! Gone are the headaches of tuning, making IAT looms, relocating dipsticks and running into drivability issues because we have designed this airbox as a true plug and play solution. It fits like stock, uses the OEM MAF and even has a bracket for the dipstick. But wait, there’s more! We’re so excited about this new airbox that we want you to try it out for yourself and provide feedback before the release! So, if you own an E46 M3 and you’re based in the UK, comment “TEST DRIVE” below for the chance to come drive this exact car and experience the hybrid airbox goodness for yourself! #bmw #bmwm3 #bmwlove #bmwgram #bmwrepost #bmwclub #bmwnation #bmwe46 #e46 #e46m3 #e46fanatics #e46gang #e46bmwnation #ultimateklasse #e46vatto #ultimatedrivingmachine #csl #m3csl #bmwm3e46 #e46er".

    Is that their solution for not being able to properly tune a csl airbox??

      Hopefully there are exterior and in-cabin comparisons with a traditional CSL airbox coming soon.

        I could see how this would be great for all your people in the nanny state of California.

          This a cool development. I don't think this would help more with CARB compliance unless they get an EO number but the design and ability to run a MAF is interesting. TBD if it makes a substantial difference in power vs the traditional CSL style boxes.

            Isn't this the same as Karbonius' CF MAF airbox?

              The Karb box is OE form factor. This has an integrated MAF location and no need for an elbow.

                I haven't been keeping up with CA smog laws, would that box fail visual? Really it's super similar to OEM just out of carbon, using the stock MAF and DME tune. I'd think you wouldn't have a problem smogging this.

                  This will fail the visual side, but will pass the ODB test. This is a product i would definitely be interested in. I wouldn't want to deal with having to have 2 DME's or flash the DME every 2 years for smog.

                        Yes and would like to hear difference between existing Eventuri intake vs new hybrid unit. Is the difference in sound worth the extra loot. This assumes they will continue to sell the existing part.

                            If the sound in the clip is accurate, the hybrid unit sounds great (both in-cabin and outside) and very similar to a traditional CSL box without the headache of MAP, tune, etc. Looking forward to pricing.

                              The sound clips in the IG video sound great. Just want to know how accurate it is. I have the Karb MAF airbox with Eventuri and it definitely doesn't sound as loud or has as much of that deep warble sound like this new eventuri box.
