S54 Intake Sound Question/Debate

[liam821]

Another option, you could do something like these sound makers. Cost me $50 for another stock airbox to pull the trumpets out (or free if you want to hack up your stock box), $125 in ITG filters, and $20 for a CSL IAT, oh and some sort of oil catch can for the PVC. Running a modified CSL tune I did myself, car runs awesome.

With that said, using a CSL airbox is really the better solution, you get that cold air and it makes dealing with the PVC system easy. I don't really care for max power, I just wanted more sound, so this is perfect.

P.S. This passes smog (DEQ) here where I live in Oregon.

This may not help answering your question but I took mine off to sell, but I now missed it so much that will put it back on. If you listen to how the GT4 RS sounds, it gets you an idea how it is.

mine is a Z4M

Wow. Thanks for the feedback. I messaged the creator to see if he had E46 install instructions.

Has anyone installed that Z4 M sound generator in their E46?

Keep in mind this will pass smog computer check, but will fail visual. Needs to have a CARB EO number to pass visual test.

Right. Where I am there is no visual, just obd2 plug in, so it’s what I go off. I understand you guys in California have it a bit tougher. Oof!

[Notan_S54]

Think this is the one referred to.

Correct. Here is IND distribution listing. I think they are karbonius sole distributor in the US now.

Oh, and if you are worried about smog, karbonius now makes an oem carbon intake that produces the sound and uses the maf; so that may pass California inspections if it’s just the plug in test.

Do you have a link to this new intake?

Does the gruppe M intake have any sound benefit? Seems like it should be similar to the eventuri except it has a snorkel to the front kidneys

GruppeM is louder than stock but not as loud as Eventuri (which is an open filter inside engine bay). GruppeM a better design power wise. But the thread is about more intake sound so not the design you’re after.

This was what I was looking for! After having the Karb CSL box on my car it was time to move to a setup that didn’t require removing every two years. Good to know the eventuri + oem style setup still makes ~80% of the noise

This was my path, Karb CSL to Karb OE + Eventuri. I do not regret it but I sometimes miss the deep growl from the CSL intake. Power wise is the same, and drivability is same as factory.

[Notan_S54]

Is better than stock plus Eventuri for sure, but I would say is not as loud, perhaps 80% of the volume. The sound is also a bit different as is higher in pitch and not as gutural as the CSL.

i have the two setups, what you posted above and an actual CSL Karb.

It’s a visual inspection too. Some places might turn a blind eye but a big ass carbon fiber intake manifold is really asking for it lol.

Yeah I can’t imagine the intake being mistaken for oem on our cars lol

It’s rough being a car enthusiast and wanting these sought after mods haha!

Has anyone tried this? I would be curious as to the sound comparison to a CSL. It claims most of that without the tuning headaches.

Looks like the greedy pricks at IND raised the price a few hundred bucks on this combo kit.
