Do they have inlets?
Yes they do…..per straight off their website specs….
"We have also managed to increase the inlet tube cross-sectional area by over 30% compared to the stock intake as it feeds through the openings in the strut braces. This allows the turbos to work more with less restriction and reduce the waste-gate duty cycles." 👍🏼

We're you asking if Eventuri has turbo inlets similar to Dinan? If that was the question they do not unless they were released in the past week. I just sold my Eventuris for that reason. I really liked them but decided to try something new.

love my Eventuri's. Wouldn't go through the effort to sell for dinan turbo inlets/intake. Especially with their major supply issues across their product line. Gain is negligible at best regardless of what is claimed similar to the turbo intercoolers people have bought and found out the hard way that its next to a useless mod. Intake gain is negligible as it is.

with that said, if DINAN existed when i was in the market for the intake i would have gone that route for a full set up over eventuri and the added carbon bits. Price point is very similar.

wish the inlets could be fit to the eventuri but they designed them to be installed as a stand alone option to the factory filter boxes which the eventuri replaces.

They must have a secret stash since they claim to be out of stock.

Timing was just right is all. Monthly batch of carbon came in the same day he submitted the ticket. Shipped what we could on the 10th and now we are back to backorder til the next batch of carbon. BO is only 3 units now though so thats a win in my book given history of the part.

Mine are cracking and the dealer told me I am getting a crankcase ventilation error code. Not sure on the exact code. Has anyone else had a crankcase ventilation code because of cracking of the inlets?

I thought it was just the clear coat cracking. Not cracking all the way through the carbon...

Received my replacements. No holes visible with flashlight and no error codes driving around after installation. CS was fantastic, likely top 3 so I wouldn't hesitate to give them my business going forward.

They look great. Fingers crossed for no cracking down the road.

It is just the clear, but I am getting a CEL and my dealer replaced a couple items that could potentially be causing the problem. Seems like the only thing it could now be is the cracked inlets. It doesn’t seem to me that cracking in the resin and not the CF would cause a CEL but I have no idea.

Were you getting an error code before with the cracked inlets?

No. I purchased during Black Friday sale, just got my car that week so I was waiting for my 1200mi break in. Saw the post about the holes and checked before installing and they had several holes.

New to the forum, just picked up my 22 M5 last week.

Got the Dinan turbo inlets in today, but one looks off. Thoughts? Did yours look like this?

That is the other end from where the issues likely occur.
