E86 M S54 with Eventuri and sound generator!

I wonder if it has any effect on the air/fuel mix since it spurs off after the MAF. Does the engine idle and run as normal with it fitted?

There is a membrane in the large bit connecting the two tubes which allows vibrations to transmit but no net air flow

Yes, there is a membrane, an eardrum as such so no airflow issues. All is exactly as before in regards to cold start, idle, performance, except a better in cabin sound between 4k and 6.5k rpm…

That makes sense, so that it conducts sound without any communication between the intake manifold and cabin.

Hey Mate!

Cheers,

Thanks. It looks interesting. I wonder if it has any effect on the air/fuel mix since it spurs off after the MAF. Does the engine idle and run as normal with it fitted?

Recently, I changed my aFe intake to a GruppeM because the powder coating on the heat shields was breaking down allowing them to rust. The GruppeM looks much better, but the sound from the aFe was louder and much more aggressive. Ironically, it sounded closer to a full carbon airbox whilst the GruppeM sounds closer to the stock airbox (as best as I can recall from a decade ago). I’d like to hear more intake sound as it’s a little tame now so I’ll try this too.
I’ll PM you for his details

PM Replied to Richard!

Thanks Sal
