Eventuri F95 intake for M50i engine
Hey everyone, i recently purchased the F95 eventuri intake in hopes I could get it to fit. The problem is what I suspected and that is this…once you get the intake assembly planted in the OEM anchor points the unit sits about a half inch too far forward of the turbo inlet tubes coming out of the engine. I’m trying to put a video on YouTube to describe this. The difference is is enough to throw off the smooth flow of air that would (hypothetically) be coming into the engine. The second challenge is that the turbo inlets are smaller than the brackets supplied which means the rubber bellows which attach the intake to the inlet tube won’t sit and seal properly unless you can find smaller ones. I’d say about half inch in diameter smaller than the rubber bellows it came with. Now I can see the subtle differences in how they get 617hp out of the S63 unit.
I had ordered Dinan bellows from their F95 intake in hopes it would be more flexible than the eventuri ones. They are and could technically get the job done despite the misalignment (intake to turbo inlet) if you’re ok with it. However, you’ll have to be also be OK with the rubber bellow sealing points overlapping if you can get it to fit. Another member used the F95 bellows for modifying the Dinan Intake to fit the M50i with this method. |

See pic regarding fitment of rubber bellow below. These are the ones I ordered and as you can see, they are bigger than the turbo inlet and will bunch as you seal it.

Great work.
A thought, maybe F95 turbo inlet will make it work?

I’m going to give it on more shot before I throw in the towel. Thinking I will add / wrap around the turbo inlet lip some material or heat resistance (adhesive backed) insulation to make the lip larger in diameter so that the rubber bellow might fit more smoothly around the turbo inlet lip. Of course, I’d trim this very carefully. |

so the pic you posted here is my engine bay from the looks of it. This was right after i had installed the bellows and had to make do with some bunching until i fixed that issue. What i had noticed is that the passenger side rubber bellow is smaller in diameter than the driver side. I ended up ordering two passenger side bellows and it fits great without any bunching

i wonder if you were to use the airbox mounting bracket for the f95, if the angles would match up better? i'd cross reference the part numbers to see if they're different

I’ve ordered two new rubber bellows (intake hose) with smaller diameters of 3.5 inches on each end. The inlet is slightly larger at about 3.66-3.7 inches. I’d rather stretch the inlet ends of the bellow than have bunching because it is too large again. The sizing of the Dinan is just too far off. One end fits pretty nicely but the other end of the bellow is larger in diameter and is simply too large for either the eventuri intake or turbo inlet if you try and reverse it with fitment.
I’ll have an update on Tuesday after the new hose pieces come in. Last edited by PNWM50I; 10-13-2023 at 06:29 PM.. |

After trying new hoses to connect the inlet tubes to intake unit, I’m unfortunately giving up on trying to make it work. You really can’t readjust the placement of the intake until because it will throw everything else off like the placement and fitment of the rest of the unit. I wish IND had just been straight instead of using word salad to describe the fitment challenge. Bottom line, due to the angle of the turbo inlets, the unit won’t align properly with its design. Bummer!

Looks like I am going to try DINAN since I know this can be fitted. |

mmm Im not a fan on this Dinan intake. How big its and how the cold air has to go through the top of the turbos where is the engine hottest part, is a big no no. OEM and Eventuri gets the air through the sides. I mean it could be minimal impact but not paying that money to find out.lol

I’ve ordered the Dinan and it should arrive next week. It’s not cheap but it’s gorgeous and will improve performance no matter how minimal it might be. Based on the KIES Motorsport youtube video, a whoosh sound should be audible. I’ve wanted an exhaust or intake for the longest time and decided intake won’t take more $$ to get custom fitted va an exhaust system for an F95.
One last pic to show how far off eventuri was. |

Good suggestion. The intake unit needed to sit further back to better align. However, this is not possible because the intake housing cannot move further back due to the strut bar. I tried to align it better but could not due to the strut. I think the inlet tubes are slightly more forward on the F95 engine as they exit out of the turbos.

Do you know what mods need to be done for the Dinan on the M50? I have a 2023 and want to add it as well. TIA |

Mine arrives Thursday. The other forum member said he (1) had to trim excess plastic inside the OEM intake housing to make the Dinan filter fit,(2) order an extra rubber “bellow” for better fitment on both turbo inlets (passenger side part #, see parts listed on Dinan website for the F95 intake under technical info), and some bending of the anchor bracket. I’ve already got the extra parts so the only thing nervous about is adjusting the anchor bracket which holds the intake unit in place. I’ve looked up the same bracket part for the F95 but it’s the same part for the M50i so that won’t fix any issues.

Yes, that makes sense in theory. However, even if I were to purchase the F95 intake assembly (roughly another $1k) from the dealer or online I might still run into the issue of the Dinan intake outlet not aligning with the M50i turbo inlets. It is possible that it could be more offline than using the M50I intake because both the Dinan cover + F95 intake box are setup for the F95 turbo inlet location.
Will see what I can do without ordering the assembly. |
