Anyone installed MST inlet on N55 EWG??????
Hey all,
Just like the title says, has anyone with an EWG 435 preferably installed an MST Inlet pipe??? Was having an absolute fit trying to get the silicon body into the space. Got to a point of no return where I could have jammed it passed the oil lines but it didnt seem right and I eased it back out and reinstalled the factory inlet. Watching the Kies video it is not possible to just slide it in like he does so that makes me believe there is something different between EWG and PWG engine bays by the fan. I really want to install and use this piece but would love to hear some positivity from someone who has done it or seen some benefit from it. In theory this has potential to yield some nice MAF gains. Thanks Chase |

Good luck on this - I assume you got the hybrid model?

If you mean the hybrid turbo metal piece, yes, he did. (but his car is not a active hybrid).
and the issue isnt with the metal piece, its with the silicone piece, which is the same regardless of which metal inlet piece you get. Also for reference i have a 2015 335i RWD 8AT and it looked like the same lines were going to be in the way if i were to try to install, so i dont think its a 435 GC thing (like the issue he had with pure inlet). |

@ozymandias435!
I would return the MST and give this a shot. I didn’t even know it existed, I thought it was a E series part. |

Would also like to see a better photo of the inside from the bottom to see how the transition of the ID from the black part to the silver part is. Just because it is 3'' all the way doesn't really help if there is just a big lip right there as the ID decreases down to the size of the silver part. |

Does it have a flange for the turbo bolt? Looks like a great option though! |

Looked straight through to me, that's sort of the whole point. To remove that lip restriction on the factory part. I'll ask them if they have any photos of that to share.

That would be much appreciated! I sent them an email as well asking about the turbo flange for the bolt/nut but yes any more info/pics about the size of the turbo opening would be awesome. Love the metal inlets......make the turbo sound amazing under hard throttle. Just finished installing the MST.....it is a major tight squeeze to say the least.

I assume it comes with Orings? Grooves appear to be shown but not mentioned at all or shown in pics (for turbo inlet side). Need measurement of ID of silver metal piece at turbo side. Need measurement of ID of black piece at top side (assuming its same all the way through as claimed, just need top side). Need photo or description of the transition from black to silver metal part on the inside - is it just an abrupt step down in ID between the two above? Also, it looks like, from the bigger picture down the page, that the silver metal piece is just at the very end of the inlet pipe - not nearly as long as others like MST and VRSF for example. That could be a benefit. Also curious how the silver metal part is attached to the black metal part. Doesnt really look welded, or maybe its welded and pained over, not sure. Need to confirm there is no flange for turbo bolt, although it seems obvious there is not from the pictures. Edit: the other potential drawback i would mention compared to say MST, is that this is black and metal, and located right by the turbo and manifold. Its going to get quite hot and transfer heat to intake air. |

BMS will be here sometime this week. We will have then tested every inlet option for the N55
Basic info on the BMS from speaking to them: -No turbo bolt flange so they could "maximize inlet pipe diameter" -Comes with 2 O rings same as Pure and MST -Comes with silicon coupler for intake connection and 2 clamps Looks to be a great option on paper if fitment is not an issue. |

awesome! thank you for doing the testing! Saw the other inlet thread and concluded on possibly the MST V2 for my 2014 EWG car. However, after seeing your fitment issues above and now this BMS inlet getting released, I want to wait a bit longer for results.

Thank you, are you guys planning to compile all the inlets and compare logs? Really interested in your findings.

It's going to come down to whether he wants to pull the MST to give the BMS a shot because the MST really looks like the best option (based on all tested so far) and based on size/shape/etc it doesnt seem like there's any way the BMS can be better. Will keep this thread and the main aftermarket inlet one updated though. I think he was planning to check that out today after work. |

I don't believe I updated this thread but after I got the MST fully installed all of the fitment issues went away. It takes some work to get it in do not get me wrong....but once you get it in there it settles in and fits nicely. Also have noticed vast improvement in throttle response and the car just feels like it breathes better and takes in more air. On top of that my WGDC is lower at almost every value in my logs. At the top of the 4th gear pull the WGDC is 2% lower (91% down to 89% at 6100 RPMS). Less work on the turbo Ok now back to the BMS, these are my concerns: - No flange to bolt it to the turbo. Only held in by the 2 O rings. I would lose sleep over this. - Connects to the intake by a coupler.....they butt up to one other. Stock and MST both are larger at the top and allow the intake to sit inside them. This is better for airflow. -BMS has a pronounced stepdown or change in internal diameter as the air flows down it and into opening before the turbo. MST has a gentle taper design down with virtually no lip. Again better for air flow. -BMS has the larger CCV connection that will most likely cause the rubbing against the Aux coolant pump. Had this same problem with the Pure Turbo Inlet. The BMS is a quality built piece no doubt but the MST V2 takes the cake of all the inlets tested! If anyone has any questions about any of this or any inlet in general I would be happy to answer them. Again I have personally owned all of them and have used 3/4 available for our cars. |
