MPPK intake vs. Dinan cold air intake

BMWApp · 09-05-2021, 12:30 PM

I have a 2015 435i with the MPPK. I have tuned the car but am still running the MPPK intake with a drop-in filter. I am interested in running the Dinan cold air intake instead but wanted to see if anyone has made this change. Or, has anyone upgraded to the Dinan cold air intake from the stock intake? If so, what are your thoughts?

Skip the dinan, stick with the mppk.

If you switch to the Dinan be sure to install the supplied MPPK airbox blocking plate. (Eliminates the red portal opening in the MPPK airbox bottom). The Dinan is designed to be a resonant closed-airbox cold air intake, and won’t provide any advantage otherwise.

Is that because the Dinan cold air intake isn't an improvement over the MPPK intake or do you say that for some other reason?

Makes sense. My issue is that I don't have the blocking plate since I am not the original owner and didn't install the MPPK.

don't do it man. the Dinan is k own to have weird issues sometimes and maf reading problems.

the mppk is a better choice and makes more power than the dinan.

Thanks. I have read a few things about the Dinan cold air intake but had one on my 340 that I liked so I wanted to get opinions on theirs for the N55.

Stick with the M Performance Intake and a drop in filter from aFe or K&N. The Dinan intake looks pretty but they screwed around internally so it doesn't match the environment expected by the MAF sensor, so it can give crazy readings.

There's a thread all about intakes that a couple guys did that documents this.

Thanks. I do have the K&N filter and like it. Sounds like I should stick with my current setup based on your feedback and everyone else's. I'm fine with that, as I do like the sound and throttle response.

My own experience is only with the Dinan vs. the stock (non-MPPK) intake/filter. Where my stock airbox bottom has with the built-in simple thermo-regulated ‘cold pkg’ heated-air intake port in the airbox. I don’t have MPPK. I was attracted to the Dinan because it’s a sealed, larger volume box mated with a smoother, more consistent larger diameter cross-section intake tube. With the low O2 up here at altitude, optimizing what little I got has always proved fruitful.

I only did some early-on intake testing using PerfExpert, and my timed-section backroad drives back before I had MHD. (and I haven’t had any motivation since to switch back to repeat my testing). I tested 4 configs (I’m an aero engineer geek): stock with port open and port closed, and the Dinan with port open and port sealed. I was trying to see what the effect was of the stock port, but also to try to see if I really needed to seal up the airbox ports as Dinan instructed (potentially affecting my cold starts). I also knew MPPK had the big added port, so I was looking to see if opening the ‘cold’ port might have a similar (though smaller) effect.

My takeaways were:

Performance (peak power and responsiveness)
Dinan sealed port
Stock closed port
Stock open port
Dinan open port

Intake roar (from drivers seat, windows down)
Dinan open port
Stock open port
Dinan sealed port
Stock closed port

Thus it’s my advice that if you’re going to run the Dinan, run it sealed. I felt it aided responsiveness and enhanced the top end (a bit more breath at higher revs). They didn’t design and include 2 different port-seal kits with the intake to save money. And if you already spent for the MPPK box, it makes it no advantage over the stock airbox bottom, as you’d seal both.

Note, I’m aware of the intake and Dinan MAF issue threads here, which I think are good info but incomplete, never running the Dinan as a fully closed airbox as the intake was engineered - and only using it unsealed with an MPPK open-port airbox bottom… And I agree that an improvement on stock is a better flowing drop-in filter. I just don’t think opening the airbox adds anything but sound.

Was away a few days and didnt see this until now, surprised no one linked my thread...

I studied this in depth, OP read my thread: https://f30.bimmerpost.com/forums/sh....php?t=1765289

I would not waste money on the dinan or any other intake for that matter, unless you are seeking only a sound change and no performance. If you want to improve the "intake system" get a turbo inlet like MST v2 and retain stock intake. BMWApp

Thank you for your reply and the link to your thread. You did a great job with the research and write up. I appreciate all of the info! It helped a lot.

The MMPK box is superior to the Dinan and stock airbox, so it’s worth it if you can find one.

I have MPPK. Replaced intake pipe and upper box with BMS intake. No perceptible performance difference other than a now-drifty idle on a cold start, and I found the turbo noise intrusive to my surprise — thought I'd like that! — so I'm probably gonna yank the BMS and go back to the MPPK box.

Yup - a common experience for those who install instakes. No performance increase, potential drawbacks, and a sound that gets old quickly

I did appreciate your thorough analysis about intakes but much of it was over my head, and I didn't see the link to it until after I'd ordered it.

An objective FAQ/wiki "sticky" about performance upgrades especially re cost/benefit would be useful to those of us without access to test equipment, or just getting started. Might reduce the number of "which intercooler should I get?" types of posts.

Anyone want to buy a slightly-used red-filter F30 N55 BMS intake? 😉

I thought about making such a thread (and IIRC someone PM'd me about it to get a draft started) but haven't had the time necessary to dedicate to making it as good as it would need to be. If someone wants to take a crack at it I would be happy to add/collaborate.

1. BMS is the best

2. just put a jb4 on it

3. add 6 gallons of e85

4. Dinan is the best value per dollar per hp you can buy

5. always gap your plugs .020-.022

6. straight pipe and resonator removal is the best exhaust setup with no rasp

7. if you want customer service VRSF is your best bet

8. Vargas is the best turbo for everyone and you get awesome customer service

9. just unplug the maf

10. ghassan automotive is the best for engines

and finally

11. lpfp is a must if you mod your car.

hope that helps buddy

I've said elsewhere - there was a noticeable difference going from the stock box (with drop in filter) to the MPPK box. Less lag, and better sounds.
