Im about to order the BMW lower air box #11122334344. I got a great price from Brian at Sun Motor Cars. Does anybody know if it uses the same size filter as the stock M235ix or is it different?

What's the benefit of the lower air box versus the stock one?

Yes Brian is DEFINITELY the man. Have met him in person a few times very solid dude.

Saw that this has an open port assume to suck more air in? I have the Dinan CAI and just ordered the AFE air scoop to shove more air in versus pulling more air in from engine bay which I believe is what this does. Should accomplish the same thing.

Yes, same size filter is used. I have it on my M235 and you get a bit more turbo and wastegate noises. It's lovely.

+1. It seems like this community has quite a few vendors who go above and beyond.

OP, can you post up pics when you get it installed.

I'm on the fence about this mod; seems cheaper to just cut a port on the stock airbox to the same dimensions as the MPPK air box. The only thing that would be missing is the porting around the cutout.

Would be interested to see how the results compare to this that I just ordered. $50 figured why not.

Thank you very much !

I wonder if there are any gains to be had from this part paired with the Dinan or stock configuration with drop in. How much did you get the part for?

[XutvJet]

Gains? Unlikely, but like the MPSS exhaust, the gains are in sounding like you're faster. LOL. The only difference with this box compared to stock is that there's an additional cutout which pulls in air from behind the headlight. This is the airbox you get if had a 335 or 435 and added the MPPK "kit". It's also the same lower airbox used in the M2.

we went over this in another thread, the AFE scoop does absolutely nothing.

You also need to dremel a piece off the get it to fit right. It also doesn't bolt up where it says it does since its for another car, so get some gorilla glue and stick it down.

Thanks for the tip. My Dinan guy said it would help with his CAI. Will give it a shot if it doesn't snap right on it's going back. aFE said direct fit no mods necessary.

Just theoretically it seems like it should help.

I had the AFE scoop teamed with MPPK airbox. The scoop fit in no problem. No gluing or anything else needed. What holds it in place is the OEM plastic screen that gets removed to slide in scoop and then the screen is reinstalled which then holds in the scoop. I ran the scoop for a while but never felt any difference and data logs with the Torque app showed no differences in reducing intake temps, timing improvements, etc. I removed the scoop and left off the screen and continue to run the MPPK airbox.

Did you feel or hear any difference with the MPPK airbox?

[bryan_G01]

i wouldn't cut a hole or use a different airbox with a hole in it.
If you had a hood scoop or something, than it would make a little more sense.

Our engine bays get so hot as it is, your just going to be sucking in hot air.

That's my concern with all the "filters on a stick" as well which is why I went w the Dinan CAI. That said I don't know enough about this stuff to say for sure I listen to my mechanic on such things.

I installed the MPPK lower air box in my convertible last month. My car also has the M performance exhaust. There is no difference in 40-80mph acceleration time (the only before and after test I did). With the top down, sport+ engaged and then dynamic stability control disabled, and the shifter placed in "M/S" mode (all these settings place the car in its highest, and loudest, performance mode) there is no noticeable increase in engine sound, except during wide open throttle you can hear a slight increase in induction noise. I am probably going to put the stock box back in as it does not draw in warm air from the engine compartment like the MPPK lower air box does.

Thanks lol. I almost got one and until you pointed it out I already have one in my M2. Love these boards. You're the man!

I see about 10 degree increase in intake temps when sitting at a light for extended period of time compared to the stock airbox (per my Torque app). Once rolling, there's no difference in intake temp compared to the stock airbox. The sound increase is worth the price of admission, IMO. BMW saw fit to make the part OEM on MPP Kit and the M2 so why not You could open up the stock airbox as well, but I prefer the option to return my car back to stock and have the option to make some money back.

This may be a dumb question so please excuse my ignorance but couldn't you just remove the snow valve instead of drilling a hold and accomplish the same exact thing? For those looking to modify stock not buy the MPKK one

I thought about that myself. Except the snow valve opening is smaller than the MPPK opening. And the snow valve is facing the engine (don't know if that would really make a difference; might pull in hotter air). Plus those using the Dinan intake have to block off the snow valve anyway...
