Airbox on now, dip stick moved and MAF is attached too into the air flow.
Rear stromung back boxes on too. look good and should sound good too.
nasty pioneer pop out screen thing out and OEM business CD in so looks much better
onwards and upwards. big thanks to BMR in dartford as ever.

Please don’t drive it with the MAF sensor plugged in there, the sensor must sit in the housing in which it was designed/mapped.
The MAF sensor is calibrated with a housing of known volume/diameter, if you change the diameter of the housing you’ll change the reported airflow.

I did not comment before as I am not familiar with the MAF on this specific car and did not know hot it would be mounted but I had a look at the part online as well as the pictures and think I can bring some more insight:
I will join Martyn and Tom here and advise against using the MAF with that new mounting position. If the MAF was inclusive of a piece of tube and honey comb it could have been reaplied (though could have run into issues with turbulences or other weird phenomenons). The main issue I am having with the instal here is that the location has changed a lot. The MAF is measuring an air speed (as well as density) to figure out the flow of air. This speed is dependant on the area of the pipe it is mounted to which has changed as it is now on the airbox so the sensor will end up reading false values.
I would be very surprised if this has been doned by other people and worked.

The only way I can see it working is if you graft the original MAF tube in front of the airbox, so air entering the airbox passes through the MAF housing first.

You'll need an alpha n tune to run that box. That Def ain't gonna work that way.
Prob wouldent hurt to put a filter on the front of that either. I ran one of those boxes for a good while. That however looks like a grey market box. There was also zero need to bolt that dipstick to the side of the box as it can't go anywhere anyways, also when you looking where to plumb your temp sensor (if you go alpha N) you'll want to mount it as far away from the hot engine as possible. (Hint: the far side where the air enters the box is a reasonable position. )
I also gotta ask what is going on with the carter rebreather tube on your CF box? Normally these sit up perpendicular upwards, not on an angle like that? Did you dislodge it and re-glue it in its current position?
Anyways, that's just esthetics, but you'll need to sort either a tune or properly run the MAF. Good luck, if you need any help , feel free to ping me.

thanks for the all inputs.
going to remove the MAF and get the remap done to make sure its right for the box . put the temp sensor in there maybe as discussed above
tbh I dont know anything about changes made to it and location of things, just bought it and handed it over for fit
there is going to be a filter on the end of the box

all done, running well and the carbon box makes a great bark and sound right through the rev range
MAF delete and remap done to cope with the removal of the MAF.
Filter has been put together for the end piece as well so very happy with the outcome.
Stromung back boxes not for me and tried them out - going to a new home on here once they are off this week.

filter on. car went back for a slight change to the map. the OEM air box feed sits well up to it and just enough room. I might get a black filter so less obvious and paint the filter cage in black.
new windscreen and external rubber as had perished and cracked
back to OEM back boxes and stromungs sold on here.
off to Jack at Royal steering wheels for new wheel. leather, M stitching, Red centre at 12, perforated on the side areas. current wheel is proper shagged.
pretty much done then. drive and enjoy the up front barking
fancy a euro trip in the summer to Ring then BMW museum. maybe stop off at porsche in stuttgart too and then some alpine passes.

went to see Jack at Royal steering wheels in Great Missenden and amazing job as ever
the steering wheel was original I think and very tired and worn
have gone for M stitching, red stripe at 12 oclock with smooth leather then perf on the sides. I love it. massive improvement in looks and feel to what was on before.

car through MOT and no advisories at all. result
OEM e46 m3 strut brace added
silver door handle covers wrapped in gloss black to match the piano black interior (I always hated the silver on the door handles)

NLW73,
A question about your Maf setup, I was under the impression that the stock Maf sensor was programmed for the stock 4" opening, your location for the Maf looks much wider than 4".
How did you reconfigure the Maf sensor to operate in that larger space? Did you run in to any problems while tuning?
Thanks
