geoff steel racing are offering their carbon airbox for S50B32 (E36 M3 engine) for approx £600 (check that figure on the thread, as its from memory!) in a group buy of 10 or more on the M3cutters forum
http://forums.m3cutters.co.uk/showthread.php?t=56404
was also doing a group buy on S54 ones too (not sure if these GSR boxes will fit in an MC, but worth an ask at those prices?!)
both group buys are mentioned in that thread somewhere

Following on from Cemalakcal's link in the picture thread..
This looks very interesting. retains the factory MAF sensor so I assume it runs standard management.
Quality and heat sheilding look very good too.

Although the carbon box looks nice, I bet it makes less power than OEM. Are there any performance figures for it?/// Exdos ///

No prices or performance info unfortunately. I can't find very much information on it bar the website.
Most race s50's / s54's are running carbon air boxes of a similar design ( although on seperate management with maf delete) I think the heat sheild and air deflector on this will also help.KW V3, H&R arbs, H&R 12mm Spacers, Weichers Strut Brace, Ireland Engineering Bushes, Uprated rear top mounts,swapped front top mounts, EBC Yellows, Simota CAI, Supersprint Exhaust, Shadow chrome Roadstars

1. The photo below shows the interior of the airbox and the way that the trumpets are located would suggest that the airflow of the front cylinders will be favoured, particularly at high flow rates at high rpms, whereas the OEM air plenum has a centrally located inlet duct, which tends to give more even airflow to all 6 cylinders.
2. The intake into the airbox is the same size as OEM, as shown by the use of the screens before the MAF in the photo below, so there is no benefit from a bigger less restricted air intake operating under Alpha-n management.
3. The shield around the airbox doesn't create a seal as shown by the big gap behind the MAF sensor in the photo below. As such the intake doesn't benefit from the ram-effect because the intake isn't a sealed system.
The OEM air intake really is an excellent design for performance, especially with a few specific mods and a more free flowing exhaust./// Exdos ///

They are vaild arguments alright..
Though I do think it would be next to impossible to create a full seal at the cone due to the fact the airbox is rigid and ethier the airbox or the sheild would crack as the engine moves as it comes on / off power with the heat sheild being fixed to the body. Unless a rubber boot connected the cone as the oem airbox connects to the air filter unit.
The M3 CSL oem airbox has no sheild and is more or less open to the engine bay, the inlet is at least 3 times the size of a maf unit though.
I also wonder why they desinged the interior of the air box with the trumpets in such a way. It would of been easier for the manufacturing process to leave them flat.
I am trying to find some more information on the product , not having much luck though.Last edited by UJM3; 27-12-2012, 03:06 PM.KW V3, H&R arbs, H&R 12mm Spacers, Weichers Strut Brace, Ireland Engineering Bushes, Uprated rear top mounts,swapped front top mounts, EBC Yellows, Simota CAI, Supersprint Exhaust, Shadow chrome Roadstars
