e46 M3 Airbox

Hi All,

So Im currently looking to get some info on airbox options out there. I was keen on the Geoff Steel Racing Airbox but stupidly waited and now with Brexit, its looking too pricey. There is a group buy at the moment for 1349 sterling delivered to Dublin (or up north). Are there any other options that are trusted? I was offered a CSL clone that came from one of the owners forums. I had seen people mention German options but cant seem to find anything online outside of the GSR and Karbonius options.

I had seen the Eventuri intake option, especially with Des Golden bing an official seller, but feel that I would regret not going for the airbox..

Thanks

Have heard some horror stories aobut their V1 airbox. Would kind of put me off them to be honest, though they seem to have good customer service. Price works out similar to a GSR intake

Yea saw that. If the company is serious about their business I would think after that incident they would make sure their quality is top notch. So could be a positive, but defo a risk, I would research it further. GSR box looks rough, weave is all over the place, its made for track cars so aesthetics not important but its meant to be solid.

I have a karbonius on my e46, couldn't fault it.

Yeah that’s very true, hopefully means their v2 is over engineered! Yeah u heard that but heard the latest version is a lot tidier and presentable

Would love one but can’t justify the cost of one! Would be over €2k before installation or any extra bits

Have a GSR box on mine. Got it in the last group but a few years ago and given I got one for my E36 too, they worked out at about 1700 for the two of them I think.

It works perfectly but it's abit function over form alright but only really an issue if wanting to show it off all the time lol.

I'll probably get a Karbonius or Streamline one when I've the new engine built.

Wouldn't be totally put off by the failures of streamlines box once they sorted the problem and Antonio fully took responsibility and offered to foot the bill of any repairs for the engine if it needed them.

One of the lads on here has one of the boxes too and Streamline contacted him straight away and he's getting another new box just in case.

I've seen an Evolve box go in shite too and think that one actually did do some damage to the engine and also have heard of Turner motorsport boxes fail.

Only ones I haven't heard of issues with are Oem csl boxes, Karbonius and GSR.

Thanks for the info, im tempted now to try the streamline one. Where did you get yours tuned? Did you go Alpha N or CSL tune?

Here is another crowd that does them, from their insta looks like they based in Poland. Quality doesn't look that great to be honest.

Tuned it on a friend's dyno here in Cork (Fionnsport)
Finbarr has worked at BMW and VAC so not many about that knows his away around them so well :)

I've a standalone ecu but I'd recommend going th CSL tune route rather than Alpha N as its much more refined.

Iv heard of Fionnsport, was actually going to try get my e30 318is tuned there (once I get it back).

Yeah I keep hearing theres a big difference between the CSL tune and the Alpha N. Would defeinitely prefer to go CSL tune route. Good to know Fionnsport can do it.

My new streamline one should be arriving in the next few days. The pics he sent look quite good. All the hose connections are not aluminium rather than printed.

Be very interested to get your opinion of it and what it’s like once installed! Are you going to get the alpha n tune or csl tune?

I already have the CSL one. I sent my ecu to the UK as it wasn’t an MSS54HP ecu but the earlier MSS54 which doesn’t support the CSL setup with a MAP sensor.

Im nearly certain I have the later generation that doesnt need tinkering with. Any recommendations on who to do the tune and fitting of it?

Can’t recommend someone to do the map unfortunately. Baris ecu in the uk can mod your ecu but as far as the software mods go your on your own.

Can you elaborate on that? Mine is 01 so I would assume I have earlier ECU. If I were to run airbox do I need to send my ECU to get it coded?

Check out this link, it’s by Mike/M3Carbon1 on M3 cutters.

He was recommended to me by Will at Geoff Steel when I contacted them about their airbox.

I can’t vouch for him as I didn’t go any further with it but his post is very informative.

Hope you find it useful.

You need to send the earlier ecu away to have the memory upgraded. Basically the CSL requires a chip with more memory which the non hp ecu doesn’t not have.

Absolutley get in contact with Mike. The reason I say I can’t comment is he isn’t finished with mine yet.

Just wondering if you got and installed your streamline airbox Smokey? Curious to hear your thoughts on it

Best money I ever spent, if I had my time back I’d have bought one with the car.

Time without an airbox is time wasted.

Any issues with the streamline box? Happy with the quality and all? Did you install it yourself?

The new one is much better quality. No issues this time, filter fits properly etc.

Fitted it myself. Go on cutters there’s a good thread on all the bits you need to get it fitted, I think it refers to a karbonius box but they’re all the same.
22-05-21, 16:22

As Smokey says, there's very little to fitting them. Rather than going all the way over on alpha N or a base map on the standalone ecu as we didn't have time before going, I brought my airbox with me when went to the 'Ring. Fitted the airbox in an hour in the Devil's diner carpark while track was closed :D

Thanks, have been checking out that thread. Only question I have is sourcing the right MAP sensor

Just go on eBay and get the cheapest 1 bar GM map sensor you can find.
