    You may have a squarish looking baffle (doubt it though), but not a restrictor if it's more air you want to change the note. Lot of older BMs had a little cone pipe you could remove from the air box intake. I would just replace the air box with a CAI as you suggested . I've also seen a couple of air boxes before where the owners had drilled the box and fed air in from the ducts in the bumper... 'Good luck in the wet' I'd say to them

    Does anyone know if this is a dry or oiled filter?

    Edit - Just found out it's oiled - this shouldn't be a problem as it's pre-oiled right? I assume the issues with the MAF sensor only arise when the filter has been cleaned and re-oiled and that no one has experienced problems with an oiled filter during the first use "straight out of the box"?

    That is a dry cotton filter, but some say you can oil it . Also look into AFE filters as they do both varieties

    One thing to note about dry performance filters. They may let more air in but they also let more dirt in as well

    Neal - cheers for the info. I guess it's a trade off between filtration and volume of air let through the filter.

    Ended up buying the filter for £30 from a local shop (hence the sudden question about the BMC, had seen it on sale and wanted to pick it up as it was the last one in the store).

    Gonna go install it now, will also keep an eye out for the baffle!

    Just back from a fairly long spin after installing the filter. Now, I don't know whether this is just placebo effect, or even just the fact that I was now actually paying attention to the throttle response, pick up, sound etc, but I do think there is an improvement.

    I definitely hear a difference in the 3-4k rpm range, a subtle but definite "growl" is there now. There does seem to be a bit more to the engine note at all speeds (and revs), but I don't know whether this is imagined or just never noticed before...I know I like it tho!

    Pick up definitely isn't harmed, and the car feels great but I wouldn't say I can feel any improvement. I may swap back the old filter when I have some time and try and do a proper back to back to see if the differences are as big they appear to be.

    For 30-40 quid, i don't think you can really go wrong, especially if your oem one needs replacing anyway. Incidentally, my old filter didn't appear to be that dirty, so in a way I'm quite happy with the results, because I know any perceived improvement isn't just due to switching from an old grubby filter to a fresh new one.

    Edit - Didn't fully open up the airbox, just enough to slide the filter so didn't get to search for the baffle, but may open her up fully next wkd, looks a bit more time consuming to do, but can then have a proper look for any type of baffle, prolly nothing in there, but worth a peek...
