I have a UK/Euro air box for N52 engines (325i/330i?) for sale. I think these are popular for conversions in the US? The top cover has been scuffed a bit, probably only needs a light sand and seal but otherwise all good. Not sure of the price but does $150 sound fair? and whatever the delivery is calculated at. I know these go for £400 new here.
Can someone move this to the correct section, cheers
