Did this a while back - just thought I would share
My bargain BMC CDA arrived today

Car up on axle stand

'snorkel' prised off the airbox & bolt removed with 8mm socket from underside

Bracket removed from rear of airbox with 10mm socket to ease removal

I undid electrical connectors to give more room

Airbox half way out

Result - it's out! - bit of jiggery pokery involved getting it through coolant pipes etc

Old & new

Bolts in existing airbox sheared (of course! [:P] ) while removing MAF housing (10mm socket)

I 'kinked' the fixing strap through 90º to enable fixing of CDA
http://i254.photobucket.com/albums/h...e/P5190011.jpg
I fixed the strap using the same bolts that fix the fan to the rad (8mm socket)
http://i254.photobucket.com/albums/h...e/P5190012.jpg
CDA then fixed to this using 10mm sockets
