here we have my astra cdti airbox with filter inside, box has never been used got it for my astra gsi but never got round to fitting it and now gsi has gone i have no use for it, have 98% of the pipe work just missing the turbo silicone bend, also included is the astra vxr maf sensor again never been used and bought for my gsi never got to fit it. very sought after MOD for the mk4 astra gsi, and hard to come by so grab yourself a bargain
