Hello Gerald
Are you running hotwire (Lucas 14CUX) injection?
K&N do a nice cone filter (Rimmer brothers, RPI, etc) which is great.
You will have to slice off the tube portion of the air filter box from your donor vehicle near the point where it connects to the air flow meter(about an inch along from the meter end) and the fix the filter to this - then you have your connection.
Makes a lovely neat job - if you didn't get the filter with your engine then a new plastic air filter box (top section - you don't need the main bit) is only 19 quid from Land Rover or a tenner from a breaker.
