You need to know how much room you have between the carb flange and the underside of the bonnet, then you could get the appropriate one of these..................

You could even put one of these on, then have a remote air filter built in the gap over the radiator, but again you need to know if it'll fit under the bonnet.

With a filter like this (depending on size of hose) http://www.ebay.co.uk/itm/GEE-3-High-Flow-Air-filter-Universal-Cold-Air-Intake-Cone-89-90mm-Inlet-Blue-/251966690115?hash=item3aaa629343:g:YoUAAOSwrklVXDbY

 

I would advise that you DON'T get one like this, unless you really want a pair of dimples in the bonnet made by the fixing nuts.

You will be limited as the above may protrude out off bonnet , but I would also include ram pipes too.

 

Without going into the maths, IF you don't mind cutting a hole in bonnet and going big, then fit ram pipes inside with a 25mm clearance..i.e. 100mm high filter, 75mm ram pipes.

 

Longest is better for torque across the rev range.

 

Just something to consider.
