hey and welcome to the site mate
more air doesnt always mean more power. most induction kits draw in the warm air from around the engine.
try looking for the typhoon kits as they place the filter away from the engine, normally in the front wing, to allow it access to the cold denser air.
if you do go down the induction kit way see if you can fit it inside your airbox or build a shroud for it and fit some ducting to supply the fresh air
