I keep looking at the K&N filter, mainly from an aesthetic point of view, cos the big black airbox on my cvh is pretty ugly.(and I's like to hear a bit more induction roar. I have read about possible freezing in cold weather - are you saying this isnt a problem in the morgan? I use my car all year so cold weather issues would be a nuisance - Also does water pouring in through the louvres in heavy rain or when washing?
Also, does anyone know if the K&N part number quoted by cereal at the top of the thread is the correct one for my '88 cvh
