[Healeys] air filter

These Cold Air Intake ('CAI') setups are all the rage with tuners and 
hotrodders.  Some production cars--like new Mustang GTs--have them 
fitted as well.  Donald and Geoff thought they were a good idea, as the 
100M had an early implementation (although I remember a 100M racer who 
claimed straight ram pipes worked better--cold air notwithstanding).  
Usually, they're claimed to give a few percent HP increase, depending on 
the car.

Would love to have a nice setup for a Big Healey.  Might make a set of 
headers worthwhile.
