[Healeys] cold air box 3000

[Allen C Miller Jr]

i would recommend exploring racing intake tubes vs cold air box if the 
objective is to improve air flow into the manifolds. cold air box on the 
100M was to supply COLD air, not to serve as a ram air induction device. in 
fact, the cold air box as conformed can cause slight vortex disturbances 
interfering air supply to the rear intake.

i bought a period cold air box on EBAY a few years back, and in the course 
of its life the back end had been hacksawed off. i asked around and was 
advised by an old salt that racers used to do this to ensure that airflow to 
the front and rear manifolds was even, and that the intended purpose of just 
supplying good cold air was fulfilled.
