Looking at the air intake of my 1996 Ford E350 (7.5L) van it looks less than ideal. The smallish air box sits atop of the radiator, the air intake scoop also looks too small. I was thinking of a more conventional air box placed in the space normally occupied by the second battery in diesel applications. Behind the passenger side headlight. Is this a worthwhile modification in terms of efficiency (cooler denser air) or am I just wasting time and money?
