I have had a standard air box, two cone filters. an RS500 box and now my custom box.

We have tested on the rollers and power is ALWAYS better with a box.

How vaild that test is on the road is anyones guess but on thing I will say is that anyone who thinks that a unshielded cone is ok once the car is moving is wrong as both of my plastic airbox's were melted at the side closest to the turbo so that proves that the air around he is very hot indeed.
