Air Filter Assembly.

The Air Filter assembly needed  to have a Rat-Rod look. 

Not be too big and clumsy,

 and at the same time do it's job - clean the air.

We also wanted it to bolt directly onto the Electric Supercharger as 

 this could save some space.

Back to the mighty EvilBay to find a 66mm filter.

66mm Throat on each side of the Supercharger.

This is what we found!
