I've been seeing alot of pro touring cars lately that are using vintage air but are not using the factory unit to adjust the air. They have all had 4 billet ***** that controls the air. Looked really nice and clean. Anyone have any idea what, why, how. where people are doing it and where I can get a set up like that?

 

They advertise the billet ***** on their web page in the catalog. The standard rotary ***** are advertised as a replacement to the stock controls.

 

Good to know. Must have missed that. Thanks
