For sale is a Genuine Revolution Aluminium AST for a Mazda RX7 FD3S. Has just come back from the polishers and so looks like new now! Includes mounting bracket as shown. Will need two copper washers for the fittings and you can reuse your OEM cap. These are now discontinued and Revolution no longer sells them. Please see last photo to show the listing in the Hyper Rev vol 123.
