I did a quick Google search, and found this for you...Do you or anybody know if the exhaust valve will fit the A4 as the A4 it uses the exhaust valve wit the red end a appears to be fitted to the valve in the picture
I take it lavenm that you're now going to keep that gorgeous A4 GRELLO you posted up for sale not so long ago?Would you do an A4 bolt, A4 ram, COPS, exhaust valve set, cops pin and the feed neck ring and washers from last photo for £35 as it can all be posted for one charge.
