As the title, I have a number of 39mm diameter titanium inlet valves manufactured by Zanzi of Italy for a 996RS. Part number DUC 210-1-026-1A M-1 VA, 7mm shaft diameter and 106mm overall length. These are brand new and I'm looking for £300 for a set of 4, delivered although this is negotiable. PM me if interested, Andy Edited to confirm that these valves only fit the 996RS as standard. Edited again to add Part number, shaft dia. and overall length. Price negotiable.
Just updated this post to add some sizes in case someone is lookng to increase the size of their inlet valve. Appreciate that this has a very small target audience so price is negotiable as always. Andy
