One of the biggest eye sore’s in the R-35 engine bay is the factory coolant expansion tank. AMS, who has been busy making these cars reach full flannel, has developed their Performance Coolant Expansion Tank. This beautiful piece has been crafted from 100% 6061 aluminum construction that will still work with the stock, or any aftermarket radiator cap.
This coolant expansion tank is a simple bolt-on installation that provides an additional 50% increase in coolant capacity over the factory expansion tank, so it will hold a total of 3 liters.
Comes with the very authorative Alpha logo, and is hand-welded with a clean black powder-coated finish.
