996 - 997 - 991.1 - TT - GT2 - GT3 - Cup Cylinder housing set watertanks for Porsche 3.8 - 4.3 liter engines

In order to optimize the temperature balance of the Porsche engines listed, the AMS water tanks are
used as a replacement for the series product. Our special water tank is particularly useful when the
displacement is increased and can be used up to an increased bore size of Ø106 mm, thus for GT3
and Cup engines up to 4.3 liters. 

• Optimized heat dissipation through increased cooling water volume and integrated cooling fins.
• Optimized water circulation around the cylinders through increased cross-sections, thus better
  heat dissipation.
• Optimized water tank rigidity is also provided when the displacement is increased thanks to
  the modified design of the water tank. The series water tanks are designed for a displacement
  of 3.8 liters or  Ø102 mm

Depending on the cylinder configuration, the water tanks are drilled together with the engine blocks
on a CNC milling machine to guarantee an optimal fit and perfect function.

The original bolts must be used for the screw connection;
there is not enough wall thickness for thicker bolts.
