Diverter Valve Springs - Green
Part Number: FMDVSU110G

Valve Spring colour coding
Green - 6-8 PSI
Yellow - 10-12 PSI
Blue - 14-16 PSI
Red - 18-20 PSI
Please Note:
The quoted spring pressure (Psi) relates to the un-assisted clamping force of the spring and should NOT be taken as an equivalent to boost pressure when determining suitability.
Once a valve is fitted to a car it is subjected to various pressures that act upon the diaphragm or piston to aid its respective ability to seal or hold boost. An example of this, would be when using a FMCL007P valve on a 1.8T engine as found in the TT 225hp.
The boost pressure on a "chipped" car can peak at 26psi. The recommended spring would be the Green or Yellow
