Recirculation Valve Spring - K03/K04/K06 Forge Recirc Valve
Recirculation Valve Spring - K03/K04/K06 Forge Recirc Valve

Replacement Spring for K03/K04/K06 In Turbo Forge Alloy Aftermarket Recirculation Valve. 

Valve Spring color coding:
Green - Standard Cars/Mildly Tuned
Yellow - Mapped Cars to 300bhp
Blue - K06 Hybrid Turbo

Valve Spring Colour Coding: The weakest spring is GREEN, followed by YELLOW, and BLUE. This represents an increase of 25%, 50%, and 75%.

*The above should only be considered as a guideline*

Please note - fitting a stronger spring into a valve will not increase boost pressure unless existing pressure is being lost. Failure to allow the valve to operate by installing a spring which is to strong may cause damage to the turbocharger.

The spring is designed for the replacement aftermarket K03/K04/K06 recirculation valve, as used in:
Astra G Z20LET
Zafira A Z20LET
Astra H Z16LEx and Z20LEx
Zafria B Z20LEx
Corsa D Z16LEx
Meriva A Z16LET
