4age 20v – Cooling conversion kit – V1 / V2 to V4 upgrade kit

For those who have either of our previous model cooling kits (V1 or V2) and wish to change to the latest version. This will come with all the components of the new kit as seen here with the exception of the components for the rear bypass plate and the side block off plate next to the extractor flange.


Parts options

– Heater use: This kit is available with the option of a heater provision. NOTE: A heater option can only be used when there is an existing barb / plug in the rear bypass plate. The heater compatible kit features a barb for the water feed outlet in the rear bypass housing, a return feed in the thermostat housing, a joiner hose to the original heater pipe and the relevant clamps. These parts completely clear the OEM knock sensor which is critical for the use of the original ECU.

– Custom options: For those who require a different size heater water feed or something different such as a turbo water feed then please make a note in the “comments” box that can be seen during the checkout and then send an email with the relevant request. Many different size barbs are kept in stock.
