Description

20v 4age – Intake manifold vacuum block off plate

 

This small aluminium plate directly replaces the original vacuum chamber on the top of the 20V 4age intake manifold. This results in a much more simple and neat looking intake manifold. It will however remove all the air feeds from this chamber such as the idle control, cam cover breather and others.

 

UPDATE: These are now supplied with Gold coloured flange hex bolts for an OEM look.

 

Installation notes

– To seal off this plate against the manifold either re-use the existing gasket, use some gasket paper to cut a custom gasket or use some sealant / gasket maker.

– If the original ECU is used then the idle controller (ISCV) will still need to be electrically plugged in otherwise the ECU will have a fault code. In regard to the ISCV’s air piping it does not however still need to be plumbed into the idle control system and the ISCV can instead just be left mounted in any location while electrically plugged in.

– After the installation of this plate the idle can be controlled by equally adjusting each of the four individual throttle blade stopper screws. These are located at the base of each throttle to adjust how far the throttle blades are able to shut when there is no tension on the throttle cable. Note: These four screws need to be equally adjusted so that all four throttles close to the same position.
