The Rosko Racing H22 Euro-R idle air control valve adapter plate was designed so that you can use a USDM 2 wire H22 IACV on your Euro-R intake manifold. It is fully CNC machined from 6061 series aluminum and ready to bolt on. Unlike some of the other adapters out there, there is no modifying or grinding of the IACV required. Each adapter also comes with the necessary bolts for installation of a 2 wire H22 IACV.
Note: This adapter also works with the F23a intake manifold. This is also compatible with F20b and H23a if and only if the IACV is mounted to the rear of the manifold.
