Radium Engineering Mazda Primary Injector Seat 16MM

The Radium Engineering Mazda Primary Injector Seat 16MM is designed so it adapts the supported intake manifold or cylinder head to the injector O-ring format required by a top-feed fuel-injector conversion. The machined seat provides the correct injector locating and sealing surface so an upgraded injector can be installed without improvised sleeves or spacers.

Fitment is specific to Mazda Primary; confirm the vehicle and surrounding hardware before ordering. Seat height and application vary. Confirm the exact engine/manifold and injector dimensions for the selected part.
