The Snow Performance throttle body spacer injection plate fits Subaru WRX and STI 2.5L models and provides a simple way to mount water-meth or nitrous nozzles between the throttle body and intake manifold. It supplies two 1/8" NPT ports for nozzle placement. Snow Performance notes a required solenoid upgrade to prevent vacuum siphoning when using a throttle-body mount configuration.
