Nissan 300ZX (Z32) VG30DE / VG30DETT Fuel Injector Cleaning & Flow Testing

The JECS A46-Z00 is a MPFI side-feed (port injection) fuel injector used in Nissan 300ZX (Z32) 3.0L V6 — VG30DE naturally aspirated and VG30DETT twin turbo (1990-1996), also the JDM Fairlady Z. JECS side-feed injector, body code A46. The Z32 is one of the few platforms that runs a side-feed injector rather than the usual top-feed design.. We ultrasonic-clean and flow-test injectors like this one in our shop, then send back before-and-after data so you know exactly what you're getting.
