Denso 195500-4450 Fuel Injector Assembly

The Denso 195500-4450 is a high-impedance EV6 long-body fuel injector designed for the secondary injection circuit of the Mazda 13B-MSP Renesis rotary engine. It utilizes a 4-hole disc nozzle pattern for optimized fuel atomization in the rotary combustion chamber. The injector operates at a standard rail pressure of 3 bar (43.5 psi) with a calibrated flow rate of 425 cc/min (N-Heptane) and a coil resistance of 13.8 ohms. It features a Sumitomo electrical connector and OEM-standard fitment for direct replacement without modification. This component is critical for maintaining proper air-fuel ratios and cold-start performance in the specified Mazda RX-8 applications.
