Product Details
Unit 8-97382-945-0 is a sealed P-type mechanical injector cartridge designed for Isuzu 4HK1-TC (5.2 L) and 4JJ1-TC (2.5 L) four-cylinder diesel powertrains fitted to NPR300/NQR450 medium-duty trucks and industrial equipment versions. This assembly integrates the needle valve, ND-DLLA specification 5-hole nozzle tip (approx. 0.23 mm orifice, 148° spray angle), compression spring and adjusting screw within an M22×1.5 threaded housing, sealed in position by a copper sealing washer. The popping pressure ranges from 130–145 bar, adjustable via shim stacks. Constructed from nitrided alloy steel, the unit features 19 mm wrench flats, a 60° sealing seat and a 5.50 mm guide bore; it belongs to the ZEXEL ND-P medium series, sitting between the 5.00 mm bore variant 105118-8302 and Bosch 131 series with a 6.00 mm bore. Interchangeable part numbers include Isuzu 8-97382-945-0, ZEXEL 105118-8345 equivalent series and legacy Bosch exchange series 9 430 614 xxx.

Our Advantages
Precision-tuned channel profiles facilitate swift pressure regulation, delivering consistent power output across an extensive operating spectrum and curbing fuel consumption during idle operation and constant-speed highway travel. Every finished unit receives separate functional evaluation on certified calibration benches to verify opening pressure thresholds, long-term sealing performance and spray distribution characteristics, ensuring consistent quality between all production batches. Constructed as a direct interchangeable spare part complying with OEM installation specifications, it fits seamlessly without field modification during maintenance work and substantially reduces equipment downtime. The robust structural design guarantees prolonged reliable service for commercial fleet vehicles and stationary emergency power generators.
FAQ
1.Does 8-97382-945-0 share the Ø5.00 mm ND-P guide bore and 0.75 mm seat-land geometry of 105118-8302, or is the 945-0 a different ZEXEL sub-class?
945-0 inherits ND-P Ø5.00 mm conduit and 0.75 mm seating rim. Adds 1.0 mm loftier spring column for 140 bar 4KH1-TC pack. M20/60°/stem identical-casings interchangeable, but 945-0 stack in 8302 shell crushes setter 0.8 mm, breaks calibration. Fit stack-aware.
2.At 6000 hr on a 4JH1-TC, does 8-97382-945-0 degrade guide-first (like 105118-8302) or seat-ridge-first (like Bosch 131-series)?
ND-P dual-path wear: conduit ovals ~5500 hr, crest forms ~5800 hr (conduit first 300 hr). At 140 bar static, crest →5600 hr, conduit →5700 hr (gap 100 hr). 15 bar drift + clean backflow = crest leak; 18 bar + rising backflow = conduit oval. Not Bosch 131/191.
