387-9434 is supplied as a remanufactured replacement injector assembly. Cross-reference numbers: 387-9434, 387-9432. Application recorded for this part: KAT. This is the last precision component in the fuel path. Everything upstream exists to deliver clean fuel at stable pressure; this unit decides when combustion starts and how completely the charge burns. That is why injector condition shows up so directly in noise, smoke and emissions. Watch for hard hot starting, uneven idle, visible smoke, a misfire that clears when the engine is revved, and consumption creeping up without any change in operating conditions. Do a return-flow check before buying anything. Comparing leak-off volumes between cylinders takes minutes, and if one injector returns far more than its neighbours, that single test has answered the question. Fitment notes: injectors on the same engine wear together. Replacing only the failed unit often leaves the others close behind, and a single new injector reading differently from its neighbours will cause exactly the rough running you were trying to fix. Replacing as a matched set avoids that. Always fit new copper sealing washers and seals — used washers rarely seal a second time — and where the system requires injector classification or IQA codes, have them programmed to the ECU after fitting. Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
