About this part
23600-54171 is supplied as a remanufactured replacement fuel injection part. Cross-reference numbers: 23600-54171, 2360054171. Application recorded for this part: Fits Toyota — 5L 3L.
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.
It costs little to confirm the diagnosis first. Compare return flow between cylinders and cut each injector in turn on a scan tool; if one cylinder makes no difference to running quality, that is your culprit.
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.
How we build it: the unit is fully disassembled, cleaned and measured, not simply resealed. Wear items — seals, springs, and where clearance is out of specification the plunger and barrel or nozzle assemblies — are replaced rather than reused. Sealing faces and bores are re-machined back to original clearances, then the unit is calibrated and run on a bench with delivery, return flow, opening pressure and leakage recorded. Anything outside specification does not ship. Test sheets for your specific units are available on request. Covered by a 12-month warranty.
