- Porsche 944 2.5L 8V 1982-87
The injector 944 606 110 01 is made for the early Porsche 944 with the 2.5L 8-valve inline-4 engine (1982–85). The injectors deliver a fine, metered spray of fuel into the intake port (or manifold) synchronized with engine control signals (pulse width). The engine’s control module (DME) varies how long the injector is open (duty cycle) to control air/fuel ratio. required is 4 per car. Price is for each.
These injectors are part of the Bosch-style / early Porsche / Jetronic fuel injection system (common to many 4-cylinder Porsches). The 944 injector 944 606 110 01 is cross-referenced with Bosch part 0280150201.

Common failure modes / issues
Clogging or partial occlusion
Deposits from fuel (e.g. varnish, gums, carbon) can accumulate on the injector nozzle or internal filter screens, restricting flow or altering spray pattern. This leads to inconsistent fuel delivery, lean condition on one cylinder, misfires, or rough idle.
Leaking (internal or external)
Injector may leak fuel when closed (i.e. dribble), due to worn needle/seat or weakened internal seals. That causes flooding, rich mixture, poor idle, or fuel smell. External leakage (o-rings degraded) can cause fuel to leak externally around injector, risking fire or vacuum leaks.
Electrical degradation
The coil windings inside can degrade (partial shorts, increased resistance, insulation breakdown) — leading to slow response, weak spray, or complete failure. Connector terminals or wiring may corrode, break, or have poor connection.
Wear / fatigue of internal moving parts
The needle, pintle, spring, and internal tolerances wear over time; that increases “dead time” (delay between signal and actual opening) and changes the effective flow versus command duty cycle. Over time, this causes imbalance between cylinders, mis-tuning, and drivability issues.
Imbalanced or mismatched injectors
Over time, injectors can drift in flow rate; if one injector flows slightly more or less than the others, cylinder fuel balance is upset. A matched set is ideal. When replacing only one injector, mismatch can worsen performance.
Aging seals / O-rings / insulator degradation
The rubber/plastic O-rings that seal the injector to the intake manifold may harden, crack or leak, causing vacuum leaks or fuel vapour escape. The body insulator or mounting flange may degrade, causing mechanical looseness.
Spray pattern deterioration
If the spray cone or atomization pattern is degraded (due to nozzle wear or damage), fuel may not vaporize correctly, leading to incomplete combustion, poorer fuel economy, or emissions issues.
Intermittent or total failure
In some cases, an injector might fail open (permanently on) or stuck (never opens). That leads to severe lean/rich condition or a dead cylinder.
