0280156101 Porsche Cayenne 911 Petrol Fuel Injector – OEM Used & Tested

Descriere

This Porsche petrol fuel injector is a genuine OEM electromagnetic fuel metering component for Porsche Cayenne and 911 petrol engines. Primary OEM number 0280156101, a Bosch injector number used by Porsche. It is designed to open and close on command from the engine control unit, delivering a precise, finely atomized spray of fuel into the intake port so that fuel and air mix evenly before combustion takes place in the cylinder.

Its job is to deliver the exact amount of fuel each cylinder needs at every load and engine speed, with a stable spray pattern and a quick, repeatable opening and closing response on every cycle. A properly working injector supports smooth idle, sharp throttle response, stable fuel trims, reasonable fuel economy and correct operation of the fuel system and emissions control as a whole.

Common signs of a faulty unit include misfires on one cylinder, rough or uneven idle, hard starting, hesitation under acceleration, higher fuel consumption, a raw fuel smell and lean or rich mixture fault codes on one bank. When an injector leaks, clogs or sticks, the engine may run unevenly, lose power, overheat a cylinder or damage the catalytic converter and shorten engine life over time.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 0280156101 before ordering. Professional installation is recommended, and a fuel pressure check, new seals and O-rings, injector balance test and scan tool diagnosis are advised where applicable.
