What does 'top feed' mean for these injectors?

Top feed injectors have their fuel inlet on the top, where the fuel rail connects, and the spray nozzle at the bottom. This is a common design for many performance fuel injectors and is compatible with the fuel rail setup on the specified Porsche 911 models.

Why is it important for injectors to be 'flow-matched'?

Flow-matched injectors are tested and sorted so that each injector delivers very close to the same amount of fuel under a given pressure. This consistency across all cylinders helps your engine run more smoothly and efficiently, preventing issues that can arise from uneven fuel distribution.

Are these injectors compatible with all 1998-2005 Porsche 911 models?

This set is specifically designed for the non-turbo 911 models from 1998-2005 with 2.7L, 3.4L, or 3.6L engines. It's always a good idea to double-check your specific engine size and model year to ensure compatibility.
