06401K45N01: Understanding the Part Number of a Ford F-150 Fuel Injector

The Ford F-150 is a popular pickup truck known for its durability and performance. One of the critical components that contribute to its impressive performance is the fuel injector. In this article, we will delve into the world of fuel injectors and explore the meaning behind the part number 06401K45N01.

What is a Fuel Injector?

A fuel injector is a vital component of a vehicle's fuel system. Its primary function is to spray fuel into the engine's combustion chamber at the right time and in the correct amount. This process ensures efficient combustion, which ultimately affects the vehicle's performance, fuel efficiency, and emissions.

Decoding the Part Number: 06401K45N01

The part number 06401K45N01 might seem like a random sequence of numbers and letters, but it contains valuable information about the fuel injector. Let's break it down:

  • 06401: This is the basic part number assigned by Ford to identify the fuel injector.
  • K: This letter indicates the type of fuel injector. In this case, "K" represents a specific design or configuration.
  • 45: This number signifies the flow rate of the fuel injector, measured in cubic centimeters per minute (cm³/min). A higher flow rate means more fuel is delivered to the engine, which can result in increased power and performance.
  • N01: This suffix indicates the specific application of the fuel injector. In this case, "N01" is specific to the Ford F-150.


The 06401K45N01 fuel injector is a critical component of the Ford F-150's fuel system. By understanding the part number, we can gain insights into the injector's design, flow rate, and application. If you're in the market for a replacement fuel injector or looking to upgrade your F-150's performance, knowing the part number and its meaning can help you make an informed decision.
