Looking for the stock size of your 1993-1995 or 1999-2004 Ford Lightning? LMR has you covered!
From the factory, the OEM throttle bodies on Ford Lightnings were great for daily driving applications. They still made great power and performed well, even in full bolt-on applications. Once you started to add higher-horsepower mods, an upgraded throttle body was essential to bring in more air and ensure your engine was running as efficiently as possible. Before upgrading to a performance throttle body, it is important to know what the factory sizes were.
1993-1995 Ford Lightning Stock Throttle Body Size - 65mm
1999-2004 Ford Lightning Stock Throttle Body Size - Twin 57mm
A throttle body is a key component of your engine’s ability to run efficiently. Mounted between your air intake tube and intake manifold, the throttle body regulates the amount of air that enters your engine. On Gen 1 and Gen 2 Ford Lightnings, the throttle body is controlled by a cable which is activated by pressing the accelerator pedal. Once you press the pedal, the cable pulls the throttle body blade or blades open, allowing more air to enter your engine. 
Upgrading the throttle body on your Ford Lightning is a great way to increase horsepower and torque while getting a better throttle response with a simple bolt-on mod. However, it must be said that upgraded throttle bodies are going to perform better in applications where your engine needs additional air. For example, an upgraded throttle body on a stock truck won’t see the same gains as a truck with supporting mods such as an upgraded heads/cam combo on a Gen 1 or an upgraded supercharger on a Gen 2. 
For Gen 2 Lightning owners looking to purchase a new throttle body, you may notice that most aftermarket options feature a single-blade option vs the dual blade that the factory setup has. The factory Gen 2 throttle body utilizes two 57mm throttle bodies housed in one unit. Aftermarket throttle bodies feature a single, wide throttle body with one blade instead of two, reducing the restriction of the dual-blade setup. If you are using your truck as a street truck, either or will be just fine. If you are building a high-horsepower engine with a bigger blower, you may consult with your engine tuner to see which is best for your build.
