Throttle Body Size on Ford Fiesta
The throttle body size on a Ford Fiesta is 60mm. This information is based on the compatibility details provided for the Ford Fiesta throttle body assembly, which states that it is designed to fit the vehicle and has a 60mm size.
The throttle body is an important component of the engine’s intake system, regulating the amount of air that is mixed with fuel for combustion.

Does putting a bigger throttle body increase horsepower?
Increased Performance
With more air comes more performance, which is why most people add a larger throttle body to their vehicles. These throttle bodies have been dyno tested by the manufacturer to increase horsepower and torque.
Does throttle body size matter?
Too small will kill power as the engine won’t be able to draw enough air through it/them. Too large will make it difficult to control part throttle, especially at lower rpm, as even small butterfly angles will allow a significant amount of airflow.
How do I know my throttle body size?
I’ve always used the calculation formula: Engine displacement/number of cylinders x rev limit.. (For the calculation above the constants Being the 0.8 is based on VE avarage at peak for most N/A engines, and the 0.5 being of VE avarage at idle.) So 44mm throttle body be about your ball park to consider.
How much HP does a throttle body give?
Gains from a throttle body can be dependent on modifications. Generally speaking, anytime a throttle body is added, there will be some added horsepower. The amounts can range from 5-25 HP depending on what other modifications are done to the engine.
What size throttle body is a Fiesta ST?
Commonly a 60mm throttle body is used, sometimes it’s just the original 55mm bored out to 60mm or some come up from the 2.3 Duratec.
How much horsepower does a bigger throttle body add?
Gains from a throttle body can be dependent on modifications. Generally speaking, anytime a throttle body is added, there will be some added horsepower. The amounts can range from 5-25 HP depending on what other modifications are done to the engine.
How much HP does a 70mm throttle body add?
8-10 Additional Horsepower Over The Stock Throttle Body.
Can I put a bigger throttle body on my car?
Installing a larger throttle body on an otherwise stock engine running on a stock ECU will likely gain you no power and only make things worse. The ECU is programmed to expect a certain amount of airflow at any given RPM, load, and throttle position.
Is a bigger or smaller throttle body better?
Contrary to popular belief, a larger throttle opening does not reduce low-speed power, but the effect on throttle response can be dramatic. The reason is that (compared to a smaller throttle body), any throttle position will offer a sizable increase in airflow.
What happens when you install a bigger throttle body?
Upgrading an entire fuel system typically involves replacing: The throttle bodies: Bigger throttle bodies can provide greater throttle response and increased power. Fuel injectors: High-flow fuel injectors can improve the air/fuel mixture for more efficient combustion.
