What Is the Mustang Carbon Trap?
The Mustang carbon trap, also known as a hydrocarbon trap, is an emissions-related component installed in the intake system of certain Mustang models, particularly the 2022 and newer S650 generation. Its primary function is to trap and store unburned fuel vapors—also known as hydrocarbons—before they can be released into the environment. These hydrocarbons are typically produced during the intake cycle when the air-fuel mixture enters the engine but doesn’t fully combust.
Ford added the carbon trap as part of efforts to comply with strict emissions regulations, such as those set by the Environmental Protection Agency (EPA) and California Air Resources Board (CARB). By capturing these fuel vapors, the carbon trap helps reduce emissions and improve the car’s overall environmental footprint.
How Does the Carbon Trap Work?
The carbon trap consists of a charcoal-based filter located in the air intake path, where it captures vaporized fuel before it enters the intake manifold. This prevents fuel vapors from being released directly into the atmosphere and helps the engine run cleaner by minimizing harmful emissions.
However, while the carbon trap plays a significant role in reducing emissions, it also introduces a degree of restriction in the intake airflow. This can affect engine performance by slightly limiting the amount of air entering the combustion chambers, which is essential for efficient combustion.
What Does Mustang Carbon Trap Do?
The presence of the carbon trap in the Mustang intake system can affect the engine’s airflow and overall performance. While it plays a crucial role in reducing emissions, it’s essential to understand how it might limit power output and throttle response. Let’s break down how the carbon trap impacts your Mustang’s performance in both stock and modified setups.
Performance Gains and Losses
The Mustang carbon trap can have a noticeable effect on your car’s performance, particularly in models equipped with the Gen 3 Coyote engine. The restriction it causes in the airflow path may reduce horsepower, especially when the engine is under heavy load or at higher RPMs.
In fact, some Mustang enthusiasts have noticed a modest decrease in horsepower due to the airflow limitations introduced by the carbon trap. This decrease may be as much as 10 horsepower in some instances. While this might not be hugely significant in everyday driving, the cumulative effect can be noticeable in high-performance or modified Mustang vehicles, particularly in racing conditions or spirited driving.
Does Removing the Carbon Trap Improve Performance?
The idea behind removing the carbon trap is to reduce intake restrictions and improve overall airflow. When the carbon trap is deleted, air can move more freely through the intake, which potentially results in an increase in horsepower and throttle response. Some users have reported gains of up to 18 horsepower by removing the carbon trap.
However, it’s important to note that the performance gains from removing the carbon trap are not guaranteed. The improvements will depend on several factors, including the type of modifications you’ve made to your Mustang, whether you perform a retune after removing the trap, and the specific conditions under which you’re driving.
