The filter is also easy to clean and can be reused multiple times, saving you money in the long run.

The intake tubing is made from mandrel-bent aluminum, ensuring a smooth and efficient airflow path to the engine. The tubing is also coated with a durable, heat-resistant powder coat finish to protect against engine heat and corrosion.

The AEM 21-874C Air Intake System is easy to install, with all necessary hardware included. The system can be installed in about an hour, and no modifications to the engine bay are required. The system also comes with a detailed installation manual to guide you through the process.

This intake system is not only a performance upgrade but also a stylish one. The AEM logo is prominently displayed on the air box, adding a touch of sophistication to your Forester's engine bay.

In summary, the AEM 21-874C Air Intake System is a high-quality, high-performance intake system designed specifically for the 2018-2025 Subaru Forester 2.5L models. It delivers increased airflow to the engine for improved power and acceleration, and it is easy to install and maintain. With its high-flow, dry-filtered air box, high-flow air filter, mandrel-bent aluminum tubing, and durable construction, this intake system is the perfect choice for Subaru Forester owners looking to take their vehicle's performance to the next level.

This intake system aims to enhance the engine's performance by improving airflow and filtering out contaminants. Here are some pros and cons of installing this intake system on your Subaru Forester:

1. Increased Horsepower and Torque: The AEM intake system can provide a noticeable increase in horsepower and torque, resulting in improved engine performance and acceleration.

2. Cold Air Intake Design: The cold air intake design helps to cool down the incoming air before it enters the engine, which can lead to better combustion and increased fuel efficiency.

4. Easy Installation: The AEM intake system is relatively easy to install, and most users can complete the process in under 2 hours.

1. Higher Fuel Consumption: Although the intake system can lead to increased fuel efficiency due to better combustion, some users have reported higher fuel consumption after installation.

2. Expensive: The AEM intake system is more expensive than the stock intake, which may deter some buyers.

3. Potential Check Engine Light: In some cases, installing the AEM intake system may trigger the check engine light due to changes in the air/fuel mixture.

4. Loud Intake Sound: Some users have reported that the intake sound can be quite loud, which may not be desirable for everyone.

The AEM 21-874C Cold Air Intake System offers several benefits for the 2018-2025 Subaru Forester 2.5L engines, including increased horsepower and torque, improved engine sound, and a cold air intake design. However, it also comes with some drawbacks, such as a higher price tag, potential check engine light issues, and increased fuel consumption. Ultimately, the decision to purchase this intake system depends on your personal preferences, driving style, and budget. If you're looking for improved engine performance and enjoy the sound of a more aggressive intake, then the AEM intake system may be worth considering. However, if you're more concerned about fuel efficiency or a quieter driving experience, then it may be best to stick with the stock intake.
