1. Cost: The Cobb fuel pressure regulator is more expensive than the OEM regulator. However, many users argue that the performance benefits and durability make the investment worthwhile.

2. Potential for Increased Emissions: Some users have reported an increase in emissions after installing the Cobb fuel pressure regulator. This is because the regulator allows for more fuel to be delivered to the engine, which can lead to more unburned fuel exiting the exhaust. However, this is not a concern for everyone, and the overall environmental impact is likely to be minimal.

3. Potential for Check Engine Light: Some users have reported a check engine light after installing the Cobb fuel pressure regulator. This is typically due to the ECU detecting a change in fuel pressure and needing to be recalibrated. This can be remedied by using a fuel pressure gauge to ensure the regulator is set to the correct pressure, or by using a tool like Cobb's Accessport to reflash the ECU.

The Cobb 315250 Fuel Pressure Regulator for Subaru WRX STI is a worthwhile upgrade for those looking to enhance their vehicle's performance. While it comes with some potential drawbacks, such as cost and the potential for increased emissions or check engine lights, the benefits, including improved fuel delivery, ease of installation, durability, and adjustability, often outweigh the cons. If you're looking to maximize the performance of your Subaru WRX STI, the Cobb fuel pressure regulator is a solid investment.

If you're considering purchasing the Cobb 315250 Fuel Pressure Regulator for your Subaru WRX STI, I would recommend taking the time to research the installation process and ensure that you have the necessary tools and knowledge to install it yourself. Additionally, be prepared for the potential for increased emissions or check engine lights, and be prepared to address these issues if they arise. Overall, the Cobb fuel pressure regulator is a high-quality upgrade that can provide significant performance benefits for your Subaru WRX STI.
