FLI’s Proven Subaru Power Packages Refined

Fine Line Imports (FLI) has established itself as a top provider of high-performance, high-quality Subaru parts. FLI is famous for its advanced Subaru power packages that guarantee an increase in horsepower and torque, improved reliability and durability, and an overall enhanced driving experience. In recent years, FLI has continually refined its power packages to ensure every component is optimized for maximum output. This blog post will highlight FLI’s proven Subaru power packages and the refined features that make them a popular choice for performance enthusiasts.

What Is a Power Package?

A power package is a customized set of parts designed to increase the performance of a vehicle. FLI’s power packages cater to Subaru models from the Impreza, WRX, and STI to the Legacy GT, Forester, and Outback. These vehicles come with different types of engines, including the popular EJ20, EJ25, and FA20, each designed to deliver varying horsepower, torque, and overall speed.

FLI offers several power packages that cater to each vehicle model and performance needs. The packages comprise specific parts such as exhaust systems, turbochargers, intercoolers, intake systems, and ECUs (electronic control units) that work together to boost performance and enhance driving experience.

Components of FLI Power Packages

FLI power packages comprise top-quality custom parts that are manufactured to deliver the desired outcome. FLI has worked for years to perfect its range of parts, and every component is optimized for maximum output. Here are some components of FLI power packages:

Exhaust Systems

Exhaust systems are engineered to increase airflow, reducing backpressure, and deliver an enticing engine note. FLI exhaust systems are made from premium Stainless Steel that ensures durability and maximum performance. The Subaru power packages from FLI incorporate exhaust manifolds, downpipes, and cat-back systems that offer a less restrictive airflow path, allowing the engine to breathe easier and maximize power gains.


FLI offers several turbochargers that cater to different vehicle models and user desires. FLI turbochargers are precision-engineered for maximum performance and flawlessly fit into the existing turbocharger location. The goal is to limit lag time and optimize power production. FLI power packages comprise upgraded turbochargers that operate seamlessly with other components in the system, delivering torque with minimal lag.


FLI intercoolers help maintain low temperatures and boost the engine’s performance. Turbocharged engines generate a lot of heat, and the intercooler helps cool the compressed air before it gets into the engine, purging the engine of hot air and allowing the optimal air-to-fuel mixture for enhanced performance. FLI intercoolers are designed to maximize airflow and efficiency. The company offers several intercoolers that are easy to install and cater to different Subaru models.

Intake Systems

FLI intake systems significantly increase the amount of air flowing into the engine, which promotes power and torque gains. FLI air intake systems are designed to deliver optimal airflow, thanks to high-quality components such as low-restriction air filters and custom heat shields that improve cooling and protect the engine from hot air. These improved airflow conditions are an important part of the equation for optimizing engine performance and delivering a smooth power gain across the powerband.


ECUs are an essential part of a power package. They are designed to communicate with the different parts of the engine and make real-time adjustments for optimized performance. FLI ECUs are engineered to work optimally with the other crucial parts in the power package, ensuring that the engine is running smoothly at all times.
