The Stillen 407737B Supercharger Tuned Kit is an exceptional performance upgrade for your Subaru WRX or STI. This kit is meticulously engineered to deliver increased power, torque, and acceleration, transforming your vehicle into a high-performance machine.

The heart of this kit is the Stillen Eaton M45 Supercharger System, which utilizes a compact, efficient design.

The system is also equipped with a high-flow air-to-water intercooler, ensuring that the compressed air is cooled effectively before being delivered to the engine.

The Stillen 407737B Supercharger Tuned Kit also includes a high-performance air intake system, which replaces the stock air filter with a large, high-flow filter element. This allows for more air to be drawn into the engine, resulting in increased power and better throttle response.

Moreover, the kit includes a high-flow fuel pump, which ensures that the engine receives an adequate fuel supply to support the increased power output. This is coupled with a Stillen fuel pressure regulator, which maintains the optimal fuel pressure for optimal engine performance.

The Stillen 407737B Supercharger Tuned Kit is also designed to be easy to install, with clear instructions and all necessary hardware included in the box. The kit also comes with a Stillen calibration chip, which allows for optimal adjustments to the engine's fuel and ignition systems to ensure the best possible performance.

In summary, the Stillen 407737B Supercharger Tuned Kit is a comprehensive performance upgrade for your Subaru WRX or STI. It delivers impressive power gains, improved acceleration, and enhanced engine response, making it an excellent choice for those seeking to take their vehicle to the next level.

Buying a Stilen 407737B supercharged Mazda RX-8 can be an exciting prospect for Mazda enthusiasts looking to enhance the performance of their vehicle. Here are some pros and cons to help you make an informed decision.

1. Increased Power: The Stilen supercharger kit adds approximately 50-70 horsepower and 50-70 lb-ft of torque, resulting in improved acceleration and overall performance.

2. Enhanced Driving Experience: The added power and torque make the Mazda RX-8 more responsive and fun to drive, especially during acceleration.

3. Improved Engine Sound: The supercharger creates a unique engine sound that many enthusiasts find appealing.

4. Increased Top Speed: With the increased power, you can expect a slight improvement in top speed.

5. Better Resale Value: Modifying your car with a reputable aftermarket kit like Stilen's can potentially increase its resale value.

1. Higher Fuel Consumption: Supercharging requires more fuel, so you can expect increased fuel consumption.

2. Higher Maintenance Costs: Superchargers require more maintenance than a naturally aspirated engine. This includes regular oil changes, belt replacements, and potential repairs to the supercharger itself.

3. Reduced Fuel Economy: The added power and the supercharger's parasitic draw on the engine can result in reduced fuel economy.

4. Increased Wear and Tear: The added power and stress on the engine and drivetrain can lead to increased wear and tear over time.

5. Potential Warranty Issues: Modifying your car with aftermarket parts may void your factory warranty.

The Stilen 407737B supercharger kit for the Mazda RX-8 offers significant performance improvements, making it an attractive option for enthusiasts. However, these improvements come at a cost, both in terms of money and maintenance. If you are an enthusiast who values performance over fuel efficiency and is willing to accept the higher maintenance costs, then this kit may be a worthwhile investment. On the other hand, if you prioritize fuel economy, resale value, or low maintenance costs, this kit may not be the best choice for you.

Before making a decision, carefully consider your priorities and budget. If you value performance and are willing to accept the higher maintenance costs and potential warranty issues, then the Stilen 407737B supercharger kit may be a worthwhile investment. However, if you prioritize fuel efficiency, low maintenance costs, or resale value, you may want to consider other modifications or even opting for a different vehicle. Ultimately, the decision is yours to make based on your personal preferences and priorities.
