APR High Pressure Fuel Pumps: The Ultimate Upgrade for S5 4.2L V8 (Pre Nov 2008)

The APR High Pressure Fuel Pumps are engineered to revolutionize the performance of your S5 4.2L V8 (Pre Nov 2008) by delivering a dramatic increase in fuel volume. These high-performance pumps are designed to cater to the needs of high horsepower setups, ensuring your engine receives the fuel it demands. With a focus on precision engineering, these pumps offer an impressive boost in displacement, thanks to their high-quality components and exacting tolerances.

• Increased Fuel Volume: Accommodate high horsepower setups with a substantial increase in fuel delivery capacity.
• High-Quality Components: Crafted with precision to exact tolerances, ensuring optimal performance and reliability.

Understanding the Direct Injection System

The direct injection system relies on a low pressure fuel pump (LPFP) to deliver fuel at roughly 4 to 6 bar to the high pressure fuel pump (HPFP). The HPFP then boosts this pressure to a maximum of 136 bar, ensuring high pressure fuel is delivered to the injectors for direct cylinder injection. However, the standard HPFP may struggle to meet these demands, especially with upgraded supercharger and turbocharger systems.

• Enhanced Fuel Pressure: Maximum pressure of 136 bar ensures optimal combustion and performance.
• Engine Compatibility: Designed to work seamlessly with upgraded supercharger and turbocharger systems.
