APR High Pressure Fuel Pump (MS100072) for Audi RS4

If you’re an Audi RS4 owner from 2006 to 2008, you know that performance is everything. The APR High Pressure Fuel Pump (MS100072) is engineered to meet the demanding fueling needs of your 4.2L FSI V8 engine, ensuring you get the most out of every drop of fuel. With APR’s renowned reliability and expertise in high-pressure fueling components, this pump is a must-have for anyone looking to enhance their vehicle's performance.

Why Upgrade to APR's High Pressure Fuel Pump?

APR has been a trusted OEM supplier for VAG since 2006, and their high-pressure fuel pumps have become synonymous with quality and reliability. The technology behind your RS4’s FSI engine allows for direct fuel injection at pressures reaching up to 1,973 psi (136 bar). This is a significant leap from older multi-port injection systems, which typically operated around 40-60 psi. With APR’s pump, you can ensure that your engine is getting the volume of fuel it needs to perform at its best.

Performance Insights

The 4.2L FSI V8 is designed to deliver power efficiently, but as you push for higher performance, the stock fueling system may struggle to keep up. APR's high-pressure fuel pump doesn’t just increase fuel rail pressure; it enhances the overall fuel volume available to your engine. This is crucial if you’ve upgraded to APR’s Stage III+ TVS1740 Supercharger System, which demands more fuel to match its power output.
