WARNING: This product can expose you to chemicals that are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, visit www.P65warnings.ca.gov.The APR High Pressure Fuel Pump (HPFP) (MS100061) is the essential fueling upgrade for the Audi TT RS (8S) 2.5TFSI engine, designed to eliminate the common bottleneck in the direct injection system under high-demand scenarios. By increasing the internal displacement, the APR HPFP dramatically increases the maximum volume of fuel delivered by 30% over stock.
This increased fuel volume is crucial for satisfying the stringent fueling requirements of high-horsepower setups and maintaining steady fuel pressure, even when the factory turbocharger or larger turbo systems begin to tax the fuel system at lower RPMs. The pump uses high-quality, extreme-tolerance components, continuing APR's proven track record as a pioneer and OEM supplier of GDI components for VAG vehicles since 2006.
