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) (MS100207) is the essential fueling upgrade for Audi, Porsche, and Bentley 2.9T & 3.0T EA839 engines, specifically 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 37% over stock.
This increased volume satisfies the stringent fueling requirements of high-horsepower setups and E85 ethanol usage, allowing the engine to maintain steady fuel pressure even in the mid-to-lower RPM range where the stock pump typically struggles. On the B9 2.9T, installing this pump and running the necessary APR Stage 1+ (E85) ECU Upgrade yielded verified gains of an additional 37 AWHP and 50 AWFT-LBS of torque over the standard Stage 1 (E85) tune.
Features:
-
Increased Fuel Volume: Dramatically increases the volume of fuel displaced by the HPFP by 37%.
-
Verified Power Gains: Delivers an increase of +37 AWHP / +50 AWFT-LBS (B9 2.9T E85 Stage 1 vs 1+ with HPFP).
-
Extreme Tolerances: Manufactured in the USA with ultra-high precision, featuring dimensional tolerances as tight as 0.00004" and geometrical tolerances as tight as 0.00005".
-
Superior Construction: Features a DLC (Diamond-Like Carbon) coated piston and a plunger/barrel created from certified, heat-treated bearing-grade stainless steel for exceptional hardness and reliability.
-
Optimized Internals: Includes an upgraded and weight-matched spring with a titanium retainer to prevent float.
-
Quality Assurance: Fully rebuilt in-house, includes a new OEM Hitachi pump body and sensors, and is fully machine tested and broken in before shipping to ensure proper operation.
Product Contains:
-
(1) APR High Pressure Fuel Pump (HPFP) Assembly
-
(1) New OEM Hitachi Pump (Housing/Sensors)
-
(1) Upgraded and Weight Matched Spring / Titanium Retainer
