{"product_id":"apr-ms100207","title":"APR 17-26 Audi\/Bentley\/Rolls Royce\/Porsche EA839 2.9T\/3.0T High Pressure Fuel Pump (No Rebuild)","description":"\u003cp\u003eThis is accomplished by increasing the bore diameter of the pump's internal pressurizing cylinder. It's important to understand, despite the name, a HPFP upgrade is not necessary designed to increase the engine's fuel rail pressure. The primary goal is to increase the volume of fuel available, which will keep fuel pressure steady even in the most demanding of situations!\u003c\/p\u003e\u003cp\u003eHigh quality components and extreme tolerances:The HPFP internals must be machined to extreme tolerances and installed in a clean environment or the pump can easily fail. Dimensional tolerances on the APR HPFP are as tight as .00004\" and geometric tolerances are as tight as .00005\". The plunger and barrel are created from certified and heat-treated bearing-grade stainless steel and the plunger undergoes a special diamond like coating process for exceptional surfaces hardness and ultra-reliable operation. To prevent float associated with altering the plunger's mass, APR supplies each unit with a properly specified spring. All necessary internal seals are replaced. Internal testing:All APR HPFPs are assembled in house under strict assembly guidelines. Each pump is then tested on our test rig to ensure the pumps operate as designed. This step is important for several reasons. It's critical in determining if a pump has a failure from incorrect install, a leaking seal, or a bad solenoid. Secondly, a seized pump on the vehicle at startup can cause damage to the engine's camshaft. By testing each pump, we all but eliminate these possibility. Proven track record:APR pioneered HPFP upgrades in the early days of VAG direct injection engines. Soon after, APR became an OEM supplier of HPFP and GDI components to VAG for use in various race cars, racing series, project cars, and concept vehicles.\u003c\/p\u003e\u003cp\u003eThe APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 37% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups. This is accomplished by increasing the displacement of the pump using high quality components to exacting tolerances. On the B9 2.9T we achieved an additional 37 AWHP and 50 AWFTLBS over our Stage 1 (E85) ECU Upgrade by adding the pump and running our Stage 1+ (E85) ECU Upgrade!\u003c\/p\u003e\u003cp\u003eHow the direct injection system works:A low pressure fuel pump (LPFP) in the fuel tank delivers fuel to the high pressure fuel pump (HPFP) at roughly 4 to 6 bar. Fuel pressure is then bumped up to a maximum of 200 bar, depending on factory parts, with the HPFP. Finally, high pressure fuel is delivered to the injectors, which spray directly into the cylinders. The problem:The volume of fuel the HPFP pump can displace is directly tied to the displacement of the pump (Internal bore size, and camshaft dictated stroke), and engine speed. The pump is driven off of a lobe on the camshaft. Larger turbocharger systems, and ethanol usage are capable of taxing this system, especially in the mid to lower RPM range where fuel volume is lower. The APR solution:We dramatically increase the volume of fuel the HPFP can displace at every RPM by increasing the displacement of the HPFP.\u003c\/p\u003e\u003cp\u003eThe APR HPFP has been at the center of countless motorsport victories across the globe and has operated with a nearly perfect tract record since the program's motorsport backed inception in 2006. With tens of thousands of pumps sold, APR has a wealth of knowledge, and manufacturing expertise necessary to deliver a product that will and has stood the test of time. OEM Components:Critical to the design of the APR HPFP is the use of only genuine Hitachi components, made in Germany, which consists of sensors, pump bodies, and other critical components that must operate with OEM levels of reliability. All APR components are made in the USA using medical grade precision machinery that goes well beyond the tolerances capabilities found at automotive engineering companies.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDramatically increases the volume of fuel displaced by the HPFP by 37%\u003c\/li\u003e\n\u003cli\u003e+37 AWHP \/ +50 AWFTLS (B9 2.9T E85 Stage 1 vs 1+ with HPFP)\u003c\/li\u003e\n\u003cli\u003eMaintains higher pressures under demanding situations\u003c\/li\u003e\n\u003cli\u003eHeat-treated bearing-grade stainless steel material\u003c\/li\u003e\n\u003cli\u003eFully machine tested and broken in before shipping\u003c\/li\u003e\n\u003cli\u003eIdeal for high output race cars and track use\u003c\/li\u003e\n\u003cli\u003eUpgraded and weight matched spring\u003c\/li\u003e\n\u003cli\u003e.00004\" dimensional tolerances\u003c\/li\u003e\n\u003cli\u003e.00005\" geometrical tolerances\u003c\/li\u003e\n\u003cli\u003eIncludes a new OEM pump\u003c\/li\u003e\n\u003cli\u003eFully rebuilt in house\u003c\/li\u003e\n\u003cli\u003eTitanium retainer\u003c\/li\u003e\n\u003cli\u003eDLC coated piston\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Fitment\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2020-2026 Audi A6 allroad\u003c\/li\u003e\n\u003cli\u003e2019-2025 Audi A6 Quattro\u003c\/li\u003e\n\u003cli\u003e2019-2025 Audi A7 Sportback\u003c\/li\u003e\n\u003cli\u003e2020-2026 Audi A8 Quattro\u003c\/li\u003e\n\u003cli\u003e2020-2021 Audi A8 Quattro\u003c\/li\u003e\n\u003cli\u003e2019-2026 Audi Q7\u003c\/li\u003e\n\u003cli\u003e2019-2026 Audi Q8\u003c\/li\u003e\n\u003cli\u003e2018-2019 Audi RS5\u003c\/li\u003e\n\u003cli\u003e2021-2024 Audi RS5\u003c\/li\u003e\n\u003cli\u003e2019 Audi RS5 Sportback\u003c\/li\u003e\n\u003cli\u003e2021-2025 Audi RS5 Sportback\u003c\/li\u003e\n\u003cli\u003e2019-2025 Audi S4\u003c\/li\u003e\n\u003cli\u003e2018-2025 Audi S4\u003c\/li\u003e\n\u003cli\u003e2019-2024 Audi S5\u003c\/li\u003e\n\u003cli\u003e2018-2024 Audi S5\u003c\/li\u003e\n\u003cli\u003e2020-2025 Audi S5 Sportback\u003c\/li\u003e\n\u003cli\u003e2018-2025 Audi S5 Sportback\u003c\/li\u003e\n\u003cli\u003e2023-2025 Audi S6\u003c\/li\u003e\n\u003cli\u003e2020-2025 Audi S6\u003c\/li\u003e\n\u003cli\u003e2023-2025 Audi S7 Sportback\u003c\/li\u003e\n\u003cli\u003e2020-2025 Audi S7 Sportback\u003c\/li\u003e\n\u003cli\u003e2019-2025 Audi SQ5\u003c\/li\u003e\n\u003cli\u003e2018-2025 Audi SQ5\u003c\/li\u003e\n\u003cli\u003e2021-2025 Audi SQ5 Sportback\u003c\/li\u003e\n\u003cli\u003e2026 Bentley Bentayga\u003c\/li\u003e\n\u003cli\u003e2023-2026 Bentley Bentayga\u003c\/li\u003e\n\u003cli\u003e2020-2026 Bentley Bentayga\u003c\/li\u003e\n\u003cli\u003e2023 Bentley Bentayga\u003c\/li\u003e\n\u003cli\u003e2025 Bentley Bentayga\u003c\/li\u003e\n\u003cli\u003e2023-2025 Bentley Bentayga\u003c\/li\u003e\n\u003cli\u003e2023-2026 Bentley Flying Spur\u003c\/li\u003e\n\u003cli\u003e2022-2026 Bentley Flying Spur\u003c\/li\u003e\n\u003cli\u003e2022 Bentley Flying Spur\u003c\/li\u003e\n\u003cli\u003e2024-2026 Bentley Flying Spur\u003c\/li\u003e\n\u003cli\u003e2019-2023 Porsche Cayenne\u003c\/li\u003e\n\u003cli\u003e2020-2023 Porsche Cayenne\u003c\/li\u003e\n\u003cli\u003e2023 Porsche Cayenne\u003c\/li\u003e\n\u003cli\u003e2022-2023 Porsche Cayenne\u003c\/li\u003e\n\u003cli\u003e2020-2026 Porsche Macan\u003c\/li\u003e\n\u003cli\u003e2022-2026 Porsche Macan\u003c\/li\u003e\n\u003cli\u003e2019-2021 Porsche Macan\u003c\/li\u003e\n\u003cli\u003e2020-2021 Porsche Macan\u003c\/li\u003e\n\u003cli\u003e2021-2023 Porsche Panamera\u003c\/li\u003e\n\u003cli\u003e2017-2019 Porsche Panamera\u003c\/li\u003e\n\u003cli\u003e2020 Porsche Panamera\u003c\/li\u003e\n\u003cli\u003e2018-2023 Porsche Panamera\u003c\/li\u003e\n\u003cli\u003e2022-2023 Porsche Panamera\u003c\/li\u003e\n\u003cli\u003e2018-2019 Porsche Panamera\u003c\/li\u003e\n\u003cli\u003e2017-2023 Porsche Panamera\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003ePlease verify exact fitment (engine, submodel, and trim) before purchasing.\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e MS100207\u003c\/p\u003e\u003cp style=\"color:#666;font-size:0.9em;\"\u003eImages are for illustration purposes only; actual product may vary.\u003c\/p\u003e\u003cp style=\"color:#cc0000;\"\u003e\u003cstrong\u003eEmissions Note:\u003c\/strong\u003e This product is not CARB approved.
