ADDED DISPLACEMENT

Your HPFP is an integral part of the B9 3.0T & 2.9T platforms direct injection (DI) system and provides exceptionally high-pressure fuel (exceeding 2900psi) to the injectors. When running turbo upgrades or ethanol fuel, the stock HPFP internal volume becomes the limiting factor when increasing power. IE's HPFP internals install into your factory pump housing and increase the bore and piston size of the pump internals, adding more flow, delivering more fuel, and safely allowing for higher horsepower & torque output.

 

FLOW TESTING

IE HPFP Upgrade Internals offer the largest possible size within the B9 V6 pump body. The factory-installed 9.92mm internal pin has been enlarged to 11.68mm, increasing the stroke volume from 448mm^3 to 621mm^3. The result is a maximum gain of 38.58% more flow over stock!

CUTTING-EDGE RELIABILITY

Every piston and cylinder is CNC machined to exacting sizes, assembled, and measured as a matching set in-house. Tolerances are hand-verified using specialized measurement tools and verified down to 0.00005 of an inch to ensure reliability and proper function. These extreme manufacturing and QC processes have built IE's leading reputation in HPFP reliability and cemented our HPFP designs as the popular choice for those requiring a worry-free operation.

 

PUMP DYNO VERIFICATION

IE HPFP designs are verified and torture-tested on our fuel pump dyno. This machine can replicate countless miles and various RPM situations to substantiate every detail of the HPFP design. This strict engineering process, combined with our 100% in-house CNC machining, obsessed quality control, and top-shelf components, is why IE HPFP Kits have earned their reputation for reliability.

DLC COATED

DLC (diamond-like carbon coating) is an advanced coating process applied to the tool steel pin. This coating reduces friciton by combinig increased hardness with low coefficient properties to providing excellent wear and a self-lubricating behavior that drastically extends pin life.

 

TITANIUM RETAINER

Our ultra-lightweight FEA-optimized titanium retainer reduces the chance of valve float while securing the factory spring to the new IE pump assembly. The internal kit is designed correctly for the factory spring rate, avoiding the need for a stiffer spring that adds unnecessary pressure and wear on the camshaft.

NITRIDED CYLINDER

The HPFP cylinder is tortured with up to10,500 strokes per minute with an extremely narrow tolerance and lubricated solely by fuel. To ensure durability, we have manufactured a tool steel cylinder featuring an advanced nitriding finish. This procedure infuses nitrogen atoms into the material's outer surface, greatly enhancing the surface hardness and wear resistance. Each nitride cylinder is independently verified for thickness and quality in a specialized laboratory.

 

INSTALL TOOL

Disassembly & assembly of the factory HPFP housing requires a specialty tool to thread the assembly housing into the pump body. We have designed and manufactured ours to fit directly to 1/2" drive sockets and torque wrenches. This offers better leverage for unthreading the body and reliable torque spec to complete the installation process without any hassles, making the job easy.

HPFP Socket Tool sold separately

INSTALLATION

Installing your new HPFP kit is straightforward with the correct tools and does not require any permanent modifications. Involves fuel lines and special care to avoid contamination in a clean environment; experienced or professional installation is highly recommended.

Install time around 2-3 hours

  • How do I know if you have an item in stock?

    In-Stock Products

    In Stock

    Items marked as "In Stock" are physically in our facility, so they're ready to ship when the order is placed. If all items in your order are "In Stock", then your order typically ships within one business day.

    Other Availability Modes

    We use several availability modes to most accurately identify when products will leave their home facility:

    Direct Ship This product is available and will be sourced from one of our suppliers. It may take up to three business days before it ships.

  • How do I know if a part will fit my car?

    We update our catalog daily to provide the most accurate fitment information possible. When shopping for parts, please use the “select your vehicle” car selector on the home page. Once you've selected your car, you can filter parts specific to it.

    Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.

    Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".

  • What is a core charge?

    A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.

  • What is MAP pricing? Why can't I get a discount on a MAP item?

    "MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
