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.
INCLUDED LIMITED WARRANTY
Due to the extreme machining and coating tolerances, Integrated Engineering is proud to offer a limited warranty on this product:
Unlimited miles for six months from the day of purchase
DLC COATED
DLC (diamond-like carbon coating) is an advanced coating process applied to the tool steel pin. This coating reduces friction by combining increased hardness with low coefficient properties to providing excellent wear and a self-lubricating behaviour 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

amazing
Format: Kindle
Knot the Bride was a fantastic read! The characters were all amazing and well-developed. It was easy to like them all. Sophia, Luca, Nick, and Gavin were all perfect for each other. It was such a charming story that had me hooked the entire time. I did wish there were POVs from Luca, Nick, and Gavin but it was still an amazing book without it.
I am excited to read the next book in the Willowside Omegaverse series! This is definitely a must-read for fans of omegaverse romance!.
I received a free copy of this book and am voluntarily leaving a review.

3 Star Read,
Format: Kindle
This book wasn't bad, but wasn't my cup of tea. It's highly disappointing because the storyline is so original. There is no real conflict or resolution, so the entire thing feels flat.
As a lover of omegaverse books, I know there is a ton of variety out there, and ov is really up to the author. But this one is weird. Omegas have multiple scent glands all over their bodies and go into week long heats every month. Alphas have knots in the middle of their shaft instead of the base, and the knot doesn't always swell, no explanation of when or why. It doesn't engage at all when the mouth is in play.
I also didn't enjoy the author's writing style. Each paragraph is only 1 or 2 sentences long, and the entire book reads very stacato. The conversations are stiff and unnatural feeling. Everything is very repetitive, both in word choice and in thought. The same thing is repeated 3 or 4 times over a single page, multiple times over. I ended up doing so much skimming.
The first 50% of the book is all slow burn, and the last 50% is almost straight mediocre spice. This wouldn't have been all bad if the grammar and spelling errors didn't start at the exact same time. Tongue is repeatedly misspelled in the middle of the spice.

Cozy Omegaverse
Format: Kindle
This is the true definition of Cozy Omegaverse. LA wedding coordinator meets her pack at the location for a couple’s destination wedding. Low angst because they are scent matched high heat with heats and knots. Everything you love about this genre with very little anxiety. Simply a fun experience to read and a book I will comeback to when I’m in a slump. I simply love reading this book

Cute Omegaverse story
Format: Kindle
3.75 stars and 2 for spice. Adorable Omegaverse story about a wedding planner who has to go to a small town to plan a wedding for a movie star. While there, she meets her pack. This covers her struggles of not living there but trying to keep her relationship going with her 3 Alphas.
It's a quick read and cute, so I recommend it for people who like light-hearted RH stories.

real good
Format: Kindle
This was a solid read for the ABO universe. The characters are great. The smut scenes were well written. And the town is so cute I want to go there. It didn’t have much character development it just felt like I was getting to the characters as they were getting to know each other.
