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

Definitely works!
I noticed I was having weird rough patches on my back and thighs but didn't know what they were. So with my next appt to the dermatologist, I found out it was eczema. Ugh. So I started looking at creams and such and stumbled on this bar soap. It works really well. When I shower, I work it into the problem areas and let it sit there with the shower head turned away so it doesn't wash off, and then wash my face, etc. When I'm finished with everything, I wash everything off, after the soap has been on my skin for several minutes. I've noticed a substantial decrease in the bumpy areas on my back and legs. I loooove this soap, and yes, definitely recommend it for people dealing with eczema. But definitely use an exzema skin cream too if you are itching. I wasnt, but started to as well because it also helps to keep the outbreak under control as well.

Soap for dry skin on the face and body
This soap does soften the skin of the affected area but the itching still continues. I am not sure if there is an anti itch ingredient in the soap but there should be.

Great sunscreen!
Style: 4 Fl Oz (Pack of 1)
Eucerin Sunscreen works well and applies cleanly, not greasy. I spend a lot off time outdoors and I am satisfied with the sun protection this product provides.

Don’t rub, break it down between your fingers and dab!!
Style: 4 Fl Oz (Pack of 1)
Great sunscreen. The first time I applied it, i made the mistake of rubbing it in so it gave me a white cast. I learned my mistake the second time, spreading it in between my fingers and than dabbing it on my face, it gives a cast at first but after a few minutes it went away. And it feels so good. like I’m not wearing anything. I tried the tinted sunscreen it feels good but it made me look orange. I used to wear the Eucerin Daily Lotion spf 30 but they discontinued so I had to look for a replacement and after trying other sunscreens they were all terrible; greasy, allergic reactions and too creamy! This one’s perfect, it’s definitely my new go to!!

The Only SPF My Skin Will Tolerate!
Style: 4 Fl Oz (Pack of 1)
After 20 rounds of radiation, I was given a list of exactly four things I could put on my face--things like water and Vaseline. Of course, I was also instructed to wear SPF in "all visible light." However, finding a sunscreen my skin could tolerate proved to be a challenge, as even those made with clean ingredients, marketed for babies, and/ or claiming to be hypoallergenic resulted in hot, angry rashes. Price point also didn't matter; I tried everything from drugstore to premium brands.
Thankfully, when this product came on the market, my dermatologist suggested I try it. I've been wearing it ever since. It IS thick so I usually rub any remaining face moisturizer into my palms and then add the Sunscreen, rubbing and warming it between my palms to make it more easily spreadable. Then I press it onto the skin on my face with my palms and fingers--I don't like to pull or tug too much at the skin on my face. At first, there is a visible white cast, but it disappears within a couple of minutes.
If I'm really in a hurry, now I can mix a tiny bit of my foundation into the sunscreen so that it spreads faster and I can move on from the white cast faster--I know I lose some sun protection factor that way, but my derm says I also gain some protection in the tinting, so it's okay. The important thing is that I get it on in whatever time I have.
I'm just grateful to have found something that doesn't upset my crazy-sensitive skin! Wishing all you sensitive beauties protected fun in the sun...
