HIGH-VOLUME INTERNALS
Your HPFP provides extremely high fuel pressure (exceeding 1500psi) to the direct injection system on your Audi 3.0T supercharged engine. Fuel output and ultimately power is limited by the internal displacement of the pump. By increasing the bore and piston size of the pump internals, the HPFP upgrade is capable of producing much more flow. This higher-output HPFP design offers the fuel increase needed for those running Stage 2 Dual Pulley setups and looking to run higher octane fuels for aggressive race and track style driving.
PRECISION ASSEMBLY
The internal assembly of your HPFP is a delicate balance of astonishingly high pressure and extremely delicate tolerances. Every piston and cylinder is a match set CNC machined to exacting sizes. Tolerances between the two are hand-tested using precise measurement gauge tools and verified down to 0.00005 of an inch! These tolerances are required due to the maximized size of our pump assembly and absolutely critical for HPFP reliability and function. Even the smallest contamination can cause pump wear or failure, to ensure this each pump is assembled in a clean environment with a Laminar flow hood. This is why IE only sells HPFP pumps fully assembled in new OE housings as to ensure reliability.
Engineered & manufactured in the USA
INCLUDED LIMITED WARRANTY
The IE HPFP upgrade internals allow for the largest displacement available. To accomplish this, the assembly tolerances are incredibly tight and proper installation in a clean environment is absolutely critical. Due the required specialized equipment to assemble, test, and verify our IE HPFPs they are only sold as complete assembled units in new Audi OE housings. Due to this in-house assembly process, IE offers a Limited Warranty on the entire pump assembly:
Unlimited miles within 18 months from the original purchase date
CONSTANT DIAMETER PIN
The piston & cylinder engineered for HPFP upgrade is a constant diameter design; meaning it maintains the outer size through the entire piston shaft. This ensures no displacement change occurs on the bottom side of the piston and protects against pressurized pulses against the shaft seal. After testing many pump designs, IE engineers determined this feature necessary for long reliable pump operation. Be wary of pump designs with a stepped diameter engineered to use the factory seal as a cost saving design. We have found these units reduce the contact between the pin and cylinder by over 50% which greatly increases wear, pin leakage, and instability of the pin.
DLC COATED
DLC (diamond-like carbon coating) combines hardness and low friction, providing excellent wear properties and self-lubrication behavior that drastically extends the life of the tool steel piston.
NITRIDED CYLINDER
The cylinder can see up to 19000 strokes a minute and is lubricated by fuel only. Our tool steel cylinder is infused with nitrogen atoms into the atomic structure of the outer surface of the component, increasing surface hardness and wear properties drastically. The thickness and quality of every nitride production batch are independently verified in a specialty lab.
LEAK-FREE SEAL
To prevent fuel leaking past the HPFP seal and into the crankcase, our HPFP upgrade includes a molybdenum disulphide seal used for it's stiffness and reduced friction characteristics. To further reduce the chance of failure, the seal is spring energized to provide constant outward pressure, even as the seal ages. What may seem like a small feature -in reality provides a reliable and long-life HPFP upgrade.
PUMP DYNO BREAK-IN
Every IE internal kit is run on our own application-specific fuel pump dyno to verify proper function and break-in before being packaging. This strict QC process, combined with our 100% in-house CNC machining and top-shelf components, is why IE HPFPs have earned their rock-solid reputation for extreme reliability.
INSTALLATION
Installing this fully assembled pump is a fast and easy same as stock bolt-in upgrade. Installing your new HPFP involves disconnecting fuel lines and experienced or professional installation is highly recommended.

2016-2017 A6 & A7 CREC 3.0T engines are equipped with both direct injeciton (DI) and manifold injection (MPI) and do not require HPFP upgrades for ethanol use. Compatible IE software tuning is not available for HPFP use on CREC engines. CREC engine is also found in ROW (rest-of-world) markets on some late-model S4 & S5 3.0T as well. CREC engines are easily identified as the supercharger pulley has 4 bolts to attach it to the supercharger instead of a press-fit style.

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned.
These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.

The dogs like it very much, it produces a lot of noise.
Size: Large, Size: Large
I’m rating this based on my dogs’ response to this toy – they absolutely love it, and it has seen more use without damage than any of their regular throwing toys. At the same time, unless you enjoy, REALLY ENJOY the sound of crunching water bottles, you may not like having this ball in the house.
Pros:
The rubber outer shell of the ball is durable, and can survive both chewing and pulling forces (as a note, my dogs do not concentrate on chewing - they use it more for play games). It’s big enough for my dogs to play tug of war with it, hooking their teeth in the mesh, and they since it bounces around if they drop or kick it, it makes the game more interesting than rope. They did crush the interior plastic, but they don't really seem to care.
It’s much more engaging than a normal ball, and can be modified to hold treats, sticks, rope elements and other external bits, which my shepherd mix loves; he gets bored easily and frequently, and this can actually entertain him.
Cons:
This toy is loud, and produces repetitive crunching sounds. It is apparently really engaging to chew, and my dogs will produce the horrid plastic crackling up to half an hour at a time. If you let your dogs in and out, it would make a fine outdoor toy, but since I have a dog door, it migrates around to pretty much wherever the dogs are. I kind of hate it, but will probably buy another if they break this one since they enjoy it so much.
