APR High Pressure Fuel Pumps - S5 4.2L V8 (Post Nov 2008)The APR High Pressure Fuel Pump (HPFP) dramatically increases the maximum volume of fuel the HPFP can deliver. In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups.

The APR High Pressure Fuel Pump (HPFP) dramatically increases the maximum volume of fuel the HPFP can deliver. 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.

How 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 136 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 camshaft. Upgraded supercharger and turbocharger systems 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. This 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!

High 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 internal seals are replaced, including the spring seal, and the tip of the pump retains the factory pivoting head to reduce cam follower wear and piston side loading.

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. The 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.

This kit included two new rebuilt pumps.

Best grinders I have ever used
Color: Stainless Steel
I bought these 6 months ago and they are great. They have stopped charging several times. The problem is the salt gets on the contacts and oxidized the contacts and the unit stops charging. You take sand paper and clean the contacts and they work fine again. I feel if the material on the charging port is made with stainless steel and the contacts on the grinders themselves are larger, I would have given this a 5 star. Even As it stands, I would purchase these again. I have several bad experiences buying manual grinders that last about a month and break. These are High Quality, but need to upgrade the contacts.

Salt n peppa
Color: Stainless Steel
Not sure why I waited so long to purchase these! They are great, nice sleek design and they make cooking so much easier! They work so well and I literally just hold it over whatever I’m cooking, press a button and fresh pepper and salt are grinding right before my eyes! In the past my shakers have left salt or pepper on the counter but so far these have not, which is a bonus for sure!

Convenient and sleek
Color: Stainless Steel
These are very easy to use with one-hand operation. The adjustable grind settings work well, and the light feature is actually helpful when cooking. The stainless steel design looks modern on the counter. Grinding power is consistent and strong enough for everyday kitchen use. Pros: • Easy to operate • Adjustable grind size • Attractive design Cons: • Requires batteries • Slightly taller than manual grinders A convenient upgrade from manual mills.

Quiet, Powerful, and Reliable — The Best Grinder Set We’ve Owned
Material Type: Updated-Stainless Steel
After going through several cheaper grinder sets that never held a charge, struggled to grind properly, and eventually broke, I decided to invest in a higher-quality set. This one seemed to check all the boxes — sleek design, convenient charging stand, and an overall premium look — so we decided to give it a try. From the moment we charged them up, filled them with our favorite salt and pepper, and started using them, the difference was night and day. The grind adjustment is impressively versatile, ranging from coarse to very fine, and it’s much easier to adjust than on our old grinders. The charging base uses a USB-C connection, which is a big plus — it works with the same chargers we use for our phones. Aside from the initial charge, we’ve only had to recharge them once in more than six weeks of regular use. The grind quality is excellent, the operation is smooth and quiet, and they don’t sound like they’re straining like our previous sets did. If you’ve been disappointed by cheap electric grinders in the past, do yourself a favor and upgrade to this set. It looks great, performs flawlessly, and is absolutely worth the investment.
