Overview:

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.

Finally, a Spice Rack That Fixes the Real Problem—Access Without the Hassle
Item Package Quantity: 2
I am pleasantly surprised at how handy this spice rack is!! This iSPECLE pull-out spice rack does that others rarely deliver... makes your daily routine just that much easier. The biggest win here is access. No longer having to rummage through a messy cabinet or knock over jars to retrieve whatever you’re looking for. With everything just sliding out and coming up right in front of you. The idea is simple, but it creates a difference. There's your strong point here: the no-drill, peel-and-stick installation. It’s simple and time-saving, which is something. That being said, it still needs to be installed correctly. Use a clean surface, pressure, and time to set. Do that, and it holds well. Overlook that step, and you’ll be blaming the product when it’s all set up for you. The adjustable height is practical, especially if you’re working with a mix of 4oz and 8oz spice jars. It’s not flashy, but it offers a solution to the same annoying problem: trying to cram mismatched containers into a rigid system. What impresses me the most is that it provides some order rather than making things ever murkier. It’s not looking to reinvent your kitchen. It takes a common frustration (buried spices in dark cabinets) and makes it neat and clean for practicality's sake. Bottom line: If your cabinet seems like a black hole of spices, this is an easy, straightforward solution. Not anything fancy, just smart design and it works!

Be Mindful Of The Height
Item Package Quantity: 2
So this spice rack is amazing, if you know what you're getting. I have had a similar one in the past that was just one level. It was great and made organization easy. This being two levels tall means you have to take that into account because it's going to change the shelve layout in your spice cabinet. It wasn't a problem for me and still ended up being a net positive for making the most out of the space, but my friend bought the same ones and ended up sending them back because they wouldn't fit into his smaller cabinet. If you are aware of that going in and know it's going to work for you, they are amazing. They slide smoothly, they hold a ton, and make getting to the items in the back infinitely better. Decent price for such a huge quality of life improvement for my kitchen.

Didn't entirely save me from the mess, but it got close!
Item Package Quantity: 2, Item Package Quantity: 2
I set these up in my little mini pantry that is admittedly a bit of a mess before AND after, but now it's an organized mess that I can navigate with a bit more ease. It fits well in the space that I have, and the rollers are high quality and feel smooth. If organized chaos speaks to you and you've acknowledged that, this is a great fit!
