High horsepower configurations often require more fuel, especially on applications where ethanol is used. The APR 980cc MPI Injector Upgrade Kit includes an upgraded high-flow multiport injection (MPI) injector and harness necessary to satisfy high horsepower builds. The kit uses a compact and extended tip Bosch EV 14 injector that supports Ethanol and Methanol and flows 980cc/min at 3 bar. A high quality 2 wire harness with braided wire sheathing converts the Bosch Jetronic connector to the necessary factory style connector making this upgrade plug-and-play with an associated ECU upgrade.

The APR Axleback Exhaust (Valveless) Conversion is a direct bolt-on to an existing APR Catback Exhaust System and converts your valved with mufflers system to the APR Valveless System.

APR Direct Replacement Brake Discs are a plug-and-play upgrade for your factory brakes. They provide reduced brake fade, improved brake consistency, and excellent modulation, especially during repeated consecutive braking applications or spirited driving. The rotors have improved resistance to distortion, warping, and cracking at high temperatures. They pair perfectly with the APR Direct Replacement Advanced Street Pads and provide a no-compromise solution for spirited daily driving.

This compound is specifically aimed at advanced track day users and offers full race performance under track conditions. While it can be used to drive to and from the track, some brake squeal will be experienced during street driving. It is not recommended that this pad material be used for extended daily street use as accelerated disc wear and brake noise will be experienced during daily street driving. On track this compound will offer unmatched brake performance and fade resistance and will be a significant step up over our Advanced Street / Entry-level Track Day compound. The material remains kind to discs under track conditions and pad wear is low. It has a slightly rising torque curve and modulation remains excellent. A mechanical retention system is employed between the pad backing plate and the friction material for maximum shear resistance during high-temperature use. Advanced track day users will really appreciate the characteristics, performance and wear life that this compound offers. For advanced track day customers that also use their car as a daily driver we suggest a two-pad strategy in which you run our High-Performance Street compound for daily street use and then switch to our Advanced Track Day material for track events.

The APR Steering Wheel is beautiful, functional, and convenient to purchase. The top and bottom sections feature a carbon fiber weave, and the sides are motorsport inspired perforate leather with color matched stitching. The deep pocketed palm and thumb grooves on the sides give you a confidence-inspiring grip, and feel comfortable in your hands, as do the ergonomically shaped finger grooves at the top rear of the wheel. Beautifully cross stitched threads give the leather section an extra elegant touch that matches your interior’s stitching. And lastly, the flat bottom gives you extra room for your legs, while also letting you know if the wheel is straight or not when tracking the car. Simply put, we’ve made personalizing your steering wheel easy. This is our own design. We don’t modify or wrap your existing wheel. We ship you a new wheel and you swap over your factory controls and airbag. There’s no months of downtime without your car to ship out and modify your existing wheel, and there are no core fees. Simply swap, install, and enjoy!

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.
