While the system is essentially plug-and-play with the included mounting hardware and wiring harnesses, the factory ECU is incapable of controlling the new setup without significant modification. APR's Calibration Experts spent months fully recalibrating the factory engine management system to operate with both MPI...

The APR Rear Wiper Glass Hole Plug is used to fill the hole when removing the rear wiper. It installs cleanly and flush with the rear window and creates a leak free seal with the included RTV silicone. It's made from CNC-machined billet-aluminum and...

The APR Pendulum mount replaces the factory mount with a new, thick, billet-aluminum two-piece design, featuring a PTFE-lined spherical bearing and ARP® bolts. The system stiffens the driveline to improve shift quality and power transition, while addressing the common and costly factory failure point...

The system provides fine tuning of front-to-back and side-to-side movements to shorten shifts, counterweight...

In addition to the boost tap, APR provides several extra components to help suit each individual's needs. For those requiring more than one reference source, a T-fitting allows for more tapping points. In the case where a mechanical boost gauge is used, the brass...

The APR Oil Catch Can System traps excessive crankcase oil vapors and gunk from entering the engine. The system reduces carbon buildup on intake valves, and octane lowering oil vapors and oil pooling within the intake tract. It's a simple modification to install, drains...

APR's 2-Piece Design Explained: As is true with all machined parts, it's impossible to make all parts the same. In the case of the turbo muffler housing, the distance between the bottom and top of the muffler's housing will vary from turbo to turbo....

Through countless years of professional racing, APR Motorsport identified the factory shifter cable bracket system as a source of sloppy shifts, missed gears, bracket and bushing failure and even transmission failure. The factory shifter cable bracket is made from plastic with rubber bushings. Over...

The factory LPFP sits in a basket submerged in the vehicle's gas tank. The pump operates off of a pulse-width modulated (PWM) signal sent from the pump's control module, which is mapped in the ECU. As fueling demand increases and decrease, the PWM signal...

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...
