Injector reference for the shared VAG V10 platform: Gallardo, Huracan, and both generations of Audi R8, including the 4.2 FSI V8. OEM part numbers, the Gen 1 versus Gen 2 dual injection story, and why a 200 bar FSI system needs a bench that can actually test it. Compiled by the injector cleaning department at Boost Lab, Inc.
Every injected engine in this family is a Volkswagen Group design, and the injectors carry Audi part numbers. The 5.2 FSI V10 direct injectors in a Gallardo LP560, a Gen 1 R8 V10, and a Huracan all come from the same 07L906036 family, with suffix revisions over the years and 07L906036M as the current version. The R8 V8 shares its 079906036 family injectors with the 4.2 FSI in the RS4. That matters for your wallet: injector diagnosis and service on these cars is specialist work, but it is not unobtanium exotic parts work, and cleaning and flow verifying a set of ten is a fraction of what a dealer will quote to replace them.
The FSI system itself is serious hardware: two cam driven high pressure pumps feeding two stainless rails at pressures up to 200 bar, with a solenoid direct injector seated in each combustion chamber. Testing these injectors at port injection pressure tells you almost nothing. Our Carbon Zapp GDI bench tests at true direct injection pressures up to 300 bar with flow and leak documentation per injector, which is exactly what a ten cylinder engine with a misfire count needs.
Gen 1 and Gen 2 are different service stories. The first generation 5.2 FSI (Gallardo LP550 through LP570, Gen 1 R8 V10) is direct injection only, which means classic DI problems: carbon accumulation on the intake valves and injector tips that foul with heat soaked deposits. From the 2015 Huracan and 2017 Gen 2 R8 onward, the engine runs dual injection: ten MPI port injectors handle low load, the FSI system takes roughly 85 percent of the work at full load, and the port injectors continuously wash the intake valves. Twenty injectors per car, two different technologies, and both sets age.
| Application | Years | System | OEM / Ref PN | Notes |
|---|---|---|---|---|
| Gallardo 5.0 V10 | 2003-08 | Port EFI | Bench data on request | First generation engine, conventional port injectors |
| Gallardo LP550 / LP560 / LP570 | 2008-13 | 5.2 FSI direct injection | 07L906036 family | DI only, carbon prone generation |
| Audi R8 V8 4.2 FSI | 2008-15 | FSI direct injection | 079906036AA, 079906036C | Shared with B7 RS4, Hitachi FIJ0038 cross |
| Audi R8 V10 Gen 1 | 2009-15 | 5.2 FSI direct injection | 07L906036 family | Same engine family as Gallardo LP560 |
| 2015 and later 5.2 V10 engines run dual injection: ten FSI direct injectors plus ten MPI port injectors per car. Both sets are serviceable and both sets matter. | ||||
| Huracan LP580 / LP610 / Evo / Performante / STO | 2015 on | FSI direct, dual injection | 07L906036G / J / K / M | 07L906036M is the current revision |
| Audi R8 Gen 2 (incl. Plus, Performance) | 2017-23 | FSI direct, dual injection | 07L906036G / J / K / M | Same injectors as Huracan |
| Huracan / R8 Gen 2 MPI side | 2015 on | Port injection | Bench data on request | Low load duty, valve cleaning function |
| Injector Dynamics ID1050-XDS | Huracan / R8 Gen 2 | MPI upgrade, set of 10 | 1050.34.14.14.10 | 1065 cc at 3 bar, 14mm grey adapter top, common on turbo builds |
A misfire code on cylinder seven does not have to mean ten new injectors at exotic dealer pricing. We test the full set at pressure, identify the weak units in numbers, and clean and verify the rest. The report tells you exactly what to replace, which is usually far less than everything.
DI only Gallardos and Gen 1 R8s foul injector tips and carbon their intake valves by design. Heat soaked deposits shift spray patterns and lean individual cylinders. Ultrasonic cleaning plus high pressure verification restores the set and documents it.
Twin turbo V10s lean hard on the MPI side, and ID1050-XDS sets are the standard upgrade. As an authorized Injector Dynamics dealer we supply them, and every set we sell or service can be flow verified and documented before it goes in the car.
For the injected V10 family, yes. Gallardo, Huracan, and R8 direct injectors come from the Audi 07L906036 part family, and the R8 V8 shares its 079906036 injectors with the RS4. You are paying for a VAG part and specialist knowledge, not an exotic unobtainable component, and that is exactly why cleaning and flow verification is such a strong alternative to dealer replacement.
The first generation 5.2 FSI is direct injection only, so carbon accumulates on the intake valves and heat soaked deposits foul the injector tips. Fouled DI injectors shift their spray pattern and flow, which shows up as cold start misfires, rough idle, and single cylinder misfire counts. High pressure flow testing identifies the actual offenders before you start replacing parts.
Yes. The factory FSI system runs up to 200 bar, and our Carbon Zapp GDI bench tests at true direct injection pressures up to 300 bar with per injector flow and leak documentation. A port pressure test on these injectors is not meaningful, which is why most shops cannot honestly evaluate them.
From 2015, the 5.2 V10 runs dual injection: ten MPI port injectors handle low load running and continuously wash the intake valves, while the FSI direct system takes roughly 85 percent of the fueling at full load. It was added largely to solve the Gen 1 carbon problem. Both sets age in different ways, and a complete service addresses both.
Yes. We are an authorized Injector Dynamics and Fuel Injector Clinic dealer, and the ID1050-XDS set of ten is the standard MPI side upgrade for turbocharged Huracan and Gen 2 R8 builds. Any set we supply or service can be flow verified with documentation before installation, so your tuner starts from known numbers.
