Fuel Injectors For Audi And VW

1. Calibration of the Precision Turbo Engine for Reliable Performance

Our OEM-equivalent fuel injector has a flow rate that is within 2% of what Audi/VW's 2.0T FSI direct injection systems need. This level of accuracy is very important for:

- Stopping lean circumstances from happening in high-boost situations (which are typical in 2012–2014 A6 2.0T CDNC engines)
- Getting rid of reluctance when speeding up at low RPMs (seen in 2009–2013 Golf GTI CAWB engines)
- Keeping the best AFR for turbo spool below 2,000 RPM (tested on Q5 CHJA models)

The 6-hole laser-etched nozzle (with a 0.12mm opening) makes the same 25° spray cone pattern as the original, which guarantees:

30% better fuel atomization than old injectors
Less carbon buildup on intake valves, which is a common problem in A4 CAEB engines
Easier cold starts at temperatures as low as -30°C (tested in the Canadian market on the 2010-2016 A4 Allroad)

2. Design of a self-cleaning nozzle for driving in cities

Our injectors are made for traffic that stops and goes, and they have:

- Anti-coking tungsten carbide tip: This tip doesn't let deposits build while you drive short distances, making it perfect for A3 Quattro city commuters.
- Clearing of deposits automatically when the engine is running at high RPM (above 4,000 RPM)
- Longer service intervals of 60,000 miles compared to 30,000 miles for cheaper options

Results from NYC taxi fleets in the real world (2010–2015 A4 Avant CAEB):

92% drop in CELs associated to carbon (P0172/P0300 codes)
15% better gas mileage when driving in the city

3. Ethanol Fuel Works with New Seals

Our Viton®-lined injector seals offer better protection against:

- Fuel swelling from E15 to E85 (common in Brazilian TT RS conversions)
- Heat damage in places where it's quite hot, such when you're driving with the top down in an A5 Cabriolet
- Additive corrosion from current gasoline with detergent

Proven results in:

E10 mixes from the US Midwest (no seal hardening in 2012–2016 VW Beetle CCTA)
European E5 premium fuels (no leaks in long-term testing of the A6 C7 2.0T)
Flex-fuel conversions (can handle up to E40 without needing to be recalibrated)

4. Installation that really works out of the box

Includes OEM parts for easy replacement:

- Electrical connectors from the factory (no splicing needed)
- Teflon gaskets already in place (no leaks)
- Seating surface that has been precisely machined so that everything lines up perfectly

For anybody who want to do it themselves, here are the installation specs:

Torque values: 8–10 Nm for hold-down bolts (quite important for the 2009–2015 Q5 CDNC)
No coding is needed for vehicles built on the MQB platform in 2012 or later.
30-minute swap time (confirmed in Jetta GLI CCTA workshops)

5. Validation of Military-Grade Quality

Each injector goes through seven tests:

X-ray inspection of solenoid coil welds
Dynamic flow testing with pressure cycles of 1.5, 3.0, and 5.0 bars
Validation of EMI shielding for electronics on the MQB platform
150-bar pressure cycling (which replicates a 10-year service life)
Testing for thermal shock from -40°C to 150°C
Vibration resistance that meets Audi's LV124 requirement
Last bench test with real ECU signals from the 2014 S3 8V
Reliability has been proven in:

High-speed runs on the German autobahn (A6 C7 stayed at 250 km/h)
The heat in the Arizona desert (the 2015 Q5 CHJA fleet had no failures)
Swedish winter weather (starts at -28°C every time)
