Deatschwerks Set of 8 550cc Injectors for Audi S4/RS6/S6/S8 4.2L V8 2001-09 (21S-06-0550-8). DeatschWerks pioneered the application specific fitment approach to high-performance fuel injectors in 2005 when “universal” was the standard. This passion for innovation has continued over the years and has culminated in the current line up which represents the most comprehensive and best-supported injector line in the industry. The right tool, used incorrectly, yields substandard results at best. Fuel injectors follow this same universal law. Proper data is required for proper tuning. All DW injectors are fully characterized in-house via SAE J1832 standards. Injector data is available in General Characterization Summaries and Application Specific formats. Using the data is easy. Often it is cut and paste from the DW excel sheet to the tuning software.

Development of accurate injector data is a complex process, but there are no shortcuts to a proper calibration. DW has developed specially designed and calibrated flow benches utilizing digital flow meters, which are required to measure the precise fuel mass needed for proper characterizations. The data acquisition process consists of collecting over 450 data points per injector part number. These data points cover pulse widths, pressures, and voltages that the injectors will experience once installed in your engine. The collected data is statically analyzed, scrubbed and formatted into a General Characterization Summary. This Summary can then be formatted into application-specific formats for different makes, models, and tuning platforms. The application specific data is then in-car optimized by one of our tuning partners. Quality injectors mated to proper calibration data will still perform poorly as a system if the injector set is not properly flow matched. The DW dynamic flow matching process ensures each set works together as a system to fuel your engine properly. Fuel injectors do not operate in a static state so why test them in a static state? In the engine, fuel injectors are a very dynamic component, constantly changing frequencies and pulse widths to precisely deliver the fuel needed.

  • Improves fuel flow and performance

Great but had a problem
It’s great except you have to finagle the darn thing for it to charge. Sometimes I have to use something to get it to lean just right so it charges. Otherwise it’s spectacular and easy to use! Love the foil cutter tbh, that works like a gem!

Nice tool, but with a 4 year life span.
I bought this on Nov. 2020, after hand surgery left me temporarily unable to do simple yet necessary tasks- like opening a wine bottle. 🤪 It's compact, nicely designed, and reliable. I kept it plugged in all the time with no issues. The only negative so far is the blue light which stays on whenever the unit is in the base, fully charged or not. (Not a fan of the many small yet bright lights from all appliances! Placing a Talking Yoda figurine in front of it blocked enough of the light to satisfy me). I found it easy to use and appreciated the foil cutter. Worked well on all types of corks. Flash forward to spring 2024... Despite the constant charging, the corkscrew dies at maybe a half inch into the cork. Just slows down and dies. Having read earlier reviews, I may try to crack it open and replace the battery. But ultimately, having regained my hand strength back, I'm more likely to go back to an old fashioned, reliable, hand operated corkscrew and celebrate the loss of weird lights and needed electricity. Conclusion: unless you are recovering from hand surgery, just get a good quality non- electric corkscrew and use it for 75 years (optimistically). Best deal ever. And you can take it camping too.
