Siemens Deka 630cc Injectors x6
Genuine Siemens Deka injectors, including tuning data
Not much to be said - These are genuine Siemens Deka injectors ready to be fitted to your M50, M52, M52TU or M54 intake manifold and fuel rail. Each set purchased through us will have the tuning data available. When deciding on injector size on our 6-cylinder engines, think of 1cc as roughly 1hp (for petrol/gasoline). The larger the injector size, the more fuel that is released into the intake port in the same amount of time.
Arguably one of the most important parts of a reliable turbo build are the injectors. Many tuners will refuse to map a car with cheap or unknown injectors as they cause so many headaches. Knock-offs are available all over the internet but often stick open or closed soon after fitment, causing misfires and/or detonation - they are cheaper for a reason. By spending more money on a reliable set first you will save yourself trouble further down the line.

On an M50/M52 manifold, the Standard length injectors are a straight swap.
On an M52TU/M54 manifold, the Standard length injectors require a spacer to be added underneath the fuel rail. They are approximately 10mm taller than the standard units. We suggest buying spacers of the correct height or using a standard height M8 nut underneath the base of the fuel rail to make up the difference.
