Please Be Aware of Fake Siemens Deka 630cc / 60lb Injectors ( FI114961 ) & ( # 39-041)

2026 update: The # 39-041 is the updated part number that supersedes the original Siemens Deka 114961, featuring the same reliable fit and performance characteristics.  btw there are no longer DEKA stamps on injectors anymore. Just part number #39-041, serial number & QR code.

I’ve made this step-by-step guide with some photos provided to help you identify fake Siemens Deka 630cc fuel injectors. Recently there’s been a big increase in counterfeit Siemens Deka 630ccm FI114961  and Siemens Deka 875cc FI114992 performance fuel injectors appearing on the market which are made in China. Please don’t be fooled, even with “Deka” stamping on the fuel injectors.

Fake injectors will have issues ranging from lo fuel supply to misfiring which will result in engine running problems.

This quick guide below show what a real Siemens injector and a fake one look like side by side as it can be difficult to tell the real one apart.

In these images the genuine injector is on the left side so you can compare both and know which fuel injectors are fake.

These are now being sold in Germany, Austria, Netherlands, UK and all Europe Countries. Price of these FAKE injectors should be a give away, but when these fall into the hands of dishonest sellers it becomes more difficult to tell. Authentic Siemens Deka 630ccm should be no less than €65 and Siemens Deka 875ccm no less than €70
