Stainless Steel Injector Bodies a Myth? Are you really getting New or Remans?

[BrianAtSmarty]

There is a common misconception that there are Bosch injector bodies available for the CR Cummins application made out of stainless steel. That is a myth. None of the Bosch injectors for this application are made of stainless steel. BBi INJECTOR Bodies have been offered in two different versions. The original body “look” of Big Bang Injectors had a darker exterior. Now they have a shinier look to them. Some say that they, along with injectors from elsewhere, are Stainless Steel. Fact is they are not made of Stainless Steel. The only difference between the first BBi Injectors and the new appearing Injectors is the coating that is used to prevent corrosion. They both have the the exact same body material. The darker bodies are Phosphated. The new lighter colored bodies are Silanized. Why the change? Well the coating has been changed to gain a bit better resistance to corrosion that you would get with the Silanized surface coating. This practice was brought about for engines with external injectors. This would have no effect on the Cummins engine whatsoever. The belief that these are Stainless Steel injectors for the common rail Cummins is a myth.



Also a lot of people getting injectors are under the impression that they are getting “New” injectors when in reality they are getting remanufactured injectors. Here is a FYI for you. Bosch remanned injector part #'s start with a 0986. New injectors start with 0445.



A lot of remans are being marketed as new injectors. True "NEW" injectors are scarce these days.

Thanks for the info!

Brian - - - Thanks for the info - - -sometimes hard to separate the truth from the fiction around here!

When the new injector bodies came out, we were told they were stainless. Later we found that they had a "saleen" coating with I guess is another *******ization of silanized coating by non-chemists. Whatever, it seems that raising rail pressure is hard on the injectors, and Smarty has recommended not doing that for normal usage, although the program has that option. Brian, I assume that is still the case.

Thank you Gentlemen!

Yes Sir Joe, the race programs TNT-r and the SSR tuner have the option to give more rail pressure than stock. The S-06 standard REVO tunes do not give more pressure than stock. It just ramps up the RP quicker. That is adjustable on the standard S-06 programing however so the pressure comes in even sooner on setting 3, and setting 4. It is suggested to use setting 2 (default) on rail pressure (or setting 1) (stock) for daily driving. Excess pressure over a long duration, or ramping up to max stock pressures is still unhealthy for CR injectors.
Rail Pressure
The Rail Pressure selection can be programmed 1 (stock), 2 (mild), 3 (moderate) or 4 (wild).

Thank you!
