I am about to install a set of 6 new Niehoff (57512) 420cc fuel injectors but have a concern that they may need to be flow tested first. There are some variations in the Niehoff's such as different packaging, lack of hose clamps in some boxes and different stamping numbers. If they can't be consistent about packaging and including hose clamps, can I trust that they can put together a fuel injector?
So, should I get these brand new injectors flow tested or is it your experience that quality control is usually pretty good and shouldn't be a cause for concern?
Has anyone used these Niehoff injectors on their Z?
If it matters, I also have 2 new Beck Arnley (158-0438) 420cc's and they look pretty much identical to the Niehoff's.
