Used set of injectors from an TPI1 engine.  These are aftermarket injectors, more than likely 30# Accel or Ford Motorsport, but no guarantee as there are no PN's on the injectors.  These injectors have been sitting on the shelf for 5+ years, and are sold as non-working cores. These should be tested and cleaned before use.  Sold as a set of 8. 

The item in the photo is the exact item being sold.
