This low price is for a set of eight professionally refurbished and fully tested GM Chevrolet OEM Delphi fuel injectors, # 25317628, or for cross reference purposes, SMP # FJ315.
This is a Flow Matched Set.
Beware of buying a cheapo set of aftermarket ' no name ' brand of fuel injectors !! There are a few look a-likes for sale online that are not OEM, and are definitely not OEM quality.
The cheapo knockoff injectors are junk. When I get the knockoff's in my shop as core returns, I just throw them out in the garbage. Their flow rates are all over the place, and are inconsistent.
The eight cylinders of the fuel injector bench testing unit in the picture above are the actual flow test results from this set of Delphi injectors - after servicing, this set performed excellent, and flow matched at 2 % (Awesome) !!!! A flow matching set of injectors should all be flowing within 5% of each other for proper engine performance, power, smooth idling and smooth throttle response during acceleration.
These injectors performed flawlessly during all the performance tests in the computerized fuel injector bench testing unit.
These injectors have all new upper and lower o-rings, and more importantly, all new internal microfilters have been installed. Why take a chance on buying untested used fuel injectors that may have crud filled internal filters, old hardened o-rings ( vacuum leaks, fuel leaks ), or a bad coil ??
These injectors look good, and show some normal cosmetic signs of being in prior service ( light stains, scratches, nicks etc.).
All of the injectors I sell are fully cleaned, back-flushed, lubricated, and flow tested. They are 100% ready to be put into service.
They are guaranteed to perform like new.
Outside of ebay I run a Fuel Injection Refurbishing business called Injector Repair LLC. Either getting your own vehicles' injectors refurbished, or buying a complete set of flow matched refurbished fuel injectors is a great way to save a ton of money vs. buying brand new injectors at $70 TO $150 FOR EACH NEW INJECTOR. Genuine OEM Fuel Injectors are designed to outlast your engine, and should last way more than 300,000 to 500,000 miles. They usually only fail to perform when they get clogged ( a bad side effect of ethanol, or a bad batch of contaminated gas ), or when the injectors internal coil winding fails ( happens, but rarely ). Genuine OEM injectors that are factory original are far superior in quality than the aftermarket injectors sold by the big name aftermarket suppliers. They may look the same, but they are definitely not the same quality as OE brands like Bosch, Delphi, Denso, IPT, JECS, Keihin, Magneti Marelli, Nikki, Rochester, Siemens Deka, and Weber.
Each fuel injector is;
- externally cleaned
- resistance checked
- parts ( including internal filter ) are removed
- clogged injectors are ultrasonically cleaned while being computer driven
- injectors are back-flushed
- Then the injectors parts are replaced with new high quality o-rings, plastic caps ( when needed ), plastic spacers, and with new internal injector microfilters.
- The injectors are then flow tested on a computerized fuel injector bench testing unit and evaluated for leak down, flow volume and spray pattern. In order to pass, the injectors have to not leak when closed under full pressure, and they have to have the proper spray pattern and the proper flow volume when tested under a number of different scenarios. They are subjected to multiple tests and are tested; At Static condition (wide Open), 3 millisecond pulse width, 6 millisecond pulse width, 12 millisecond pulse width, and are tested at various RPM.'s. These tests insure that the injectors are performing correctly under all conditions, and will detect a faulty injector coil that may have passed a resistance check.
