M brass filter, and all o-rings are replaced with VitonT nitrile rubber o-rings. Every injector is also also pressure tested for leaks, and we include testing documentation with each injector so you can see the test results for yourself.
All our injectors are remanufactured in Eldorado, Illinois, from premium quality OEM injector casings. NOTE: When installing new high performance fuel injectors in your vehicle, you may need to update ECU tuning and/or upgrade other fuel system components. Also, the injectors you receive may not be the same color as those shown in the image. Injectors may also have original markings that do not reflect the actual specs of your injector - be sure to review the included test results if you have questions about flow rate.
