Deatschwerks injectors. I did have one fail but it was replaced in 2 days under warranty.I recommend both the injectors and the company to all.
But for those who will come across this post in the future while researching injector options, remember exactly what Deatchwerks injectors are. They are "remanufactured" injectors. In this case the remanufacture means cleaned and modified by re-drilling the ports to improve the flow and spray pattern. They are then tested and profiled. At no time are the solenoid windings replaced or re-insulated. When it comes to bang for the buck they are a very good deal and with solid support, very little risk. But you can't expect to pay less than half of what new injectors cost and not have the potential for a few customers to have failures.
