Injectors are back. Here is a little word for the wise.....when looking at a set of used 550's everyone says "Pulled from car, worked fine!" That could be true and I'm not trying to say anything bad about anyone, but it should be on YOU to get them tested and cleaned your self. It's only about 100$ and it will save you so much trouble in the long run!
I just got mine back today, they were slightly used and pulled from a working car, they looked great. However, the report said they were 4.7% diffrent before I had them cleaned! Now they are at 1%. Oh, if anyone is wondering where the clips are, these are densos.
