Finally got a chance to install these injectors about 2 weeks ago. They came well packaged and looked identical to the OEM injectors in my challenger, but after install by a certified mechanic, they were exhibiting wierd issues, specifically on cold start. Once the engine was warm, they worked ok, but there's something about the cold starts they don't like. He reset the computer a couple times and after about a week of use, the Check Engline light started coming on, so I asked him to put the OEM injectors back in and all of the issues went away. Just to note, they fit like factory, and looked like factory, but either I had a bad injector in the bunch or they aren't 100% compatible. Had they worked as I'd hoped, they definately would have been a good value for the price, as OEM injectors are way overpriced in my opinion.

Very prompt delivery. Very good product

The advertisement states upgraded fuel injectors but after the initial install I am not able to tell a difference. The seem to function just like the original which is a good thing just not sure I would call it an upgrade. The installation is pretty basic if you are familiar with doing that type of work. The fit just like the original too so overall they are off to a good start. As long as they last then I will be happy and they will justify the price. However so far so good as we are off to a good start.
