Great Part at a Good Price...
I was hesitant to buy these for our Lincoln Town Car, because of how many horror stories I've read about cheaper aftermarket injectors. However after installation, the car fired right up, smoothed out and ran perfectly. These fit into the ports and fuel rails, just like the originals and seem to operate perfectly. They don't throw any check engine codes and the power output seems pretty much like it was from the factory. The installation of these is also pretty fast and straighforward for our application, and they go in within a couple hours. I can highly recommend these injectors and after a few months, they're still working good...

Great bang for your buck. Work as OEM thus far
Some reviews are trashing on these but for me, so far so good. Don't drive my Vic much, but when i do its sitting at 4k rpm+ doing donuts and these have held up well for that. For the price you cant go wrong. If these fail tomorrow its still cheaper to get another set than an OEM set. O rings match up well and install is easy, just a lot of stuff in the way lol.

Stay with OEM car parts.
BAD decision to go with after-market car parts for this situation. Most times you just have to suck it up and buy OEM parts. Lesson learned. The computer does not like the after-market fuel injectors at all. I don't mean to throw any shade on the Injectors I bought. Again, the car computer is rejecting the part. Car runs really bad until it reaches operating temperature. Bad idea trying to get on an on ramp with it sputtering. Bad when the old injectors going bad are better.

Great value and PRO performance
I replaced my old ones with these on 2004 Lincoln Town car, 4.6L V8 engine. My gas milage went up from 16 mpg to 22mpg Highway instantly. I don't need to press as hard on the gas pedal anymore. It performs like a new engine. Also side note: I replaced spark plugs and coil springs, gas filter at the same time. It has been about a week since I've used it. If anything goes wrong, I'll make sure to update this review. But for now, 5/5 star.
