Review on 🚙 Jeep Fuel Rail and Injector Cover Kit (1997-2004, 4.0L Engine) by Design Engineering 010378 by Andres Callahan

Installed on a 1999 XJ. The heat shield that sits on top of the manifold is better than the factory one. The fuel rail wrap is tight and well made, with one exception - it doesn't account for the fuel pressure regulator (1.75" washer about halfway down the rail) so you'll have to cut the mark in the braid with a sharp blade. . I also took the opportunity to remove the label. Finally, the nozzle shrouds are cut into rectangles, which does not result in a perfect fit around the individual nozzles. The cone shape of the coffee filter works better and allows for pigtail connections. However, you have enough space for it to work. I did this in combination with an injector swap (avoiding the neon 4 holes for better throttle response) and ended up being very happy with the results. A little extra engineering in the production would have taken a long time, but it's still a great product and I'm glad they make it. Hopefully it will hold up and a little trimming won't cause the packaging to loosen itself. I definitely recommend it. Even with modifications. Take your time and the installation will go smoothly.
