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

2001 Cherokee, the complete opposite of the performance I was looking for. I've heard from others about heat absorption issues, I haven't had this experience with my Cherokee or any other jeep I've worked tuning jeeps on in the last 8 years. Thought a little insurance wouldn't hurt, $70 to protect the fuel from overheating - let's do it! So I bought this kit last spring, installed it at the end of summer, reheated it 4 times since, and in traffic it works like crap. It turns out that the same product retains heat. Wait, it also retains heat. So after wasting $70 and 30 minutes of installation, I need to uninstall this product. It's time to get it right and install a fuel rail that may have a return line to an external fuel filter.
