Review on High-Quality Fuel Injectors (6Pcs) for Jeep Cherokee, Grand Cherokee, Wrangler & Dodge Ram 4.0L/5.2L - Replace OEM #s 0280155784, 4854181, 280155784, 4667938 by Anil Jaimes

So far I'm happy with these nozzles. I modified the head to match the headers, added an aftermarket cold air intake, a 2.75" exhaust all the way back, and a new set of caps. Rotor connector and cable. There was one very clear difference. Consistent power up to 4000rpm. In my 1998 2-door XJ, 5-speed. I had to swap out the injector plugs with Power Tech plugs on the donor engine I had. Polarity is important for optimal performance. Some say it doesn't matter, but it really does. Very much value of $50.
