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 Matthew Flores

First of all it only took me 2 days to get it to my door, it's amazing. The fact that the parts store charges the same price for any of the 6 I have in this kit made a deal I couldn't refuse and I'm glad I didn't. I installed them on my '04 Jeep Grand Cherokee with a 4.0 liter inline 6 engine, I noticed a big difference in the smooth idle and it has much better throttle response. I haven't checked the numbers, but I'm pretty sure I'm moving further down the tank than before, so that helps as well.
