Ford truck owners, if you're dealing with rough idling, poor fuel economy, or misfires on your F150, these INFINAUTO fuel injectors might be exactly what you need. I just installed this 8-piece set on my 1998 F150 with the 4.6L engine, and the difference is night and day. The metal and plastic construction feels solid, and the yellow color makes them easy to identify during installation. Each injector measures about 3.03x1.30x0.96 inches and features 4-hole disc design for better fuel atomization. They're 12V DC with 2-pin connectors and come with O-rings pre-installed, which saves a ton of time. The fitment is extensive - works with F150s from 1990-2003 with 4.6L and 5.0L engines, plus various Broncos, Expeditions, and even some Mustangs and Lincoln models. Installation isn't too complicated if you're mechanically inclined, but having a professional do it ensures everything gets tuned properly afterward. Since installing mine, my truck starts instantly, idles smoothly, and I've already noticed better fuel mileage. The quality control seems excellent - no leaks or issues with any of the eight injectors. They directly replace the old units without any modifications needed. If your Ford truck is showing its age with fuel delivery issues, this complete set gives you everything needed to restore performance without breaking the bank. Just make sure to check your specific year and engine size before ordering to ensure proper fitment.
