Bosch 3rd Generation 4 Hole Upgrade Fuel Injectors for 1999 - 2006 Jeep 4.0L Engines

Good quality

Huge difference between these and budget injectors. Went through two sets of cheaper versions and couldn’t get a set that wouldn’t leak down into the cylinders. The Bosch work perfectly. Better startup, holds pressure, and better mileage.

Throws code for too rich.

These injectors throw a code for running rich. No contact from the seller when I called and emailed. Don’t buy!

Fast Shipping - So far so good

I needed to replace the original injectors on my 2006 LJ. It was going to take weeks to get mopar replacements from several sites and I needed to get back on the road ASAP. Shipping was fast and reasonable. The Jeep runs great now, noticeably smoother. I’m not sure if that’s the 4-hole design or the fact that the old injectors were so worn out.
