How to change fuel injectors and install a heat shield to help prevent heat soak on a Jeep 4.0 Engine

Very good, detailed instructions. One thing that helped me is I ran the jeep and pulled the relay for the fuel pump, and it relived all of that pressure.

I had heat soak on the #3 inj for several months. Tried to jury rig some insulation, but no dice. Decided to go with 4 hole injectors used but cleaned and tested from K Suspension, and the DE heat shield kit. I found that the throttle response seemed more immediate and precise, but maybe that's because they are clean and fresh? Your presentation of the procedure was very clear.

Nice, I’ll be installing mine tomorrow. Don’t know if you noticed but that first injector you removed and showed up close was cracked

Excellent video, lots of good information. Will be doing my injections soon... It's totally time. And the heat shielding is an excellent idea.

Thanks for your video, how has the heat shield been working, any noticeable change? Thanks again.

Neon injector plugs fit and are built better, .

Could you put the injector covers on before you install them back on the engine?

After making this video it seems the Duralast is now a better value. Either way they were the same unit as of the making of this video
