Replacing the stock 1 hole injectors with 12 hole injectors to see if there is a power and/or mpg gain. The stock injectors are possible original so be aware that any gains made, might have been made with factory replacement injectors. I do believe the better atomization of the 12 hole helped.
These are the remanufactured Bosch 12 hole fuel injectors. This link may die, but the seller generally has others available so the second link is to the seller:

Now for set of plugs and wires, don't forget the PCV as well, the best luck on the PCV that I have had was the one from the dealer

I almost did plugs and wires at the same time, but they have definitely been replaced within the last 60k miles (my best guess). They are still on the list though!

Keeping the injectors clean is very important. However better atomizing the fuel will increase efficiency and power because it will burn better.

Interesting video … Back in the day, I loved that engine. But I’m an old buzzard, now, and I prefer the 3.6 MOPAR engine, because it’s super-efficient. That 3.6 engine will do an honest 30+ mpg on the road in a boxy van.

You may like the next review then, it will have the 3.6 V6.

Thank you for your video, it’s been a year since your install of the 12 hole, how has your Jeep been running? Thanks again for your video.

Everything still seems good. I'm getting just under 17 mpg which I think I was at 19 before, but I've now added a bit of a lift and 32" tires. I'm happy with the results. The one area that seems to not be quite as good is with heat soak. I didn't notice the problem much before the injectors, but now it seems to be a little more of an issue. Usually if it sits for 10-30 minutes after running up to full temp it will have a heat soak issue that will either reduce power quite a lot, or it wont start for the first crank or two. I don't know if it has to do with the 12 hole vs 1 hole injectors, or if it's just something I ran into for other reasons.
