Bosch 12 Hole Injectors + 62mm Throttle Bodies

Hi my fellow Wrangler Brothers,

My son and I are what I call 'Extreme Enthusiasts'. Our hobby and passion is Jeeps, particularly the 4.0L engines and Cherokees. We do Cherokees because they are cheaper than Wranglers but many of the parts are the same or similar.
We are not a shop or business, just a father and son team working together on our own vehicles in our garage at home.

Our Jeep Stable includes--
2- '85 factory Cherokees with the 2.1L turbodiesel, one is SN -000005
2- lifted Cherokees, one with Sprintex SC, other BT M90 supercharger
1- lowered 'RaceJeep' Cherokee with red M62 supercharger thru the hood
1- stock 'Daily' Cherokee getting many 'hand-me-down' mods
1- XJ Buggy- 1 tons, 42" Pitbulls, Bilstein air struts, chopped and caged
1- 'Beater' off-road XJ- was free and added used 35s cut fenders and diffs
1- Ranger with XJ 4.0 engine AW4 and 232, SD axles linked coilovers 42s
2- Cherokees being fixed and cleaned to flip and sell
4- 5 speed parts XJs, rusted out but with all parts for 5 speed conversions
1- MJ shell for future project lowered dually
4- parts XJs

We spend a great deal of money on our Jeep hobby and have bought many parts and accessories. Some work, others fail. When we find something that works, we buy multiples to get a better price and save on shipping. Most of the time we use all the parts that I buy on our personal Jeeps but sometimes I have unused 'leftovers'. When they're gone, they're gone.

We research everything and try and share and include as much information as possible for others to learn and enjoy.

Marty and Ben

We use these 12 hole injectors on our personal Jeeps.
We had the 4 hole injectors 703 and 784s in our Jeeps and swore by them. We changed them out to these newer 12 hole injectors and now swear by these.

We immediately noticed easier starting, smoother idle, quicker throttle response, seams more powerful.
My son noticed about a 2mpg gain every day city driving and he doesn't drive with any concern or attempt for mileage.

If you have a set of 4 hole 703 or 784 injectors, IDK if it is worth it to switch them out.
If you have the original 1 hole injectors, it is Most definitely worth it changing to these 12 hole injectors.
Your results may vary but many have noticed the improvements.
Just my 2 cents.

Would these fit in a 3.6L V6 2012 Wrangler? or are these differently designed?
