Installing 4 hole fuel Injector upgrade on a Jeep motor.

**1,000 Subscribers**. THANK YOU EVERYONE!!!!
Part 1 of a 2 part series on installing 4 hole fuel injectors on my 1999 Jeep Cherokee 4.0. After a good bit of research, I determined it was time to go to the 4 hole injectors.
Looking for better fuel mileage, smoother idle and better throttle response.
This video covers the installation and some background on why 4 hole injectors may be the way to go for your Jeep.
In a few months, I’ll come back with my findings. Do I get better fuel mileage, hows the throttle response and is the idle smooth as silk??
