Not those-They would not be good for many reasons: the arent 24lb-they arent from a 4.0L-im not exactly sure but i dont think theyre 4 hole spray--you want something from a 4.0 4.6 or 5L, truck-24lbs/hr, or the EV6 style dodge neon injectors, they add like 3mpgs...everyone on here who does injector swaps has em or ford explorer injectors--i have LS1s from a camaro, they add power but take like 3 mpgs away if you want them-$30 shipped.

Everyone should back me up on what i said

24#per/Hr injectors are to big for stock 4.0l Jeep moter.

So Maybe you can help me I have a 1990 4.0. Could I get Injectors from like a Newer one like later 90s and just drop them in and expect more HP? Will it work? Will I see more HP? Will I need a Tune? How can I get it Tuned? Please help message me Thanks

x2, most guys with the 4.6 or 4.7 strokers run the 24lb injectors.


Those are bosch injectors and they are 4 hole. It doesnt say that they came out of a 4.0 either.

Get the injectors out of a 2.4L 2nd gen neon. last 3 digits should be 703. these are the best injectors for a renix, which is what you have.

But What Kind of car can I take the Injectors out of to get more power? I don't want stock ones I just want a little more power lol

you cant just pump more fuel into the system and get more power. it will run rich and you will waste fuel. to get more power you need three(really 4) things: fuel, spark, air (and efficiency) if you get an injector that just pumps more fuel the computer is going to retard the injectors fuel output. The reason everyone is saying to get an injector with a 4hole pattern is exactly what the video covers. atomization or efficiency in the burn. if you can burn efficiently you will notice not only better throttle response (such as i did) but also increase fuel mileage. you can look at the spark, fuel, air stuff as an equilateral triangle. you can not increase one side of an equilateral triangle and still have it be equal right? well same thing happens with your engine. when you add a cold air intake, its not letting more air in (the 6x9 air filter has the same surface area as a cone filter) but rather its making the air that the engine is getting colder, making the burn more efficient, and making your engine happier.

hhhmmm Well I have the four **** Iridium Fusion Spark plugs the Best My Store sells and a K&N Filter. I was just told I could put injectors from like a later 90's Jeep into my 4.0. lol Oh Well It looks like I have some investing to do.
