Welp finally usps decided to pay me a visit this morning. Delivered my Bosch 4 hope injectors. Getting ready for the install, curious and excited for the outcome. Just wonder if they r worth it or not. And another thing should I use regular engine oil to lube the o rings, or can I use petroleum jelly?

Congrats! :thumbsup:


Thanks man. Can a big different on start up and idle. A lot smoother for sure and throttle response is unbelievable better than it was. Power wise not much difference but then again it ain’t a hot rod lol. Will I gain any mpgs?

That is a good question. Most people say no and that the biggest improvements are a better idle and low end response. But you never know

O ok I see. Well I’m happy with the better idle and better throttle response that’s for sure.

I don't notice a change in mpg. Just the throttle response and a little better idle.

Well cherokee4life3 honest yes I would recommend for anyone with the 4.0. Ben driving with these injectors for a few days now and I can tell a positive change in idle, throttle response, low and mid range torque and start up as well. Highly highly recommend
