2004 Jeep WJ bosch injector upgrade
I have been skimming the forum for quite some time now but finally decided to make a post.
I finally pulled the trigger on the 4-hole fuel injector upgrade on my WJ with 156,000 mi
and I sure am happy I did. I ended up getting them from flamethrower (injectordyne) on ebay.
The swap went easy after lubing the o-rings up a little and cleaning out the fuel rail.
As soon as I started the engine and rev'd her up a few times I noticed a smoother idle right away. Its not perfect but my water bottle doesnt shake in the cup holder anymore.
After the first test drive I noticed a tiny bit more power going up a few hills I drive every day that are long and steep, and a little better throttle response.
I cant say for sure yet If I have gotten better gas mileage but Im keeping track of it all week to see if I can get above 16mpg.
I will put an update up in a few days.
