It is time for the Jeep Wrangler YJ to get a fuel performance upgrade with some new Fuel Injectors. Mine are original and they are a single port injector. The new injectors are from a Ford 5.0 and they have 4 ports.
This is one of the best upgrades I have done to the Jeep. It idles and runs so much smoother it is hard to describe. It also starts much quicker.
Can't recommend this enough for anyone with an old Wrangler whether a 4 or a 6 cylinder.
