Fuel Injectors

[Saddle Tramp]

I need to change out the intake manifold on my 1999 4.0 Wrangler and figure that I may as well freshen up the injectors while doing the switch. What’s best?

unless your going to increase the air/fuel flow through out the entire engine (intake, heads, increse combustion, exhaust), your just throwing money at un-needed parts.
