I have a blown intake manifold gasket burning oil at a rate of 600 miles per qt. and running rich but still about 17 MPG it's a 99 dakota sport ext cab 3.9l 4x4 i was looking to replace the intake with the hughes stage 1 and the stage 1 TB. My question is would it be worth it to upgrade or not I'm not doing internal work on the motor till it dies i have JBA headers, CAI, and a flowmaster 44 series dual exhaust.
