Default 96 cherokee

Ive got a 1996 Jeep Cherokee XJ 4.0 and have done a 3 inch lift 31x10 tires so far everything else is stock.
I just put a new head on it cause it overheaded and warped the old one. Would i get a good amount of horse power and decent gas milege from these parts.
k&n cold air intake
exhaust headers
catback exhaust system
throttle body spacer
bigger fuel injectors(not sure on these yet)

All that sounds good except the K&N and the bigger injectors.
K&N flows more air but lets in larger size dust and dirt particles.
Bigger injectors flow more fuel than the computer can compensate for thus bad MPG and overloaded O2 sensor.

The K&N is ok but buy an Amsoil filter for it and you will be good to go.
