Fresh copper plugs, new coils, and a new air filter. That's it. No power adders exist for a 3.7 V6 unless you go to a custom shop and get a custom tune. You could get some gears. That would help you with the low end.
Typically exhaust systems lose bottom end and gain top end. Same with cold air intakes.
