    Multi-point tow hooks, new bored 2.7L engine, custom paint. 3 inch adjustable Fabtech front coils, 2.5 inch rear AAL. Front Aussie locker. LED bed lights. Full LED conversion interior and exterior. Relentless Fabrication front and rear bumpers. 4X4innovation sliders. BAMF bed rack. CVT rooftop tent.
    If you have hod no problems with engine performance (i.e. not misfiring or arcing) then I would wait to change the wires until you are closer to 150k miles. As far as the coils, unless they are failing, you don't need to replace them as any type of maintenance.
