So here's a few pics of my '13 Spark LS & what I've done so far to it.
15" RTX Halo wheels & Kumho PA31 195/50R15 tires
Custom 1-3/4" cat-back exhaust with Magnaflow muffler & chrome tip
DC Sports cold-air intake kit (very happy with this mod - both sound & improved throttle response!!!)
JET Performance mass air flow sensor
Pivot voltage stabilizer
Plasti-Dip covered front & rear Bowtie's
SpeedDawg shift knob & "cut-down" shaft
