Welcome to the Optima Forums Cory.
Congratulations on getting your 2016 Kia Optima EX model.
We are more than happy to help you find all of these items you need.
I have taken the time to hyperlink the item right next to your list below.
Let us know if you have any questions about these items!
• cold air intake (Air Intake Systems)
• throttle body spacer (Throttle Body Spacer)
• interior lighting (brighter) (2011-2019 Kia Optima Interior LED Kit)
• brighter headlight bulbs (If you have HIDs already) or (If you don't have HIDs but want them) or possibly (LEDs?)
• eventually exhaust but I’m nervous because sometimes 4 CYL engines don’t sound the best (CP-E - One of the best sounding)
• lastly some outer aesthetic changes (Exterior Product Collection)
