I got s 2011 Honda Accord EX-L v6 I-vtec 3.5L coupe I want yalls

Ok so other than posted above the car is in excellent condition not a thing wrong with it. I'm not that much of a car buff but can work my way around things. So my question for y all is I want to have better performance for the engine. What can I do and what will I need to do this. Also if your willing can you also give me an explanation of what it is that I'm doing to make the car better.

Make sure the horn works. And wear a hat while driving.

Leave it alone
