What are some things i can do to my 2012 honda accored to give it more horse power?

My car is weak, it does alright with just me in the car but it needs more power so i can carry passangers and things in the trunk with out losing so much power. I enjoy driving fast and all though i know i don't have a race car or anything i enjoy upgrades because its more rewarding to customize a car then to buy it already done. I've already added a cold air intake but it only added like 15 to my HP and i was looking to bump it up about 150 more. My car is currently at 155 and i think 305 would be satisfying to me plus give me the pick up i need when i have passangers. I do enjoy a more throaty sound and the cold air intake made it sound more so, i'm bot going to rice it out but i would enjoy hearing my engine more.

Trade it in for a new Kia Stinger. 365 hp, stock.

I can't help someone that can't spell their own car's model as Accord.

There's not much you can do. Cars are meant to drive the way they are built. An Accord is a "daily driver", not a sports car.

Stick shift or auto? If manual, are you winding out in your gears? Most people are not willing to run high RPMs. If you car is not singing, you are not using the potential horsepower. Your horsepower is "peak" -- let the car scream.

If you want that much more H.P. You need to trade it in.

Stickers.

Stickers add more horsepower - even if you don't actually have the engine components that the stickers are advertising.

Pull the engine and transmission.
Sell them for a couple hundred bucks.
Buy a different K motor, bring it to a speed shop and ask for:

Then… Build a tranny, rework rest of the car.

Does anyone here believe he got 15 hp out of a cold-air intake?

I want to see a dyno report.

You'd need to reprogram the PROM, brain box, to get more HP. Otherwise, you'd need something like a Supercharger which can cost maybe $5,000++ to install. Still have to reprogram the PROM.
