ok some of u might think this is stupid bc i drive a 08 accord sedan, but i installed a ram air intake last week and i haven't proven it yet but i believe that bc i did that. i increased my hp from 177 to about 185-190. its only been a week and i can tell u that the overall get up and go from the car is increased.

ill get a pic up soon.

and as for increasing hp with bolt on stuff what would i be able to do to my engine. i believe my engine type is a k24

thanks for looking

 

you have 160hp not 177 (btw your 160hp it to the crank not the wheels)...and the intake added MAYBE 4hp AT MOST. So there is no way you are pushin 180hp there is just no way. Bolt ons you can get a header and full exhaust. But you will only gain 10HP total AT MOST that’s including your intake.
If you want more power get cams they will make LOT MORE power then I/H/E all day long.

 

do the full exhaust, and cams like g22 said. cheapest upgrades and you'll get better gas mileage
