I have an 08 Honda Civic Ex and im wanting to add after market parts to my car to give it alittle more HP and try an Up the MPG. And from what ive been told is that the best ways to do this is cold air intake, exhaust, preformunce spark plus, and a chip thats technical name escapes me. So im looking for professional advice as to the best and most cost effective ways to do what i need and the best parts that can get that. Also is theres anything else i missed that can get me what i need

These seem to be mutually exclusive goals.

Don't touch the spark plugs. You will not gain mileage from plugs, and these are good for 100,000 miles or more (a LOT more).


You want performance, mod for that.
You want mileage, mod for mileage.
Can't easily have both.

Mileage? I'd do stuff like
use 0w20 oil.
Low rolling resistance tires, narrow and pumped to the max.
Clean up the aerodynamics.
Change driving habits.

JMHO. YMMV. HTH.

And what if i were to put a cold air, exhaust and chip. Will it effect(lessen) the gas mileage i have now? And if i were what would be the best parts and where would be the best places to buy them

IMO Yes.... along with more noise, and we all know that causes you to exercise your right foot a lot more often.

IDK. I'm a dealer tech. I deal with 99% strictly stock stuff. Very few cars I see have any mods.

Maybe you can do some searching on this site.
Maybe someone else will chime in with ideas.

if you are conscious and don't step on the gas, and if you can find a good mod that effectively improves the low range torque, yes, you can get better gas mileage while getting more torque (not power, torque) in the low RPM, especially. Meaning you don't need to push the throttle as much to get to reasonable speeds.

In the 7th gen (up to 2005), honda adjustment did not make the best use of the SOHC VTEC engine , so crower made a good cam called stage 1 - drop in and it will use what the engine/ECU have to offer in stock form. Power increased and mileage actually improved.
However, that is not common. Also, that was the only one mod that is drop-in that actually gave enough changes in power/torque for that engine.

Unfortunately i am not aware of mods such as this for the 8th generation (2006+).
Maybe someone did and will chime in.

g'luck and be aware of your right foot - that is what gives the best mileage. releasing the throttle and letting the car coast in gear was what actually gives me best mileage, sicne injection cuts fuel completely.
