What are some car parts that can improve gas mileage?

Question

So long as they either leave performance or boost it while increasing or not affecting gas mileage.

Answer 1

Just keep up on oil changes, keep spark plugs in good shape, make sure 02 sensors are fine, replace fuel filter, etc and you'll be good to go.

Answer 2

Make sure your mechanic checks your spark plug's wires or spark plugs themselves, a deffect in any of the two may cause your car to misfire and consume more gas.

- Also, never forget to verify the airfilter of your car, a dirty airfilter means a 10% increase in gas consumption of your car.

- Verify your oxygen sensor, an oxygen sensor in a good condition saves 40% and more on fuel!

Answer 5

Intake and exaust. Let your car breath by installing an aftermarket intake. And remember, the colder the air into the engine the better. Also opening up the exaust to let it exhale. Headers and larger pipe. Both of these will increase performance and boost fuel milage. WIN WIN......
