What are some aftermarket engine parts that would help bring up the fuel economy of the rsx?

intake the most also a clean freshly waxed car improves fuel economy by up to 7% by aerodynamics alone

I gained some millage on my car when I put my K-Pro on. Went from getting 500kms to a tank on average to 570-580kms/ tank. And that no even highway driving.

lowerd springs, intake, exhaust. of course that will all go to waste when youre shifting out of 1st gear at 13MPH to maximize fuel economy.

my understanding is that the since cold air is denser, you get more oxygen per volume, and the ecu detects that there's more oxygen and therefore compensates by adding more fuel (to get the desired a/f ratio)

EDIT: not sure if that would cause that big a difference though....

or since it's hotter in the summer, the heat makes it expand and so your car thinks there's more gas in your tank since the volume is bigger. which leads to you driving more before the empty light comes on.

I hope this is a joke. :p
...actually intake and exhaust will improve gas mileage slightly.

Most people don't notice the improvement though since they are going to tend to stomp on the gas more for a while after they get them...

Also depending on your location, in winter season more alcohol is added to gasoline to help engines on cold starts. Alcohol burns way faster than gasoline.

Shifting too early can also effect gas mileage. The engine is working harder to maintain speed at lower shifts defeating the purpose to save gas. Throttle input is what really matters. Just my 2 cents:wavey:
