What are the best mods for a 2.2 to increase mpg?

LS_RIDA28

cai headers cat back exhaust

XM15

With a CAI and full exhaust I can get 37+mpg on the highway.

no mods will help your Mpg... well in most cases anyway... with and intake and exhaust your gunna wanna hear the car make noise so you'll step on it harder... you best mod for MPG would be to downgrade and get an aveo... lol

Driving style

Weight reduction (this is especially relevant for city driving)

Intake (this is more relevant to highway driving. CAI offers slightly more power but mpg will see no significant increase over a short-ram), header, exhaust.

Turbo =D

honestly if you want good gas economy.. DONT LET YOUR CAR BREATHE>..

so.. no intake, no exhaust, nothing.. keep it stock, keep a clean air filter.. fresh oil.. clean fuel filter..

im tellin ya... once ya let ur motor breathe.. say bye bye to gas economy

your going to go out and spend $600+ for a Intake/Header/Downpipe/Exhaust to gain 3-4mpg maybe... Driver Mod > all that

although getting those mods will also get you power and performace if you want it, and better mpg at the same time...

hold on, i thought added power kills gas not save it. cause isnt if you add more air into the engine, more fuel is required?

roadrage06

haha, that'd be me, i'm addicted to modding. If I owned a moped, I'd end up doing something to it..lol.

Well certainly that means no one else can ever turbo a moped.

Best mod to save on gas would be not romping on the car. I started driving slower, not accelerating faster like normal and my mpg went up.

Take the bus.

It's not about the power, it's about the restriction. It takes energy for the engine to suck in air and push out exhaust. The greater the restriction, the more energy is required and the more fuel needs to be burnt.

Just because you have i/h/e on your car doesn't mean that there's always more air going to your engine, it just means that there is less resistance to air entering and exiting your engine, allowing the energy that was once used to pump that air to be used for turning the crank.

See my post here for a better explanation.

I've wanted a Vespa 250GT for years, just so I could turbocharge it.
