hey i want to buy the f-sport air intake and exhaust but i was wundering if they increase or decrease your fuel efficiency. i know the intake does by a bit but i want to know if the exhaust will to. if they do than the parts are basically free because they will pay for themselves after a period of time. for example... lets say i get 20mpg now and pay 3000$ per year for gas. if gas costs 3$ per gallon then i used 1000 gallons of gas and traveled 20,000 miles. If my fuel economy increased to 25mpg and i traveled the same distance of 20,000 miles then i would only use 800 gallons of gas costing me 2400$ saving me 600$ that year on gas. now seeing as i just pulled these numbers out of my *** (though the math is correct) the savings are probably inaccurate because gas price isn't exact, i don't necessarily have 20mpg or will have 25mpg in the future and don't travel 20,000 miles per year etc... but you get the math/point. if the numbers are accurate or close to accurate than after one year, the fuel intake pays for itself and after 3 years, both products pay for themselves and i start saving money. i just want to know if the exhaust will help my fuel efficiency (not to mention performance lol)

I would think the improved gas mileage would be negligible because you would be dipping into the throttle more often so you can hear the parts you paid for. Either way, you are spending the cash now with the hopes of a return.

They should increase MPG at higher RPM maybe 2500 & higher maybe decrease below

This is typically the case most find.

Another thing, do not fall victim to those magnetic fuel line gizmos that promise better MPG. They never work and the government had a class action suit on one manufacturer for false claims.

do not base it on improved gas mileage.. just assume your going to be getting about the same and if ur willing to spend the money on the parts then get them.. the differrence probably wont be noticeable

Put it another way-

If there was something cheap that effectively increased gas mileage with no other drawbacks why wouldn't they have put it on the car in the first place to advertise offering even better mileage from the vehicle?

If you're looking to justify a mod by the amount of money it will SAVE you, then you probably shouldn't be modding at all =)

There is something you can do... but its not cheap.

Lightweight wheels and tires.

Lightweight driveshaft would help out as well. Decreasing rotational mass is your best bet.

dont for get CF hood and trunk saves more weight too, synthetic oil . You can go on and on...

Stop thinking and just do it. If you dont jump on the gas your saving more gas. It is the way you drive your car.

It is like me I have to have my brakes replaced and i only have 10K on them. I am not heavy on the brake, i just can feel the pedals because i have no feeling in my foot.
That is my opinion!!!

cf hoods weigh almost the same as our hoods...

Save money? No. Will you car look and sound better? Yes. Conclusion, just do it.

changing your driving style will improve mpg greater than any mod...maybe changing to a lighter weight oil too

change your car to the "SNOW" mode in ECT, and light foot on the gas, you may see an increase in MPG

ok look... i'm not actualy interested in increaseing my MPG! al gore can go to hell for all i care! lol. i'm in high school and my dad got me an IS250 awd for having a 94% avj in school (which is good) / 17th birthday present. I just need to justify to him reasons for why i should get 2grand worth of ups lol. i'm a student so i cant rly get the money myself. basically, as long as the up will increase my mpg, be legal, and not void my warranty, i can get it lol. so ne ideas would be greatly appreciated
