i have an 02 pathy and was wondering:
if i install an intake, will i notice any big difference like mileage and sound?
and what else can i do to boost mileage and performance?

Intakes will typically cause your gas mileage to decrease more. Yes, you'll gain about 8+/- horsepower and 10+/- lb/ft of torque, but gas will suffer.
I'm no expert, but this is what I concluded:
Typically, the ecu tries to maintain a certain balance between the ratio of air to fuel. Aftermarket intakes increase air flow, therefore the ecu will increase the amount of fuel it adds, to compensate.
Generally, when it comes to mileage versus performance, you typically will trade-off one for the other.
Lucas Heavy Duty Oil Stabilizer appears to have given me a few more miles per gallon, and a little more power too, in my 99 Blazer, but these numbers are probably around 3mpg and maybe 3-5 lb/ft of torque.
I use their Synthetic Oil Stabilizer in my 04 Sentra, with an aftermarket intake, and my average highway mileage is around 45-50 now. 38 stock, no additive.

how about those little resistor like adjustment knobs to adjust the intake air temperature sensor readings?
it is manuplating the data collected on intake air temp sensor and lies to the ecu to adjust fuel used per unit time. it seems reasonable. when it thinks air is hotter than before, it reduces the fuel amount to match the air to fuel ratio, am i correct? (becaus ei tcan not change the intake volume of air - because no forced induction)
sure this should work when engine is warm. unless it can not idle when air is too cold to make gasoline vaporized. as you know only gasoline vapor can be burnt. (that is why there are ideas about fuel vaporizers - in 30's and today - check yahoo groups.)

Those are actually a bunch of B/S. the mass air flow may short out, and you're screwed, like someone else I know who tried it. There's really no fooling the MAF sensor.

My bad, guys, let me try this again, like I said before, typically, upgrades will decrease mileage. This is only partly true. If you upgrade the intake, exhaust, etc, it will decrease gas mileage, if you drive the car like your in NASCAR.
On the flip side, if you drive normally, like you're not in any hurry to get anywhere, you will see some gains in gas mileage. I kinda got side tracked, because typically people upgrade the cars and drive like they're on a track.
If you're gentle with your vehicle, these parts will actually make the engine more efficiently, and you will gain mileage. Drive like you stole the car, and it'll suck down your gas like it's life depends on it, although you will see power gains.
The question is this, want more power or mileage?
If the information I have is correct, my car is averaging about 52mpg on the highway. When I'm not keeping the pedal on the floor. Just an example.

How can this be? Lucas Oil Stabilizer is merely a petroleum-based oil thickener ("bright stock") with no anti-wear, anti-friction additives. I avoid it in all applications.
Using thinner oils is a way to increase both mileage and power (by reducing hydrodynamic (parasitic) drag on the motor ... but may increase wear depending, depending ... Thicker lubricants decrease mileage ... although the drop may not be perceptable in most applications unless you maintain meticulous fuel records.
dmroberson, I'd have to conclude your mileage improvements were due to other factors and not the oil thickener.
I suppose someone could try a 5W-20 motor oil and see how it goes. Run it for 3,000 miles or so and track your mileage to look for improvements. Then do a UOA at the time of the oil drain to see if wear has stayed within acceptable levels.
Want to really increase your mileage cheaply? Avoid idling as much as possible. Also, increase your tire pressures as much as you dare without going over the maximums printed on the sidewalls.

It would depend on the new intake components. Typically, new intakes means revved up performance especially when it comes to noise reduction. As with improvement in performance, mounting new performance parts such as new radiators, spoilers, wheels, brakes and catalytic converter.
I added an intake and high flow exhaust and now I get 18mpg around town as long as I keep my foot out of it. Before, I was getting 16mpg, so the investment was worth it, especially at todays gas prices.
Those are actually a bunch of B/S. the mass air flow may short out, and you're screwed, like someone else I know who tried it. There's really no fooling the MAF sensor.
you may be correct for a stock MAF sensor but how about adjustible o2 sensors in tuned cars, you can easily fool the ecu? do that work? what do you think?

Those resistors only lean out the engine leading to detanation and increased heat. Plus on ebay they are selling them for ten bucks and they are a simple resistor found at radio shack.

Here is what you need to think about : The combustion of gasoline requires a lot more O2 than it does fuel, so more air = more molecules of O2.to better enable fuel to combust more regularly. Also if you advance timing a little bit, and use hirer octane fuel, your gas will take you further and it'll compinsate for the more money you spend. Just be careful your foot isn't too heavy, otherwise you might end up in a ditch somewhere, and with bad gas milage! =O

Gasoline and fuel are the same.?. Are you talking about more octane? b/c it sounds like alot of hot air up the @$$ if you know what i mean. And why worry about the high gas prices its fun to redline everywhere you go! You get there faster.

Run premium fuel. My '01 Pathy always gets 14L / 100km on regular, and 13L / 100km on premium (mixed city/hwy). The extra cost of premium is made up in better fuel economy, and I enjoy better throttle response/power too.
how about adjustible o2 sensors in tuned cars, you can easily fool the ecu? do that work?
"Fooling" the ECU to do anything is not a good idea when you have stock parts and want good fuel economy. OEMs are under considerable pressure to meet or exceed emissions and CAFE (Corporate Average Fuel Economy) regulations because an improvement with one car line can negate problems with another. They spend millions of dollars perfecting the engine tuning of the ECU in a stock configuration. Don't think you or anyone else can improve on it without millions of dollars of equipment and hundreds of hours testing.
Now "fooling" the ECU (or replacing it entirely) becomes beneficial and sometimes necessary when you put aftermarket parts that increase the engine's intake and exhaust efficiency.
