#18 of 22 07 Impala fuel economy upgrades by pocke59

I have an 07 Impala 3.9. Weekend Mechanic on DIY played a segment recently on fuel economy upgrades that improved their truck by supposedly almost 10mpg. Got me thinking, " Is there similar improvements for my Impala?" and if so, what are they, where can I get them? Their make over included new intake, air filer, headers and exhaust system from catalytic converter back. Need advice so I don't waste money, or throw it away on usless products. Thanks for your advice.

They improved mileage by 10 MPG, or 10%? Not sure what kind of truck they were starting with, but a 10 MPG improvement would be impressive on any vehicle...but 10% seems more than doable (though more realistic). And was this a new truck, or maybe an older non-fuel-injected vehicle? I had an '82 Ford F350 with a 390-V8 for awhile...it was getting 8 MPG when I bought it, but through repairing things like the fuel pump, giving it a tune up and rebuilding the carb I got it up to 11 MPG...only a 3 MPG improvement, but a 40% increase made a big difference in my gasoline purchases (just glad I sold it before gas prices spiked a few years ago). Anyway, my point is to increase the gas mileage of ANY vehicle by 10 MPG would be a pretty major feat, especially if they were starting with a newer vehicle.

Hey guys. I'm looking at upgrading some of the components on my 2001 3.8 Impala. I've run into some problems finding things like headers, exhaust, catalytic converters etc. that I can put on the car. Some of the issues i'm facing are the fact that I am in California and have to deal with Ca. emissions and want to avoid parts that will ultimately cost as much as a new car anyways. Has anybody on here dealt with this and have any suggestions?

I have a 2008 Impala LT with the 3500 moter in it. I am looking to put some upgrades on it but they are far and few. One of the things i want to do is upgrade the computer in it. Does anyone know where i can get one or where i can send it to? The other is cat back but the only one i found was like 800 bucks. I am in the process of getting the stuff for a homemade cold air intake. If anyone has any websites that have stuff for this power plant please let me know.
