Hey everyone,

I am a first time owner of an '08 Ford F-150 Lariat and I am looking to get better gas mileage. The truck has a 5" lift with 35" tires and am looking to get better MPG.

I have spoke to some people about a K&N cold intake system..A super chip...

Please help me get the most bang for my buck!

Thank you in advance.

I have a K&N Cold Air Intake, and just got back from a 1000 mile trip. I also have the Edge programmer on transmission only setting. I average 15.2 miles per gallon. I have 20 inch rims with oversized tires, no lift. It is a 4X4. Since returning back to city driving, mileage has gone back down to 14 MPG. It will probably go lower if I don't get back out on the highway for a longer drive.

Thank you. What year is your truck?

How much does an edge programmer cost? What other benefits did the programmer give you?

I hate to be that kill-joy but the thing that will make the biggest difference in your mpg will be to take that lift out and go back to stock size tires and wheels.

I've got about 18 MPG Screw 2WD with Rousch CAI and Edge Evo setting #2.
I don't go over 65 MPH on the highway though. It literally sucks above 65 MPH.

what kind of MPG you looking for ?? gears would help you...

Mod (Ret.)

A five inch lift, and 35's? And concerned with fuel mileage?

Those 35's added a whole bunch more of rotating mass (weight) to the drive train. As mentioned by techrep, gears may help in the way of allowing that much larger "mass" to rotate, but doubtfull it will gain you any significant MPG.

My guess is that this truck was bought because it had a cool lift with large tires. Stick with that. If mileage is a concern, drop the truck to stock, and put a set of stock tires and rims back on.

And forget the CAI; you already have one. All fuel injected engines these days draw air from the front. Our Fords run the snorkle of the air filter box to the side fender, which in turn draws nice cool air from the front. Adding this K&N kit IMO will actually defeat this, as they use an open box that their filter is within that is supposed to seal itself against the hood when its closed. The large open cone filter may draw more air than the stock cone filter, but it would be warmer engine air with its designed box the kit comes with. Other manufacturers sell an inclosed box that their cone filter is inclosed within, and these run a snorkle to the same location as stock. So what do you gain for that $250.00 to $300.00 plus investment? Not much, unless your into looks.

A tuner would give you the most bang for your buck, but MPG is usually going to drop further, as the added performance gains that a tune gives you are enjoyed by the right foot being used a bit harder.

Bucko is right on about the tuner. It has taken me a month to get my right foot out of it. Once that happened, I'm on stock tires and suspension and with 70/30 around town to highway I average anywhere between 16 and 18.
