K&N and Flowmasters improve MPG?
#5
Yes, I have flowmasters and the Volant intake. On my 4.6 and get from 2 to 3 mpg better. The only thing is you have to be aware that if you so this stuff you will want to play with it and keep the exhaust note in the "sweeet" area and therefore consume more fuel. However, if you drive like you did before it will save you fuel.

No, not really noticeable anyway. I do speak from experience.
I put over 150K miles on my now deceased '04 Lariat 4x4 with the 5.4, K&N and Flowmaster catback. Those were my first two mods when I bought the truck new. I also ran a K&N Cold Air intake for a couple years. (No improvement, just noise).
My current replacement '05 gets the same numbers with stock exhaust and a drop in K&N filter. Around 13-15 around town. 16-18 on the highway.
The biggest improvement in mpg's I've realized is from using a Superchips Flashpaq programmer. Both the 87 octane performance and the Mileage XS tunes improved my mileage around 2-3 mpgs on average on both my trucks. I can see 16-17 around town and 19-20 on the hwy.
