Thanks for the input. I bought the K&N intake today, anything to help with these crazy gas prices. As far as it messing up our warrenties, I was told just hold on to the factory intake and and if something goes wrong just swap it back out and they would never know...

2-3 sounds like 52-78 miles more per tank. That sounds good to me. I agree its well worth it

Maybe 2-3 mpg, but nothing major. It's worth it in my opinion though.

Putting an aftermarket air intake on trying to get a MPG gain is one of the biggest 'rookie' mistakes made. Millions of $ are wasted this way every year, instead of spending the money on simple mods that really can improve fuel economy.

Got to agree with HankL on this.
I personally installed a set of Gibson log headers and their Swept Side single exhaust (the lowest restriction by their claims) on my 2005 Ram 1500 HEMI. I meticulously kept extensive MPG measurements using the odometer and fillup gallons. I ran these tests many times over several months. With stock parts, with just the headers, with just the Gibson exhaust, with both the headers and exhaust. I all tests, I saw NO consistent difference that was measureable. The best MPG I ever received was 18.0 mpg with the Gibson exhaust and headers installed. This was for the same 150 mile trip @ 70 mph on cruise control. On exactly the same run I achieved 18.1 mpg with the stock exhaust manifold and muffler. $1,200 dollars poorer, the stuff sits rusting in my shed.
I suspect all these "breathing" enhancers may have some affect, but they probable only show up on the high end--towing big loads, quarter mile runs, full throttle accelerations. If you doing these upgrades for that purpose, then it might be worth it. But, for mpg in the regular driving range--light throttle, 1800-2200 rpm--its better to put the money into accessories, gas, and maintenance.
BTW, I've also ran tests using different motor oils: Exxon Superflow (dino), Mobil-1, and Royal Purple. You guessed it, only a small (.2-.5 mpg) measureable difference in MPGs. UOAs on all oil changes, showed NO measureable wear differences.
