Anybody have a 4.0l ford V6 with intake or exhuast?

School started again and times are tightening up. I want to save some money since I have to drive way more than I did during the summer.
I get pretty decent gas mileage now (compared to my friends with v8s) but I think I can do a little bit better with a less restrictive air intake and exhaust.
I'm thinking thrush mufflers because they arent as expensive as flowmasters the other name brands.
I dont need alot of sound. Id even be content if it were no louder than stock. I just want it to breathe a bit better.
For the intake the first thought that came to mind was K&N, but I remember an article I found awhile back (http://www.bobistheoilguy.com/airfilter/airtest3.htm) and did not jump on it.
Anybody have problems with the oil for the filters messing with the mass airflow sensors?
 
Haven't had any problems with sensors and my K&N filter on a Ford 4.2 V-6.
 
My wife's Explorer Sport Trac (4.0L SOHC) has a Bassani exhaust and a cold air setup and it makes about 8hp (peak) more than stock, sounds good, and she gets about 3mpg more than when it was stock.

I actually have another cold air kit. It's for '02-'05 Explorer Sport, Sport Trac, and Ranger with 4.0L. If that's what you have pm me and we can discuss. It's brand new in the box with a Pro-M mass air meter too.

I had KnN and flowmaster on my 4.0sohc explorer sport. Didnt notice a difference in MPG, if anything, it made me stick my right foot a lil bit harder.
 
I'm pretty good about controlling my foot. I know how the relationship works so I accelerate slowly and don't care if people pass me up. I'll usually catch up with them at the next red light anyway. My morning commute takes just over an hour to drive 15 miles.
 
Racer nailed it. I was getting 13-15 MPG in my 5.4lt Triton f150. I started watching my foot. Not accelerating hard, put in neutral on longer downhills, and keep my air filter clean and stay current on oil changes and now I get 20mpg-22mpg outta that big ol v8 on my 30-45 minute drive to work. No interstate or highway.

Your biggest mpg gains come from controlling your right foot.

Never tried it myself on any of my blue ovals (currently all my cars are Fords, running 3.0L v6, 4.0L v6, a 4.5L v6, and a 5.4L v8), but I know someone who installed a cold air intake on their Explorer with the same 4.0 I have. They claimed it bought them a 2-3 mpg improvement (up to ~21 from 18). I was thinking about doing the same thing to my 4.0, but I drive pretty light on the pedal, and I average 21 to start with anyways, so I don't know if the difference would be as noticeable.

If you got the cash AND plan on keeping the car for long enough to make it worth the investment, I say go for it.
 
Thats about where I am. Just above 20.
Almost bought a scooter this summer to get 90mpg, which would pay for itself in a few months just in the amount of money I would save on gas lol
