Calling all 6.0 techs.
I have a 2004 F-250. I know about the fabbing I will have to do to install a 6637 filter. What I need to know is " How will this effect the mass air flow sensor and will it help with fuel mileage - temp on the engine ? I know on my 7.3, it worked wonders for me. I will also be doing a muffler and cat delete. All your thoughts will help. Thanks

Not sure what a 6637 filter is, but if it's some kind of an "upgrade" then you're MUCH better off with the stock filter. It will flow a LOT more air and is actually very easy to change if you know the proper procedure. It will also hold about 3.5 lbs of dirt before it needs changed. There are some folks on here with 208K miles on the factory filter.

6637 is a NAPA air filter that everybody put on the 7.3. It worked good for a lot of things. I don't know if I put that much air into the engine, will it mess with the mass flow sensor and will it help fuel milage? I don't know alot about the 6.0s

It's not a good switch. The blue synthetic 6.0 filter made by Donaldson is a LOT better.

I'm all for that. I run a 3.5" downpipe to 4" straight pipe.

Fuel mileage is all about your right foot and keeping RPM's under 2000. Big tires will hurt. One thing I can suggest is having your FICM/IDM tuned by Power Hungry Performance - Feed your hunger for POWER!. It will help throttle response and fuel mileage.

Thanks. I will check them out. This is one of my work trucks. No big tire or anything like that. I don't know how my men drive it everyday. It uses four tanks a week to my 7.3s three tanks a week
