If it has a screen, remove it. That will cause a lean condition.

If it doesn't have a screen there's not much you can do with it since all it does is measure the volume and temperature of the incoming air.
#8 of 24 Any bolt on MPG improvements for 2004 chevy2500
Jun 26, 2008 (6:19 am)
I own a 2004 chevy 2500 with a 6.0L and a 3.73 axle ratio. I am wondering if anyone as a similiar truck or same size motor that has put any bolt on's such as a air intake kit, fuel catalyst system, computer programmer, throttle body spacer, or anything else that has gotten any real world MPG improvements. I read about alot of the products that "SAY" they give you MPG increases. I wondering if anybody as any experiences with the products?

The items that you've listed will do two things. Increase in cab noise and lighten your wallet. The manufacturer would've done all of the above in their quest for bragging rights in increased mpg if they beleived it would've helped.

I'd do the switch to synthetic. Also change the plugs and wires even though GM says it's good to 100K. You will probably show a little increase with the changes. Nothing major but a little here and a little there adds up.

that sounds like a great idea. Would you be able to let me in on some info on what it takes make it run on hydrogen and did you notice any power loss?
