better mpg

I was wondering if anyone knew a way to increase the mpg. I'm getting about 15 right now and it sucks. I have a 98 EB edition V8 AWD. Oh and does that "vortex" piece in the intake really help? Cus i'm thinking i could just make one and test that out...

Or maybe a new exhaust would help too?

any help would be appreciated.

Some people have had sucess with it and some have not. If you want better gas you can redue the exhaust to open it up for a better flow. But I would not suggest it you like the quietness of the exhaust. a larger exhaust will make that V8 rumble

cold air intake, and exaust will help your gas a little bit

thanks for the help,

i built my own tornado and it didn't do anything...either i built it wrong, but it did look good, or it's just kinda gimmiky, i dunno. Yeah, i've decided that i'll have to go with exhaust and CAI. I was having trouble finding one for the 5.0 ltr. engine...any good links?

it looks like it'd be pretty hard to build a tornadofuelsaver cuz it looks like they paid a lot of attention to the fine details and slits on that thing.. they're pretty cheap if you buy em somewhere and i know someone that is getting 18 mpg on their explorer with that thing..
