Fuel Mileage
 

I have a 2000 zr2 am looking to get some better fuel mileage. Has anyone seen any better fuel mileage from any aftermarket parts?(intake, exhuast, filter, and so on) If you have see gains how much were they? Please leave out normal maintence procedures such as changing air filter, plugs and wires and stuff like that. any help would be great.

Really no one has increased fuel mileage?

Why don't you search around a bit. This topic has been discussed in many threads.

One reason there have been no replies could be because you ruled out reporting the things that give the best mileage increases - normal maintainance. Swapping parts is a specious method. Plus this has discussed to death in other threads. Browse around and you'll find plenty of ideas.
