I have my air intake rerouted to an after market air filter right by the exhaust manifold for warm air. I started with a grill block that grew into a rather silly looking nose extension/air dam; for which I get many looks. The underside is screened with window screen and partly painted. Wheel wells are partly covered;more in the back than front. I made side skirts that hang from the lip weld along the sides.Hub caps are taped up closing all the holes and painted. All this done with soda bottles and cans and duck tape. I did replace my rear duck tape wheel well covers with fake leather from an old sun roof cover.
I have my tires at 44psi.That was one of the first things that helped my MPG.
I watch the scangauge all the time and I do cut the engine off for lights.
BTW; if you are coasting with the engine off,the scangauge has to be set for HYBRID and the ignition switched to ON position to give credit for the extra distance.
