(aside from the obvious tips on driving slower ...)
I've read a number of posts suggesting that a low restriction cotton-gauze filter can marginally increase fuel economy and power. I've heard other speak in favor of mods like cold air intake, headers, cat-back exhaust providing marginal benefit.
Assuming that the maintenance is all kosher and the proper driving techniques are in place, what mods (in the few hundred dollar range) would hold some promise of delivering improved fuel economy for an '05 Accord LX i4 M5?
