Hi. Yes, there are a few mods that I like most, but it is hard to say what is most effective, since some are only useful in certain driving conditions. Others are only effective because the help hypermiling. For example, and injector kill is best when you are doing EOC, not just sitting at traffic lights every so often. So in no particular order:

air dam
grill block
side skirts
wheel skirts
injector switch
1992 VX wheels
alternator switch
1993 CX transmission
power steering delete
plug-in deep cycle battery
200+ lbs (91 kg) weight loss


See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
