this guy drives a 2001 civic ex. anyways, he says waxing your car makes you accelerate faster because the car is smooth so the wind passes it easier for better aerodynamics.. he also had his cold air intake wrapped in some foil tape which is used in HVAC applications to "reflect the heat".. this is why some people dont like honda tuners, sad...

Those statements are both true actually.
Not on the level he wishes they were, but they ARE true.
You would actually be amazed at how much of an effect dirt has on drag, not to mention the weight penalty...have you ever filled a pail with sand at the beach?
It is an incremental improvement at best, and would probably manifest itself as an MPG or so at highway speeds on long trips.
Same with the duct tape. The problem is that once the air is moving through the intake, ie the throttle opens, the air comes down to a temp very close to ambient in a very short time. It will never get colder than ambient without chemical intervention, so all it really accomplishes is to help prevent heat soak on the intake while sitting still.

Waxing doesn't really improve aerodynamics. Don't really want to get into it, but just look at golf balls and porting theories(dirt is a different issue; if you wash your car it wont be dirty, you can wax it to keep dirt off, but aerodynamics wont really improve).
As far as the foil tape goes, those can block out heat. Whether there's any performance gains, its negligible.-Kevin

The "insulation" is right in theory, but nothing useful for a street car. There are better products out there for the job.
The aerodynamic effect of a good wax does make a difference, but again, it's nothing a street car will ever make use of. Put it on a bumper-to-bumper road race at 100+mph, and the effects might be useful.
