Well I can't explain it. I also can't see how changing the filter should
have affected the fuel economy by a measurable amount. Did you reset the PCM
when you installed the filter? I suppose it is possible that oil from the
filter coated the MAF and screwed up the information provided by the MAF to
the PCM, but even in this case the PCM should have been able to cmpensate
and return the A/F to the correct value (and if it couldn't, it should turn
on the CEL). Another possible explanation is that you actually decreased the
performance of the engine, limiting your ability to burn gas (I think it is
possible you are confusing increases noise with increased performance). A
properly functioning PCM should easily be able to compensate for minor
changes in an air filter. You didn't change tires around the same time you
changed the filter by any chance? Or maybe the fuel formulation in your area
changed? I just can't come up with a rational explanation for a 10% increase
in fuel economy related to just changing the air filter. If you are not at
WOT, the air filter isn't a significant source of inlet restriction unless
it is practically plugged up and in this case, you'd have bigger problems.

nope - we don't have cars on planet bulldetector. i just take your

Don't you think that is unusual, assuming that changing the air filter was
the readon for a large increase in fuel economy? If reducing the air filter
restriction could increase fuel economy by 10%, don't you think you should
see the fuel economy decrease as the filter accumulates dirt and the filter
restriction increases? I know you said your filter was not a K&N, but I
assume it is similar. K&Ns own data shows a substantial increase in the
filter restricition as it accumulates dirt. K&N shows a dirty K&N filter to
be more restricitive than a clean paper filter. It seems to me you can't get
a 10% increase in fuel economy by changing to a less restricitive filter and
not also get a measurable decrease in fuel economy as that filter loads up
with dirt.

so, given that efi controls the engine management, and the throttle is a
much more significant restriction on air intake than any but the most
seriously clogged filter, how exactly can that be happening? oh, and
you need to account for the air being hotter and therefore less dense
[!] inside the engine compartment where this new air intake of your
resides. thanks.

rubbish. tank to tank, fuel economy on any car varies much more widely
than that.

I never let it accumulate dirt. I cleaned it by vacuuming it and also
cleaned and re-oiled it every other oil change. I was worried about dirt
getting into the engine, too, so I doubled the maintenance.
In the winter the mileage would fall off to about 40, but that was it.

Easy, it did. You're in the Honda group, right? Don't you ever talk to any
of the guys that modify their Hondas? They're all over the place.
Oh, forget it. You're a keyboard Know-It-All, and don't actually talk to
real people.
