Air filters that give better gas mileage
Hi all:
Okay, I'm not sure I understand this one, and would like one of you guys to
help me:
I've seen after market filters that claim to give better gas mileage. Now,
I think the jeeps use an oxygen sensor in the exhaust system. So, since the
oxygen is kept the same, how can an after market filter give better fuel
economy? Is there any objective, third party test results that support their
claims?
Thanks
Lloyd Hanning

The claim is the "brand x" air filter flows air more freely than "brand y".
Basically, any filter is better than no filter or a clogged filter. Keeping
that in mind a filter with a larger surface area will catch more dirt and
probably last longer. The K&N (oiled cloth) filters are reusable but expensive.
I haven't seen any "third party" tests, just a lot of vendor fluff and paid for
testimonials.
While we're on the subject of mileage boosters.. stay away from the snakeoil
additives and air swirlly things. Unless of course you like flushing money.

Re: Air filters that give better gas mileage
I saw in a Four Wheel Magazine where they challenged some claims and,
according to their unbiased opinion of their prospective sponsors, they said
the swirl thing actually did produce a measurable albeit slight gain. I
wouldn't waste my money on it even if I believed it, though.
My all-time favorite still has to be the "rare Earth magnet" that clamps
over the fuel line. It's advertised with a pretty picture of the
positively/negatively charged gasoline molecules ionically breezing through
your gas line. I shouldn't throw stones, though. I could use the
therapeutic peace of mind that comes from knowing that my gas is perfectly
ordered into little "$$$" signs at the molecular level:)
P.S. My buddy in elementary school proved to me that 1 + 1 = 1 ...

Re: Air filters that give better gas mileage
I think you have it figured out just right!
New engines aren't like the old carb ones where you can add a little air
and a little exhaust and get a boost.
