I have a life. And I don't take hardly anything very seriously.

You asked an open-ended question for which the only possible answer is, yes.
And, you did it in all caps.

All I did was miss the punctuation at the end of a sentence. Get a life, and
don't take this newsgroup thing so seriously.

Obviously reading comprehension isn't big with you either..

The original posting, which was frome me, not Jeff said:

"no there are not. why are you YELLING AT US?" <--- notice question mark?

And just to return your compliment - I don't think you could get a life
if it was handed to you.

Why don't you go away and play with the traffic? I6 will do!

The answer is basically (and it is much nicer when you aren't yelling) that
higher flow filters won't improve your mileage at all.  They _can_ improve
your performance with the throttle wide open IF the airflow is the limiting
factor (which it is not on a stock vehicle).  If you have done other things
to increase engine horsepower (and that includes a high flow exhaust system
and modified firmware at the very least), it's possible to get into a
situation where airflow limits you at maximum throttle and a high flow air
filter system can help a bit.

A lot of the high flow systems get their flow rate at the expense of
reduced filter efficiency.  That's fine for a racing car, but it's really
bad news if you ever drive on dirt roads.

In the old days of carbs and manual chokes, airflow was a big deal because
changes in airflow would translate into changes in fuel mixture.  These
days with modern fuel injection systems it becomes a big issue only at
high RPMs because the fuel injection system keeps the mixture correct.  If
the filter clogs up a little, you have to press the pedal down a bit more
to get the same power, but the mixture is precisely the same as if your
filter was not restricting anything, because it's a closed-loop system now.

THAT'S WHAT YELLING IS!

Well don't be so bloody lazy - you'll want us to buy it for you ship it and then
