One problem with the increased airflow, doesn't the MAF meter just readjust for it?

And if I had one I'd be worried about either using too much oil or not enough. I've been told that they can't harm your MAF but I know that's not always so. A Toyota Avalon owner had a brand new K&N dropin that must have been over-oiled enough that it set a code and couldn't get much over 50% calculated engine load at WOT, until I cleaned the MAF and switched to a WIX filter...code didn't come back and saw well over 80% calculated engine load at WOT on my scanner's datastream.

Maybe someday GreenFilter will come out with a P/N for our Yaris. Similar to a K&N, just a little different approach.
