I have my doubts too. It seems high considering the engine size. There is also the fact that the air filter is oversized to begin with. If you look at the cross reference on the K&N website, the same filter is used on about half of Mitsubishi's fleet including the EVO which pushes just under 300 hp. However, they do own their own dyno, and have tested all their other mods that they make...
I just installed mine a few days ago. Didn't feel any SOTP difference. It sounds maybe slightly louder at WOT. My mileage prior to the install was around 21.8mpg. It made a slight mileage difference (increase) in my 1998 4-Runner. Not seeing the same gas mileage, but that's probably due to my more aggressive driving after getting more accustomed to this car.

At least for my US model, that size is not correct. I'm measuring 9.875" x 4.75" for my filter size. The closest is this here, model number 33-2211 http://www.knfilters.com/search/prod...x?prod=33-2211

Don't want to rain on anyone's parade:
Unless a filter flows more CFM you aren't getting anything out of it. The laws of physics apply to the K&N, just like the cheaper stock filter.
I doubt the K&N has a higher CFM (in practice/reality/real world application) than stock. It's nice that they're reusable, however often after 'cleaning' they are so oil saturated they actually are more restrictive.
A waste of $$ IMO.
Get fresh OEM-type paper elements every oil change and you'll be good-to-go.
P.S. changing (i.e., replacing the used one) the air filter to a 'basic' (albeit new & clean) FRAM on my 1998 Ranger netted a 3+ MPG increase.

Amen brother... so many people have wasted so many dollars on K&N filters. They are good for race cars... pretty much it.
