I will try and snap some when mine comes in next week.
Not trying to pick any power, but I'll never have to replace this filter ever, and for $46 shipped is not a bad investment IMO.

I guess that is another way to look at it. I agree. Clean it every 5k or so and you will make your money back and then some.
You may want to save an old filter and put it back in. If you take your care into the dealer with a non OEM they may blame it for any issues or say you voided the warranty. That's why I won't get another chevy
Magnuson/Moss act - Limitations if you damage something you void the warranty. If a bad dealer repair center deceides to say you put in an air filter that has oil in it and then claims it damaged a sensor or something else you have to disprove it. I know I have had to deal with it before.
You'd have to be a bumbling idiot to hydrolock an engine from applying too much oil to an air filter.
I'd rather put money in to wheels and suspension items that you can actually feel and get your money's worth.

No oiled gauze will ever filter as good as a paper filter.

Theres no way to dyno a filter. Most dyno's vary 2-3% each run, which is about 2-3 hp in a fit so theres no way to tell if the filter was the cause for the change in numbers or was it just variation in the dyno.

Here are the pics of the K&N installed:

K&N side pic which is a lot thinner than stock:

K&N installed:

Removed top chamber lid for extra air flow:

The K&N fit great as it should. I removed the top of the first chamber box which is held on by two screws. In the box, in the bottom left corner is a small opening that can now be used to pull extra air in instead of redirecting air which acts as a intake silencer. With that top removed the car now has a SMALL but noticeable growl under hard acceleration. The opening is very small and far away from the engine that I am not to concerned about any hot air being drawn in (no more than an open element aftermarket intake would).
*Just a side note: The MAF sensor is housed in the upper air box of the filter housing so handle with care.
For $50 bucks not a bad deal and I'll never have to replace it. I don't expect any major power gain, but I'd be happy with a 1 MPG gain. The Fit is a very efficient car already I'm just helping her breathe a little easier now.
