I haven't noticed any differnce in mpg gains with paper over the foam, but I like that I can wash my foam filter, re-oil it, and not have the cost or extra trip to the store to buy a new one.
Do you have a link where I can get one???
I used to have an Injen filter, it stayed clean but it let in too much air and my car compinsated with more fuel. Do these filters let in a lot more air?

I replaced the Prius filter

I replaced the Prius filter at about 45k miles. I kept it clean by using a shop vac to remove the dirt every 5k miles or so.

The Del Sol filter was clean when I bought it and 4k miles later it is still spotless. Im wondering if the left coast is dustier? Maybe it's the smog?

I doubt it's the smog. But I don't know what it is. Like 100 miles ago I had to flip the filter because the spot that absorbs the most air was black. The whole filter doesn't get dirty, only the spot where the air passes to go into the MAF

When you say black, do you really mean black or gray or what? Can you lighten the color with suction from a vacuum cleaner or does it stay the same color. I'm thinking it might be oil or something else being picked up at the intake.

The intake hose goes to the

The intake hose goes to the left headlight and sits behind it. So when air goes under the headlight it finds it's way to the intake hose. That spot behind the headlight is clean. The filter is gray. Can't be cleaned off with a a vaccum.

Intake Restriction vs. FE

OK, so I hear that replacing a dirty filter will improve FE; however, I have a restrictor device that blocks the flow of intake air considerably, and I seem to be getting better mileage due to forced, slower acceleration. Am I killing the potential for better FE on the highway?

a air filter is already a good restrictor. Performance air filters like K&N, Injen, and etc let too much air in and the engine compansates with fuel. Just use oem filters which have more restrction but they give the best results.

I was just looking for a filter that would filter out the same as the nissan filter but get dirty slower.

I want to start this reply by saying that I am NOT an Amsoil dealer but am what they call a "preferred customer." This means I get a price break but don't make any profit. That aside, I can look up a price for the new Amsoil filter if you would like. I have to eat supper now so I'll post some prices in a little while.

Really Complicated. Spend some time at the store counting the filter pleats of the different brands that are offered. The more pleats, the slower the filter will get dirty.
