The cost for an Amsoil air
The cost for an Amsoil air filter for a '99 Nissan Altima is $26.00. They are good for 4 yers/100,000 miles. It works out to about $9.53/year over it's lifetime.

And how long you had the same filter in your car and how often you clean it and how you clean it? |
I clean my foam filter every
I clean my foam filter every time I think of it, about 5,000 miles, and have a paper filter that I slip in when I'm cleaning it as with foam filters you wash it with soap and water, dry it, and re-oil it with high-tac filter oil, so it's best to have the filter out of the car for a few days.
I personaly like the idea of the foam, it has a few differnt layers, going from corse to fine, and I figure it must be doing a good job of getting grit out, as the car still has 185psi + or - about 5psi acrose all the cylenders, and it's the origonal engine with 221,000 miles, and have found that useing foam filters on my motorcycles leaves the carburators much cleaner, as I understand it, foam filters are not standerd because they cost a little more, amaricans don't like things that are washed, and reused (recycle your bottles, don't buy returnable) and there is less to mess up if you just replace the part with a new one. I can't tell exactly how much restriction it has, as I don't have a good way to compare it, the printing on the filter is gone now, but I think it was something like a True-Flow, only it doesn't look exactly like what they are selling now under that brand name. |

May have to experiment
I may do a small experiment to see what works -- it seems to be a lot like exhaust backpressure, which varies by car and isn't fully understood. All kinds of advice from the EPA on down to the filter manufacturers say to change the dirty air filter and get better gas mileage: read restriction. I might try a small trial this week to see what happens (depending on the weather -- lots of rain predicted). The current restriction is down to about the size of a quarter with air temps ranging (I really need a grille block) -- and I've maintained MPGs in the low-30's. It definitely requires more pedal pressure, which the auto-trans doesn't agree-with on really hot days and/or with the A/C running.
