invest in a K&N air filter

Based on my calculations, my '05 4 cyl altima got 8% better fuel economy after putting it in.

Highly unlikely. There are other factors that are always in play, that are seldom accounted for. The throttle plate is the point of largest restriction in flow.

Can we see your calculations? What was the before and after testing??

I should have tested mine ABA before I threw away the paper filter. I grabbed a K&N for the savings, not the claimed mileage or hp increase. I already own it, so I am keeping it, but I probably would have passed on it if I know what I know now.

Are the folks at K&N so desperate they resort to spamming forums? I guess these are the tasks they assign to the marketing interns.

Maybe he drove the car 20k miles down a dirt road with the OE filter, drafting someone.
