2K3, shouldn't that be more of a confession vs. a statement?
Dirty/clogged air filters not only harm fuel economy, they can starve the motor for air and that's not good.
I change my air filters in the box once a year (with every oil change).
I'm not concerned about the fuel economy nearly as much as I want to treat my motor to big gulps of fresh, filtered air so I can keep it happy for many, many years. :dance:
So, I change my air filter and pollen filter annually with the oil change. Since the air filter is only changed once per calendar year, I don't mind spending ten bucks more on a factory filter vs. an oil-based aftermarket unit.
