AC Delco (A division of Cummins I believe) usually have a very well built, solid filter. As does Baldwin and Donaldson, in that order. When you buy the filter, don't be afraid to take it out of the box and inspect it. The pleats should be straight, the corrugations (if it has them) should line up (that's so the air filter doesn't collapse under load, and keeps the pleats separated so the filter lasts longer), the plastisol gasket should have no gaps or bubbles so you can have a tight seal, and the glue that holds the pleats together at the ends should be even and have no gaps in it.
I'll have to take a picture or two of a good filter because just describing it sometimes isn't enough for some people. I'm a "I'll believe it if I see it" kind of a guy myself, so don't just take my word for it.
Get reviews on the filters you plan to buy. Don't always believe what manufacturers tell you, K&N is a good RACING filter, nothing more, nothing less. It is not made for longevity of the engine.
