"Our J726 trials were conducted at an independent testing facility in the upper midwest. The tests compared Motorvator, K&N, Accel, Fram, and AMSOIL products. The results? AMSOIL proved vastly superior to the competitors' air cleaners as the only air filter to consistently score high marks in all three vital areas of airflow, efficiency and capacity.
The AMSOIL 2-Stage Air Filter traps airborne dust with 99% efficiency; it holds an incredible 281 grams of contaminant (that's over half a pound); and it outlasts the competition. It performs two to four times longer than the others. That's why AMSOIL can confidently recommend a 25,000 mile/1-year service life. And the 2-Stage is actually re-usable, with proper cleaning and re-oiling.
How does AMSOIL do it? Two different densities of lightly oiled polyurethane foam surrounding an expanded metal cage, precisely assembled by careful craftsman in AMSOIL's own manufacturing plant- that's how!"

K&N filters are a great mod... for a vehicle that can benefit (performance minded). I don't believe a vehicle designed for family utility is that vehicle.
Those grocery store parking lot drag races can be pretty intense though.
Just my 2 1/2 cents worth.

In the above quote from AMSOIL's website, AMSOIL says they make their own filters - "precisely assembled by careful craftsman in AMSOIL's own manufacturing plant". Are you suggesting that this is a lie?
