So what is an air filter? An air filter is a device that makes sure the air that is entering into your engine is filtered, and clean. Many air filters do this by filtering so much, they cause your engine to work extra hard to suck air through the filter. These air filtesr are not efficient, and generally don't do a good job of filtering the smallest of particles. The air filters we sell are the best brands available. Most of these air filters increase gas mileage. They increase gas mileage by allowing your engine to breath easier, and therefore allowing your engine to get the air it needs without working harder than it should. Since the air filter is more efficient, and allows more clean filtered air through, it generally increases power as well! We prove this to you by testing back to back a stock air filter and a K&N air filter on an Infiniti G35. You can read the full article here.
Facts You Should Know About Air Filters
We believe the primary function of an air filter is to deliver both high airflow and superior dirt protection. We design our air filters to provide minimum restriction allowing high airflow into an engine. In the vast majority of cases increased airflow will increase engine performance measured by horsepower and throttle response (torque). The performance benefits of maximum airflow are clear, compelling and well documented. That is why so many professional racers are willing to run expensive vehicles with no air filter, as opposed to installing a disposable air filter. They are seeking the additional horsepower and throttle response needed to win the race.
We design our air filters to provide superior filtration of the contaminants that can harm your engine while maximizing the airflow characteristics of the filter in question. The ability of an air filter to protect your engine is generally measured using a testing procedure developed by the Society of Automotive Engineers identified as the SAE J726 procedure. We subject a sample of our filter designs to this test procedure using Coarse Test Dust, which includes particles ranging in size from less than 5.5 microns to 176 microns. As a point of reference, a human hair is approximately 50 microns in diameter. The result of the above test procedure is a specific air filtration efficiency number. This efficiency number represents the percentage of test dust retained by the filter and thereby kept out of an engine. Our goal is to design our air filters to achieve maximum airflow while targeting overall filtration efficiency at 98%.
Because no two air filters are alike, the specific airflow and overall filtration efficiency will vary depending on the filter in question. However, you can rest assured that each air filter we sell, has been designed to achieve high air flow while providing superior filtration.
Both air flow and dirt protection are critical to engine performance. For this reason a consumer should always evaluate an air filter based on both its filtration efficiency and air flow capabilities. It is very easy to design an air filter that exhibits high airflow simply by reducing its filtration to unacceptable levels. As the “look” of a K&N air filter has become popular, many companies have begun offering products that copy that “look.” While imitation is said to be the sincerest form of flattery, our own testing has shown that many of these look-alike products do not provide a safe level of engine protection.

I ordered an air filer for my 2005 Toyota 4Runner V8 from Pro Street. The air filter came within 2 days, and I was pleased of the quick and easy installation. Definately recommended!
