## Description

Product Description The secret to our success lies in the unique characteristics of our filter medium that was originally developed by k&n all those years ago in the dust, sweat and tears of desert motocross racing. We just wanted to win races and stumbled on a cotton filtration technology destined to be great. Our high flow cotton gauze air filter is washable, reusable and built to last for the life of an automotive or motorcycle engine. K&n air filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to enhance its filtering capabilities and overall performance. From the Manufacturer view larger.K&N Replacement Automotive Air FiltersThe K&N High-Flow air filter is designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. Our automotive OE (original equipment) replacement air filters generally add 1-4 horsepower.

K&N air filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to enhance its filtering capabilities and overall performance. K&N Air Filters were created for an environment requiring maximum horsepower and enhanced acceleration in addition to protection from the dirt and dust of off-road racing. The result is an air filter that allows dramatically more air into an engine, is washable and reusable, and will protect your engine for the life of your vehicle.Designed to Increase Horsepower & AccelerationK&N High-Flow Air Filter Features & BenefitsWill NOT Void Vehicle WarrantyEconomical, a K&N Air Filter Will Last the Life of Your Automobile, Motorcycle, or ATVEasy to Install Dyno Chart example - 33-2360 with est. gain of 2.15 horsepower at 5695RPM on a 2009 Toyota Corolla 1.8Lview larger Results will vary depending on part number and vehicle.view larger Engine Protection and FiltrationAnyone can flow more air. The trick is to flow more air safely. In our opinion we hit the sweet spot – an optimal blend of high air flow, filtration efficiency, durability and dust capacity. We take filtration seriously. K&N Air Filter media has been tested both in-house and by independent labs using the ISO5011 test developed by the Society of Automotive Engineers. In addition we test many of our filters both in and out of the OE airbox ensuring proper fit and function. Our goal is to design filters with the maximum possible airflow achievable while providing guaranteed engine protection.The Importance of OilA K&N Air Filter is made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cotton’s microscopic strands. The nature of the cotton allows high volumes of airflow, and when combined with the tackiness of the oil creates a powerful filtering media that ensures engine protection. In contrast, most other media can not maintain the same balance of airflow and filtration throughout the filter's life without sacrificing one or the other. With a K&N Air Filter, there is no sacrifice. Never Replace Your Air Filter AgainHandmade in the USA and in the United Kingdom using only the finest materials, K&N OE Replacement Air Filters are washable and reusable. Regardless of what you’ve heard, it’s almost impossible to wash your K&N Air Filter too much. Inside our testing laboratory, we have washed and re-oiled one K&N Air Filter more than 100 times and it still performs up to specification. Depending on your driving conditions, we recommend cleaning your air filter every 50,000 miles.
