Engine Protection & Filtration: Anyone can flow more air. The trick is to flow more air safely. K&N provides an optimal blend of high air flow, filtration efficiency, durability and dust capacity. 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, K&N tests air filters both in and out of the OE air cleaner ensuring proper fit and function. Their goal is to design air filters with the maximum possible airflow achievable while providing guaranteed engine protection. The Importance of Oil: A 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. Cleaning Instructions:   STEP 1 - APPLY K&N AIR FILTER CLEANER:Liberally spray K&N Air Filter Cleaner onto both sides of filter and allow to soak for 10 minutes to loosen the dirt. Do not allow cleaner to dry on air filter. STEP 2 - RINSE YOUR K&N AIR FILTER:Rinse off your air filter with cool low-pressure water applied to the clean side out in order to flush the dirt out of the filter. Continue to rinse the filter until all traces of cleaner are gone. It may be necessary to repeat steps 1 and 2. STEP 3 - DRY YOUR K&N AIR FILTER:After rinsing your filter, gently shake off the excess water and only allow filter to dry naturally. Do not apply oil until the air filter is completely dry. STEP 4 - APPLY K&N FILTER OIL:When using the air filter oil squeeze bottle found in K&N filter air filter recharger kit P/N 253381, apply K&N air filter oil evenly along the crown of each pleat. Allow the oil to wick for approximately 20 minutes then touch up any light areas on either side of filter until there is a uniform red color at all areas.
