A powder coated steel heat shield isolates the filter element and protects the K&N oversized chrome top air filter (RC-5046) from engine heat. Cooler outside air is drawn through the K&N air filter for an immediate power gain. The K&N air intake system replaces the factory intake tube and air box. The factory air box is restrictive in size and restrictive in air flow.

It takes less than 90 minutes to install this K&N air intake system to eliminate air path restriction and allow virtually free flowing air into your engine. K&N air intake systems also come with the famous K&N Million Mile Limited Warranty.

The high flow technology invented by K&N and made in the USA provides the best balance of airflow and filtration. The RC-5046 cone shaped air filter is also washable and reusable and can go up to 100,000 miles before cleaning is necessary.

The 57-2572 can be easily installed in 90 minutes or less and is backed by the K&N Million Mile Limited Warranty.
