Looking for that proven performance boost, while maintaining all OEM piping? The K&N Panel Air Filter is the key! This filter is specifically designed for each different vehicle and will free your car from the air restriction that comes from an OEM intake filter. This K&N drop in filter maintains all of the OEM tubing and enclosures, while replacing the paper air filter in the OEM intake with a legendary K&N filter. K&N has always prided themselves with their 1 million mile warranty, so quality is never an issue with K&N. This filter is 100% washable and reusable, but depending on driving conditions cleaning will not be necessary before 50,000 miles. Go with the quality and name you can trust K&N.
