Product arrived very quickly, packaged very securely w/detailed instructions. Results were immediately noticed and I purchased the recommended servicing package from K&N so I could perform the maintenance when needed. Now I want to find a service provider to assist me with installing the complete cool air intake K&N system. Thanks for the product and prompt service.
