Thank you so much for addressing my issue with my K&N Air Filter. Your customer service department is fast and thorough and my issue was delt with quickly. As for installation it was a breeze. Cleaning the filter is quick and easy. I live in the high desert of California and wind is a big factor. I clean my filter every ninety days. It takes me about an hour and a half from start to finish. The drying process takes the most time as I let it dry naturally. For me this product is cost effective and I'm confident it does its job as intended. Thank you for a great product.
