Brian Upshaw, Arizona
Filter came soon after ordering and was the exact part that I needed for my 2006 Mercerdes C230. I will be getting the air filter and cabin air filter when it is time to perform the service. I only run K&N filters in my vehicles and have always been pleased with the performance and ease of use.
