Ordered and received the air filter and free limited-edition Mustang Matchbox car. Being a limited-edition car, it was well worth the $55 and thanks for throwing in the free air filter. All kidding aside, I currently have 3 vehicles and this is now the 3rd one with a K&N air filter. I think your product is great. The fit is always right on, and being permanent (not throwing it in the landfill) is a big plus for me.

The size of the filter was perfect. Moreover, delivery is really fast, I received my package within 24 hours after the order. Also, K&N products are durable and they are good quality.

The filter arrived well packaged and included fitting instructions. The filter replaced the oem paper filter and fits the housing very well. Car does appear to breath better and rev a little easier, as promised. Also, good website ensures the correct product is chosen. Looking forward to many years of K&N use.
