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.

K&N is the best filter available - so good that it's used as the industry standard. No one can argue with the quality of your products.
Paul Robson, Elgin, United Kingdom
Brilliant product. Does everything it says on the box and is better than having a cone squeezed into the models engine bay. This product fits in smooth and fast it only takes a few bolts and your done its so simple .And it makes it sound more of a machine than a pussy cat.
