Shipping was quicker than I expected. I have already noticed a difference in mileage. There is no doubt in my mind that this filter will pay itself off in three months. I would and have already recommended K&N filters to other drivers. I am very pleased with my purchase.

We are owner/operators with a 2009 International Prostar. We chose this air filter to help with the overall cost of replacement filters. We have the K&N air filters on all of our personal vehicles and love them also. Best INVESTMENT a truck driver could make!
