I like the product, and am hopeful I will see some improvement in gas mileage, etc. And will save some added costs versus replacing with more conventional filters over the years. (Too early to tell, though, about mileage. Only put in about two weeks ago, and all my driving virtually in town to date.) Thanks for the product and the good follow-up service!
