Keeps oil really clean. Only problem that I have is it's not made in the united states.
Timothy Devine, Setauket, New York
Great first experience shopping with you guys. I am also a big fan of yours on facebook. Excellent service and excellent products. One reason I bought the product was also because it's made here in the United States.

Thank you,

Davide, La jolla, California
"On a recent trip to the United states, I purchased a FilterCharger® for my MX 5, and on the day of my return I installed it immediately. I can not recall any other product I've ever purchased that made so much a difference to performance for the money. I have looked at your competitors products and have driven cars with them installed. Upon learning more about your FilterCharger®, I thought I would give it a try. Well I'm very impressed."
