I own an original Wildcat. I drove 4 hours to get it installed. On the drive back we measured the change in fuel economy and got a solid 20% improvement on my 2002 Dodge Caravan (hey i'm a family man!)  That was 2 years ago. That is why I remain invested. The TECH WORKS! The ORIGINAL unit does have it's leaking problems and my unit is no different. Very glad to hear they have re-designed it to eliminate some of these problems.
