$PBHG President Michael Reed installed a series 23A Magnum Duel Cell System on a customer's 2006 Ford F-350 truck that is being used for hot shot deliveries. Other vehicles that these units have been installed on are a BMW X5, 2009 Ford F-150, and a 2002 Ford F-350. These HHO generators are all showing an average MPG increase of 26-30 %, and a reduction of 85% on emissions. Our customers have told us they are excited to see such great increases in fuel mileage, especially with the high cost of fuel today.
