The main product, the Upgraded EGR Cooler for the 6.0 was created from one part frustration and two parts genius: tired of replacing the Ford EGR coolers under their 12-month, 12,000 mile warranty, Ken decided to finally try something new.  Taking the best parts of the 'round' style EGR cooler design (a more reliable design than the 'square' style), he managed to build a square-style cooler with the round-style internal configuration.  The result is a successful product, sold to one happy customer at a time.
