Extreme Duty EGR Cooler

Cummins ISX Gen 1  2003-2006

This is the strongest EGR Cooler available today. The TamerX EGR Cooler Lasts longer, works better, and is the only cooler made to last. This is not the cheapest cooler you can buy but absolutely the best. WHY! for one it is made in the USA. The design uses stainless steel tubing that is TIG welded by craftsman trained specifiaclly for this task. The tube design has proven itself to be the best solution. The TIG welded joint is much stronger than the brazed OEM Design that has been proven to fail.
