Sinister Diesel EGR cooler for 2003 Ford Powerstroke 6.0L Super Duty F-250/F-350 and Excursion offers a less-restrictive replacement to the factory cooler. It uses high-flow stainless tubing in place of narrow fins, is TIG-welded and pressure-tested to prevent leaks, and is designed to fit like the stock unit for easier installation without removing the intake manifold.
