The Sinister Diesel EGR cooler for 2004–2007 Ford Powerstroke 6.0L is a drop-in replacement that uses high-flow stainless steel tubing and TIG welds instead of the stock brazed-fin construction to reduce the risk of internal brazing failure and coolant ingestion. It matches factory fitment for direct installation on 2004–2007 6.0L Super Duty and Excursion trucks, and is pressure-tested and finished in Cerakote Sinister Blue where offered.
