The Ford F-350 EGR Cooler by Sinister Diesel for 2004-2007 models is designed to replace the factory EGR cooler loaded with potential failures due to internal brazing cracks. This square-style cooler is engineered for a direct fit, maintaining stock compatibility while preventing costly repairs that often arise from coolant leakage into the intake manifold, leading to engine issues like blown head gaskets.

Constructed with high-flow stainless steel tubing and reinforced by quality TIG welds, this EGR cooler offers superior reliability and durability. It is pressure tested and CARB EO# D-721 certified for legal compliance in all 50 states. The kit includes an installation kit with everything you need: water outlet connector hose, intake gaskets, o-ring kit, and turbo bolts. The enhanced design of Sinister Diesel's EGR cooler counters clogging issues common to stock units, and it seamlessly integrates with any performance chip, tuner, or the factory ECM without the need for additional modifications.
