2003-2007 F250 & F350 Sinister Diesel Oil Cooler Replacement Kit SDOC60

Protect Your EGR System

It's no secret that the 2003-2007 Super Duty has a less-than-perfect reputation for failing components. The EGR system in the 6.0L Powerstroke is often blamed for these issues, and rightfully so, but often-times the root cause of EGR failure is actually that pesky stock oil cooler, which becomes clogged with soot from engine coolant failing to pass through its tiny passageways. By replacing your faulty stock oil cooler with this replacement kit by Sinister Diesel, you improve engine oiling and cooling of EGR gasses, increase the life expectancy of your EGR cooler, improve the quality of oil running through your injectors, and also eliminate the notorious white smoke issue so many 6.0 owners have. Sinister Diesel analyzed common failure points of the stock oil cooler and improved them to minimize risk of failure, such as the expansion of the passageways where soot would normally clog and eventually lead to system failure. The Sinister Diesel Oil Cooler is made out of tig-welded billet aluminum that efficiently dissipates heat and has furnace-blazed connections to ensure reliable operation without leaks.
