Replace you factory faulty EGR cooler with this upgraded cooler from BulletProof. Countless owners of the 6.4L Ford Powerstroke have replaced their EGR coolers 2-3 times in the first 100,000. This is terrible on your wallet and also could cause damage to your engine. The Coolers from BulletProof are made 100% of stainless steel and feature a design internally all their own. The round tubes inside the cooler provide better flow and reduced thermal stress throughout the structure.
