At times, the short-lived 6.4L Powerstroke feels a little bit like the middle child of the Powerstroke name. Emerging before the design had been completely perfected but after most of the crippling issues of the 6.0L had been resolved, the 2008-2010 Super Duty diesels are capable, yet sadly overlooked workhorses. Fortunately, we here at Stage 3 have a lot of love for the 6.4L. We carry engine parts and upgrades from simple bolt-on intake systems to EGR fixes and even PCM tuning. We'll run through a couple of our favorite engine upgrades for this awesome truck to help you on your way with your own build!
