A Newer Powerstroke Deserves More Than The Same Old Pistons

A 2017-2019 6.7L Powerstroke is still a fairly new engine, so when one fails it is natural to want a replacement that is more than a like for like swap. This DFC Diesel KORE Series Speed of Air long block gives you that by pairing a remanufactured engine with Speed of Air Hyperformance pistons. The piston tops have precise, CNC machined dimples called turbulators, which DFC and Speed of Air say help the flame front burn closer to the cool walls of the combustion chamber and improve combustion efficiency. They say that can mean better fuel mileage, more torque and horsepower, and better pulling power, though results will vary by truck and how it is driven. The pistons also carry a thermal barrier coating on the crowns and an anti friction coating on the skirts. Around them you get the rest of the KORE Series build, including Rottler machined tolerances better than OEM, all new bearings, valves, and seals, and Total Seal gapless rings as standard. The engine arrives as a short block with the cylinder heads already on and a complete top end gasket kit, so much of the finishing work is covered. For an owner who wants a smarter piston at KORE Series pricing, this is the version to look at.

Turbulator Crowns And A Full Top End Kit On A Rottler Machined Block

The DFC Diesel KORE671719SOALB is a remanufactured long block built for 2017-2019 Ford F250 and F350 Super Duty trucks with the 6.7L Powerstroke. It uses Speed of Air Hyperformance pistons, which have patented turbulator indentations CNC machined into the piston top to exacting tolerances under ISO 9001 quality standards. Speed of Air says these indentations create a thinner, well attached boundary layer between the air fuel mixture, its flame front, and the combustion chamber walls, which raises combustion efficiency. The pistons are also coated, with a thermal barrier on the crowns and an anti friction coating on the skirts. The rest of the engine follows DFC's KORE Series process, machined on Rottler equipment to tolerances better than OEM, with all new rings, bearings, gaskets, seals, valves, springs, hardened seats, stem seals, and cast guides. It includes Total Seal gapless piston rings and improved gasket sealing in common leak areas. As a long block it is a complete short block assembly with the cylinder heads installed, and the page lists a complete top end gasket kit, plus gaskets and silicone, to finish the install. It does not include the front cover, rear cover, oil pump, upper or lower oil pan, oil pickup tube, oil cooler, rocker arms, or pushrods, and it is built in an ISO 9001:2015 certified facility with a 1 year, unlimited mileage manufacturer warranty.
