S&S Diesel Motorsport 6.4F-80SAC-SET – New 80% Over Injector Set for 2008–2010 Ford 6.4L Powerstroke

Upgrade your 2008–2010 Ford Super Duty with the S&S Diesel Motorsport 6.4F-80SAC-SET, a brand-new set of eight high-performance common-rail injectors engineered for increased fuel delivery and reliable power. These 80% over injectors provide substantially greater flow than stock while maintaining the precision and consistency the 6.4L Powerstroke’s piezoelectric system demands.

Key Features & Benefits

• 80% increased nozzle flow over OEM for greater fuel delivery, supporting higher horsepower builds and improved performance under load.
• SAC nozzle design with S&S’s proprietary honing process for clean, consistent orifice geometry and excellent atomization.
• Precision flow-matching: Nozzles matched to within 1% variance per set; complete injectors matched to within 3% variance (tested to OE standards using Viscor SAE-J967 at 40°C).
• Aligned injection rate shape and custom-matched internal build specifications (including piezo modifications) optimized for the increased nozzle flow.
• Built with industry-leading components and rigorously tested on advanced equipment so the set delivers consistent cylinder-to-cylinder fueling, smoother operation, and strong real-world results.
• Ideal for street, towing, and performance applications when paired with proper supporting modifications (tuning, adequate fuel supply, and airflow).

Fitment

• 2008–2010 Ford F-250 / F-350 Super Duty with 6.4L Powerstroke diesel

Notes: Sold as a complete matched set of 8 injectors. Core return is required. Appropriate tuning is strongly recommended for best results and longevity.

These new S&S 80% injectors give 6.4L owners a proven path to more fuel, better response, and the performance headroom many builds need—without compromising the quality and matching standards S&S is known for.
