L5P Duramax New 150% Injector Set - S&S Diesel L5P-150-SAC-SET

When an L5P Duramax build moves past mild bolt-ons into serious turbo and horsepower territory, the stock injectors simply cannot deliver enough fuel. The S&S Diesel Motorsport L5P-150-SAC-SET answers that problem with a complete set of eight brand-new injectors sized at 150% over stock nozzle flow, built for 2017-2025+ Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks with the 6.6L L5P. Each set starts with new Denso L5P injectors, not remanufactured cores, and is then reworked in-house by S&S with SAC-style nozzles and a build spec tuned specifically to the 150% flow rate.

Big fuel is only useful if every cylinder gets the same amount at the same time. That is where S&S separates itself: nozzles are honed, flow-matched, and paired with injector bodies so the whole set behaves as one balanced system, helping keep cylinder temperatures even and combustion clean under heavy load.

Features:

• Complete set of eight brand-new S&S Diesel Motorsport injectors sized at 150% over stock nozzle flow
• Built from new Denso L5P injectors rather than remanufactured units
• Proprietary S&S nozzle honing process produces clean, consistent spray holes for better atomization
• SAC-style nozzles flow-matched per set using OE testing standards
• Complete injectors flow-matched as a set for even cylinder-to-cylinder fuel delivery
• Injection profiles (rate shape) aligned across the set so timing and volume stay synchronized
• Injector build spec custom-matched to the 150% nozzle flow rate for a truly integrated package
• Sold as a full matched set only; not available individually
• Fits 2017-2025 Chevrolet Silverado and GMC Sierra 2500HD/3500HD with the 6.6L L5P Duramax
• Backed by a two-year S&S Diesel Motorsport warranty

The 150% set is aimed at L5P owners running larger turbochargers and aggressive power goals who need substantially more fuel than the 50% or 100% sizes provide. These injectors are intended for off-road performance use and require custom tuning plus supporting fuel system upgrades such as increased lift pump supply, quality filtration, and adequate high-pressure pump capacity.
