Unlimited Diesel Performance Stage 3 Powerstroke Fuel Injectors
These are the ultimate towing/street/strip Stage 3 Powerstroke fuel injectors by Unlimited Diesel with 238cc and either 80% or 100% Nozzles! These injectors are capable of 500 RWHP, but can also be detuned to tow heavy loads with EGT’s less than 1250*F sustained! This is a great choice for someone who has installed an upgraded turbo. Even with the size of these diesel fuel injectors, dual high pressure oil pumps are still not a requirement with proper tuning. Head studs are recommended if you are planning on running over 40 psi of boost. Fuel pressure should be checked also to ensure at least 60 psi. Custom tuning required for optimal performance.
