Description
Factory exhaust manifolds restrict flow on the 5.4L modular engine, costing you both power and efficiency. These JBA headers deliver measurable gains in horsepower and torque by reducing backpressure and improving scavenging—all with a simple bolt-on installation. Built from stainless steel, they resist corrosion and thermal stress while maintaining their performance advantage for years.
