道奇克莱斯勒5.7L V8 喷油嘴 53032713AB 06-09年原厂替换

This replacement injector matches original factory standards, using a precisely machined steel valve body and corrosion-resistant seals; tested on a bench for durability and stable performance under high temperature and high pressure for 5.7L V8 engines. OEM number 53032713AB; fits 2006-2009 Dodge and Chrysler models as a direct replacement. Functionally, it precisely controls fuel injection to ensure proper air-fuel ratio, preventing idle roughness or weak acceleration. Installation difficulty: medium; remove intake manifold, replace seals, and torque to specification; technicians with strong EFI experience may perform it themselves.
