Toyota Lexus LS400 Replacement Fuel Injector 23250-50010/23209-50010

When your Lexus LS400 experiences idle instability, acceleration hesitation, cold start difficulty or noticeably rising fuel consumption, this usually indicates aging or worn fuel injectors causing poor atomization and unable to precisely control fuel spray. The injector’s normal function is to atomize fuel into fine droplets and mix with air before delivering to cylinders to ensure optimal air-fuel ratio, providing smooth power and efficient combustion. This product fits Toyota Lexus LS400 (UCF10/UCF20), OEM numbers 23250-50010 and 23209-50010. Use new seals and clean install holes; tighten to standard torque to prevent leaks.
