Lexus Direct Injector Testing, Cleaning, and Resealing Service

Improve your Lexus engine’s performance, efficiency, and reliability with our Direct Injector Testing, Cleaning, and Resealing Service. Ship your injectors to LaCorte Automotive, and we’ll professionally clean, test, and reseal them to factory-level precision using advanced GDI flowbench calibration and ultrasonic carbon removal technology.

What’s Included:

Comprehensive Testing
Each injector is tested for flow rate, spray pattern, and leak integrity under real-world GDI pressures to ensure proper atomization and balanced performance.

Advanced Ultrasonic Carbon Cleaning
We use industry-grade ultrasonic cleaning and reverse backflushing to remove combustion carbon, varnish, and buildup that can cause misfires, hesitation, and poor fuel economy.

High-Quality Resealing
Every injector is resealed with new Teflon combustion seals, o-rings, and microfilters made from high-grade materials for long-term reliability.
