Kia Direct Injector Testing, Cleaning, and Resealing Service

Enhance your Kia’s power, fuel efficiency, and reliability with our Direct Injector Testing, Cleaning, and Resealing Service. Ship your injectors to LaCorte Automotive, and we’ll restore them to OEM flow specifications using professional GDI flowbench calibration and ultrasonic cleaning technology.

What’s Included:

Comprehensive Testing
Each injector is electronically and hydraulically tested for accurate flow rate, spray pattern, leakdown, and electrical performance under simulated operating pressures.

Ultrasonic Carbon Cleaning
We use high-frequency ultrasonic cleaning and backflushing to remove combustion carbon, varnish, and fine contaminants from inside and around the injector tip.

High-Quality Resealing
All injectors are resealed with new Teflon combustion seals, o-rings, and microfilters to ensure proper sealing and durability under high fuel pressure.

Detailed Spec Sheet
You’ll receive a full before-and-after test report showing injector flow balance, spray uniformity, and performance improvements.
