Subaru Direct Injector Testing, Cleaning, and Resealing Service

Enhance your Subaru’s performance, reliability, and fuel efficiency with our Direct Injector Testing, Cleaning, and Resealing Service. Ship your injectors to LaCorte Automotive, and we’ll restore them to OEM precision through advanced GDI flowbench calibration and ultrasonic carbon removal.

What’s Included:

Comprehensive Testing
Each injector is electronically and hydraulically tested for flow rate, leakdown, spray pattern, and electrical pulse response — ensuring balanced fueling and factory-level performance.

High-Intensity Ultrasonic Cleaning
We use industry-grade ultrasonic cleaning and reverse backflushing to remove carbon buildup, varnish, and combustion residue that accumulate inside GDI injectors.

High-Quality Resealing
Every injector is resealed with new Teflon combustion seals, o-rings, and filters — ensuring proper sealing and long-term reliability under high-pressure operation.

Detailed Spec Sheet
You’ll receive a before-and-after test report displaying injector flow rates, spray patterns, and balance improvements, so you know exactly what was restored.
