Subaru Port Injector Testing, Cleaning, and Resealing Service

Bring back your Subaru’s smooth idle, throttle response, and fuel economy with our Port Injector Testing, Cleaning, and Resealing Service. Ship your injectors to LaCorte Automotive, and we’ll handle the rest — restoring them to factory flow precision and spray balance.

What’s Included:

Comprehensive Testing
Each injector is flow-tested for electrical operation, spray pattern, leakdown, and flow balance to ensure even fueling across all cylinders.

Ultrasonic Cleaning
We use multi-stage ultrasonic cleaning and reverse backflushing to remove varnish, carbon buildup, and internal contaminants, restoring proper atomization and spray quality.

High-Quality Resealing
Injectors are resealed with new high-temp o-rings, seals, and filters to ensure leak-free operation and OEM-level reliability.

Detailed Spec Sheet
You’ll receive a complete before-and-after test report, including flow rates and spray pattern images, so you can verify your injectors’ performance improvements.
