Why Choose a Genuine Garrett Turbo?

The Caterpillar ACERT twin-turbo system relies heavily on proper turbocharger matching. Installing the correct Garrett high-pressure turbocharger ensures:

• Factory boost response
• Proper turbocharger staging
• Reduced exhaust temperatures
• Improved fuel efficiency
• OEM drivability
• Maximum durability

Many aftermarket replacements simply cannot match the engineering and calibration of the original Garrett unit. When reliability matters, genuine Garrett remains the benchmark.

The Role of the High Pressure Turbo

On the Caterpillar C13 ACERT engine, the high-pressure turbocharger is responsible for generating boost during lower engine speeds and transitional load conditions.

This helps provide:

• Improved low-end torque
• Faster acceleration
• Reduced turbo lag
• Lower exhaust gas temperatures
• Improved overall engine efficiency

When the high-pressure turbo begins to fail, symptoms often include excessive smoke, sluggish acceleration, low boost pressure, elevated EGTs, and poor fuel economy.
