Cummins X15 66MM Performance Series VGT Turbo w/ Calibrated Actuator (2017+)

Cummins X15 Performance Series 66MM VGT Turbocharger with Calibrated Actuator (2017+)

Don't spend thousands more at the dealership for a replacement turbo. Upgrade your Cummins X15 with a premium, brand-new aftermarket Performance Series VGT turbocharger from Momentum Worx.

This is not a remanufactured turbo—it's a completely new, premium aftermarket turbocharger built with a 66mm billet aluminum compressor wheel, the latest-generation internal components, and a brand-new electronic actuator that is professionally installed and calibrated before shipping.

Every turbo also includes a complete installation kit with the necessary gaskets, seals, and mounting hardware, giving you everything needed for a hassle-free installation.

Whether you're replacing a failed Performance Series turbo or upgrading from an Efficiency Series engine, this turbo delivers increased airflow while maintaining factory drivability and bolt-on fitment.

Upgrade Your X15 the Right Way

Cummins offers the X15 with two primary turbo configurations.

Efficiency Series

• 62mm compressor wheel
• Designed for maximum fuel economy
• Rounded compressor wheel profile
• Lower airflow capacity

Performance Series

• 66mm billet compressor wheel
• Designed for higher horsepower applications
• Straighter compressor blade profile
• Greater airflow (CFM)

This turbo is a direct replacement for factory Performance Series engines and is also an excellent upgrade for Efficiency Series trucks looking for improved airflow.

The larger 66mm compressor wheel moves significantly more air than the factory 62mm wheel.

More airflow doesn't necessarily create more boost pressure—it creates more boost volume (CFM), allowing the engine to breathe more efficiently and support higher power levels.
