Product Details

This listing is for a BorgWarner K04 Turbocharger Cartridge, part number 53047109907. This is a complete center housing rotating assembly (CHRA), meaning it includes the turbine and compressor wheels already balanced and assembled onto the shaft, ready to be installed into your vehicle's existing turbocharger housings. This part is designed as a direct replacement for the factory turbocharger found on specific Mazda CX-7 models. BorgWarner is a well-known name in the turbocharger industry, and this CHRA is built to meet the demands of forced induction systems.

The K04 designation indicates a specific size and performance characteristic within the turbocharger world, often associated with improved airflow and responsiveness compared to smaller factory units. This CHRA features robust construction, utilizing durable materials to withstand the high temperatures and pressures inherent in turbocharging. The precision balancing of the rotating assembly is critical for smooth operation and longevity, ensuring that the turbo spins efficiently without excessive vibration. When you're rebuilding or upgrading your turbocharger, a balanced CHRA like this one from BorgWarner simplifies the process, as the most complex and critical component is already assembled and ready to go.

Because this is a CHRA, you will need to transfer your existing compressor and turbine housings to this new assembly. It's important to ensure your original housings are in good condition and free of damage before installation. This part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
