Mishimoto Performance Intercooler for 2017-2019 GM 6.6L L5P Duramax (Silver)

Maximize the performance and protect your 2017-2019 Chevrolet or GMC truck equipped with the 6.6L L5P Duramax engine by upgrading to the Mishimoto Performance Intercooler in a striking silver finish. High intake air temperatures are a common enemy of diesel performance, leading to reduced power and potential engine stress. This intercooler is engineered to provide superior cooling, ensuring your Duramax engine runs cooler and stronger, whether you're towing heavy loads or pushing the limits.

Key Features and Benefits:

  • Direct Fit for L5P Duramax: Designed for a precise fitment on 2017-2019 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD trucks with the 6.6L L5P Duramax engine.
  • Enhanced Cooling Performance: Features a massive 68mm thick bar-and-plate core, representing a 70% increase in thickness over the stock unit. This significantly boosts heat dissipation for a denser, more potent air charge.
  • Improved Airflow: The advanced core design reduces airflow restriction by over 64% compared to the OEM intercooler, allowing the turbocharger to breathe easier and respond more quickly.
  • Robust Construction: Utilizes durable, high-quality cast-aluminum end tanks engineered to withstand the rigors of high boost pressures and extreme operating temperatures, ensuring long-term reliability.
  • Larger Inlet/Outlet Ports: Increased diameter for both the intercooler inlet (by 6mm) and outlet (by 12mm) further optimizes airflow into and out of the core.
  • Bright Silver Finish: The polished silver finish provides a clean, high-performance aesthetic under the hood.

Invest in the cooling performance of your Duramax truck with the Mishimoto Performance Intercooler. Experience reduced exhaust gas temperatures, consistent power delivery, and enhanced engine longevity. Get yours today from GGCRACING!
