CSF 06-10 Silverado H.D / Sierra H.D 6.6L Turbo Diesel Heavy Duty Intercooler

CSF Heavy Duty Intercooler represents a significant enhancement for your 2006-2010 6.6L Turbo Diesel Silverado and Sierra HD models, combining superior engineering with robust construction to meet the demands of high-performance diesel applications. Designed specifically for heavy-duty use, this intercooler is built to withstand the rigorous conditions faced by Duramax engine owners who require reliable and efficient cooling under elevated boost pressures.

The intercooler features a heavy-duty bar & plate core construction, which provides a substantial increase in cooling surface area and volume compared to the original equipment manufacturer (OEM) tube & fin design. This translates into markedly improved heat dissipation and lower intake air temperatures (IATs), which are critical for maintaining engine performance, efficiency, and longevity. The core thickness of 1.625 inches (41mm) and a length of 20.5 inches (521mm) ensure optimal airflow and thermal management, while maintaining a precise fit within the vehicle’s engine bay.

Engineering Excellence and Durability

CSF has engineered this intercooler with a focus on durability and performance. The all-aluminum cast end tanks are pressure tested at 120 psi to guarantee maximum reliability in extreme boost environments. The 100% TIG welded construction enhances structural integrity, surpassing the brazed joints found in many OEM units. This meticulous manufacturing process ensures that the intercooler can endure the stresses of high boost levels without compromising its structural integrity or cooling efficiency.

The intercooler’s design also incorporates CSF’s proprietary thermal rejection powder coating, which improves heat dissipation by up to 15% compared to non-coated units. This coating not only enhances thermal performance but also provides a sleek, OEM+ aesthetic that complements the vehicle’s engine compartment.
