The BD Diesel Turbo Blanket, part number 1453521, is designed to optimize turbocharger performance and durability in heavy-duty diesel applications. Crafted specifically for Borg Warner T3 S300 Wastegated models, it also fits most similar-sized Garrett and Holset turbochargers, ensuring broad compatibility for fleet and performance vehicles. The blanket features stainless steel springs and built-in retaining clips, facilitating a seamless and secure installation. Its primary function is to reduce under-hood temperatures, which in turn helps maintain higher air density within the engine compartment, resulting in increased power output and overall engine efficiency.
This turbo blanket also helps to retain and normalize internal turbine housing temperatures. Lower turbine housing temperatures promote quicker spool times and more consistent boost response, especially under severe towing or high-performance conditions. By shielding hot components, it extends the lifespan of hoses, wiring harnesses, and coolant bottles, which are often vulnerable to heat degradation. The custom fit for Borg Warner, Garrett, and Holset turbo applications ensures a snug, effective installation that maximizes thermal management benefits.
Constructed with high-quality materials and featuring a stylized design with custom BD embroidery, this blanket offers both functional and aesthetic advantages. The product is backed by a 12-month or 24,000-mile warranty, providing confidence in its durability and performance. Designed for heavy-duty diesel engines, it plays a vital role in maintaining optimal engine bay temperatures, thereby enhancing power, reliability, and component longevity over the long term.
