Engineered For High Boost Stability And Thermal Resistance

The Fleece Performance FPE-34145 45 Degree CAC Boot is a premium-grade charge air cooler connection designed specifically for 2013–2018 RAM 6.7L Cummins applications, particularly in 2nd Gen turbo configurations. Constructed with a 4-ply aramid polyester-reinforced silicone, this boot is made to withstand elevated boost pressures and extreme underhood temperatures. The 2.75 inch inside diameter and dual-leg lengths, measuring 2.375 inches and 3.875 inches, provide flexible yet stable fitment for custom or performance setups requiring a 45-degree transition. Aramid reinforcement enhances tensile strength and resists ballooning or deformation under sustained pressure loads, a common failure point in factory rubber boots. Its smooth inner surface promotes uninterrupted airflow through charge piping, contributing to more efficient power delivery and turbo response. The high-grade silicone composition also ensures superior resistance to oil saturation, cracking, and heat aging. For tuned or upgraded diesel builds, this boot delivers a critical sealing solution that ensures your intake path remains reliable even under aggressive conditions.
