Upgrade Your Boost Path With Strength That Lasts

If you’ve been pushing your 2013–2018 6.7L Cummins hard and relying on factory boots to keep everything sealed, it might be time for an upgrade that can actually handle the pressure. The Fleece FPE-34145 2nd Gen 45 Degree CAC Boot is built for those who demand more from their truck, more boost, more reliability, and fewer unexpected failures. This boot isn't just another piece of rubber, it’s a reinforced, four-ply aramid polyester silicone hose designed to take the heat and hold tight under serious boost. Whether you're running a 2nd Gen turbo swap or fine-tuning a custom charge-air system, this 45-degree elbow keeps your airflow smooth and leak-free. The precision sizing with 2.375 and 3.875 inch leg lengths makes it a perfect fit for setups that need a strong yet flexible connection. It's the kind of upgrade you install once and forget about, because it's designed to outlast and outperform your factory parts in every way. If you’re serious about reliability and performance, this is the boot you want under your hood.

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.
