CAC Hose 2.75in I.D. x 6in long - Black

The CAC Hose 2.75in I.D. x 6in long in black is a critical component for any turbocharged or supercharged engine build. As a mechanic, you know that charge air cooler (CAC) plumbing demands precision—weak connections and poor-quality hoses lead to boost leaks that tank power and reliability. This silicone coupler is engineered to handle elevated temperatures and pressure cycles in your intake tract, connecting intercooler piping with a straight, hump-style design that fits tight engine bays and complex routing scenarios. Whether you're tuning a street car, prepping for forced induction, or repairing existing CAC piping, this hose delivers the durability you need for consistent peak boost.

Built from high-temperature silicone material, this CAC hose resists cracking and thermal fatigue that standard rubber tubing cannot withstand. The 2.75-inch inside diameter (I.D.) matches standard intercooler and turbo outlet sizes, while the 6-inch length provides flexibility in packaging without requiring multiple couplers. The hump profile—a subtle bulge in the hose wall—aids structural integrity under pressure spikes, preventing collapse during transient throttle events. Black color indicates premium silicone construction and UV resistance, protecting against sun exposure and maintaining flexibility across extreme temperature swings typical in boosted applications. This single-piece design eliminates weak points at seams and reduces installation complexity.

This CAC hose suits turbocharged and supercharged builds across domestic and import platforms—LS swaps, EcoBoost engines, Honda K-series forced induction, and Subaru STi tuning all benefit from reliable intercooler plumbing. Weighing just 0.59 lbs and measuring 6 inches long, it installs cleanly in tight underhood spaces without rerouting existing harnesses. Pair it with quality V-band or T-bolt clamps (sold separately) to ensure leak-free sealing at both ends. Mechanics and enthusiasts trust silicone CAC hoses for sustained boost levels and consistent dyno results—this hose is a no-compromise upgrade over factory rubber or budget alternatives that degrade under heat and pressure.
