Built To Take The Heat And Hold The Line
The BD Diesel 1405221 intercooler hose is engineered for serious performance under pressure. It’s constructed with high-strength materials, using four to five layers of DuPont Nomex and Aramid fibers instead of cheap polyester, making it capable of withstanding up to three times its working pressure. This hose doesn’t just survive under stress, it thrives, even when placed near hot turbos or exposed to continuous high-boost conditions. Its 3-inch inner diameter is ideal for universal fitment in performance diesel and turbocharged setups, offering excellent airflow and structural integrity. Because it’s sold by the inch, builders can cut it to match exact layout needs, whether for a street-driven upgrade or a track-ready rig. BD Diesel designed it to meet the demands of aggressive tuning, high-flow intercooler systems, and tough driving environments. With a 12-month or 24,000-mile warranty backing it, this hose is as dependable as it is rugged. It’s a practical choice for anyone who doesn’t want to compromise between flexibility and strength.
