Built To Take The Heat And Hold The Line

The BD Diesel 1405221 intercooler hose is engineered for serious performance under pressure.

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.

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.
