S&B FILTERS COLD AIR INTAKE 75-5101 & 75-5101D | 2001-2004 6.6L DURAMAX LB7

Improve airflow into your 2001–2004 Chevy or GMC 6.6L Duramax LB7 with the S&B Cold Air Intake. Engineered to reduce intake restriction, this system flows up to 44.63% more air than the factory intake while providing the engine with a cooler, less restrictive source of incoming air.

The intake features a fully enclosed airbox designed to help isolate the filter from hot underhood air while protecting it from dirt and debris. A large, high-efficiency air filter provides increased filtration surface area while supporting the system's higher airflow capacity. Depending on the selected configuration, the intake is available with either S&B's 8-layer cleanable cotton filter media or dry extendable filter media.

S&B engineered the system to maintain proper Mass Air Flow (MAF) sensor operation with factory calibration and compatible tuning. An injection-molded MAF plate and foam sensor gasket provide a secure mounting surface and tight seal around the MAF sensor, helping maintain accurate airflow readings and prevent intake-related check engine lights.
