S&B Cold Air Intake for 2020–2026 Silverado / Sierra Duramax L5P 6.6L Diesel — 75-5136

S&B cold air intake kit 75-5136 for the 2020–2026 Chevrolet Silverado 2500 and Silverado 3500 6.6L L5P diesel.

The kit replaces the factory intake tube, filter and airbox. S&B's airbox is fully enclosed, so the filter is fed cooler air from outside the engine bay rather than sitting in under-bonnet heat, and it seals with silicone — the filter seal, coupler, lid seal and box plug are all silicone, which seals better than rubber and handles temperatures to 400 °F.

This listing is the Cotton Cleanable filter version. That filter is washable and re-oilable, so it's serviced rather than replaced. The same kit with S&B's Dry Extendable filter is part 75-5136D.

Applications: 2020–2026 Chevrolet Silverado 2500 and Silverado 3500 6.6L L5P diesel; 2020–2026 GMC Sierra 2500 and Sierra 3500 6.6L L5P diesel.

This L5P intake has three air inlets, and the optional box plug can seal one of them off.

Emissions: S&B does not print a CARB EO number on this kit's page. If the vehicle is registered in California or another CARB state, check S&B's current emissions listing for this part number before ordering.
