Frequently bought together

Why it works

Flows 43.69% more air than stock

S&B built this intake to cut air restriction on the 2004-2005 Chevy / GMC Duramax LLY 6.6L. The fully enclosed airbox keeps engine heat and dirt away from the filter.

Extra inlet in the airbox floor

An additional inlet in the bottom of the airbox adds airflow. A large silicone fender seal keeps hot air out.

Big filter that protects your engine

The kit includes a large, high-efficiency air filter for better performance and engine protection. Choose 8-layer Cotton Cleanable or Dry Extendable media.

Clear lid for easy filter checks

The snap-in clear lid lets you see the filter at a glance. To service it, pull the lid by its tab and loosen the filter hose clamp.

Installation

Bolt-on with hand tools. Grab the manufacturer’s step-by-step instructions, or watch the install first. Stuck partway? Call real humans at (920) 249-7744.
