S&B Cold Air Intake for GM Duramax 2004-2005 6.6L LLY

Pricing: $269.00


S&B Cold Air Intake Kits are engineered to maximize the amount of airflow to your vehicle's engine. Tested to the ISO 5011 standard. S&B, however, takes it a step further using their extensive research and development to craft some of the best Cold Air Intake Systems on the market.

Factory intakes cannot compare to the airflow provided by S&B. Among their innovations is their custom air box. It's design keeps unwanted engine air & loose dirt out of your system while providing protection to your air filter. It's clear top, an industry first, allows for easy inspection.

All S&B Cold Air Intakes come complete with a premium S&B Air Filter, providing maximum airflow and engine protection. High quality cotton gauze is used to provide optimal flow and filtration to your vehicles engine. S&B Cold Air Intake Systems are made in the U.S.A. and are backed by a 1,000,000 warranty.

Amazing Airflow with Great Looks: At 642 CFM, this filter out flows stock by 50.6% while maintaining a 99.81% efficiency rating. Our intake with a dry filter flows 49.6% better than stock with a 99.78% efficiency.

Large Secondary Opening: Designed with a secondary inlet to lower the restriction level. A less restrictive intake results in better performance.

Easy Inspection and Maintenance: Knowing when to clean your filter is as easy as opening your hood and seeing when its time to service your filter thanks to S&B's signature clear lid. Custom molded for strength and to accommodate a huge filter. The lid shields the filter from engine heat and debris for better performance and longer filter life.

Advanced Engineering: In 2013, GM added a barometric pressure sensor, requiring us to head back to the drawing boards. We designed a new intake with a location for this secondary sensor so you get an intake that can meet the factory calibration or handle enhanced tuning.

Quality Parts: From the Cold Air Intake house to the screws that hold it in place, S&B is committed to giving you nothing but quality parts.

Make Sure This Fits Your Engine: Is your vehicle an LB7 or LLY? Check the eighth digit of your VIN to find out. If it is 2 you've got an LLY and are viewing the right kit. If it is 1 you've got an LB7 and this kit will not fit your vehicle.
