04-05 6.6L GM LLY Duramax S&B Cold Air Intake

Make Sure It Fits

Is your vehicle a LB7 or LLY? 2004 could be either. Check the eighth digit of your VIN to find out. If it’s a 2 you’ve got a LLY and you’ll need this kit. If it’s a 1 you’ve got an LB7 and need the 75-5101 kit.

Engineered to outperform your stock intake.

Our one piece air box design features an integrated box seal that keeps out unwanted engine heat. The cooler the air, the greater the density, resulting in better performance.

Looks great, long lasting and can take the heat.

Premium silicone seals won’t tear or crack and can handle temperatures as high as 400℉.

Quick and Easy Install

Designed to fit better than the stock intake. You’ll be breathing easy in 45 minutes.
