S&B’s newly redesigned cleanable cold air intake for the 2004-2005 6.6L Chevy/GMC Duramax LLY models features a large airbox with a huge inlet that feeds cool air directly to the filter – eliminating power-robbing engine heat.

  • Cotton, cleanable filter
  • 43.69% more airflow than stock intake
  • 99.52% efficient @ 612 CFM (ISO Coarse Dust)

Make Sure It Fits
Is your vehicle a LLY or LB7? 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

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?.
