S&B 75-5075 Cold Air Intake with Oil(Cleanable) Filter for the 2015 GM Duramax 6.6L LML
Diesel engines consume air at a much higher rate than most gas vehicles. The speed of air flow is referred to in cubic feet per minute (CFM). The higher the CFM, the more difficult it is to stop the contaminants from reaching the vehicles engine. S&B designed a filter specifically targeting the diesel marketplace using 8-layers of cotton, a proprietary oil formula and 30 years of experience making filters. The result is a Performance Air Filter that greatly improves the air flow while still protecting your engine. Airflow Rating: Flows 41.7% Better than the Stock Intake. Efficiency Rating: 99.68% Efficient @ 653 CFM (ISO Course Dust).
