LB7 Gets Fresh Air
David from Willomet Motor & Fab upgraded his 2001 Duramax LB7 with a Banks Ram-Air Intake System to improve its towing capabilities for his 1985 Diesel Chevy Suburban project. While not seeking massive power gains, David reported a ¾ mile per gallon increase in highway fuel economy and a noticeable improvement in throttle response, particularly in the mid-range. He also noted the easy 30-minute installation of the bolt-on system.
