Total Auto Parts likes that after establishing the base line horsepower numbers of a 2015 Chevy Silverado 2500HD 6.6L diesel in stock trim, a 2015 Chevy Silverado 2500HD 6.6L diesel was dyno tested with K&N diesel air intake on KN Filters in- house dynamometer,. the horsepower and torque gains were observed throughout the RPM range. The max estimated gain of 19.94 horsepower occurring at 2,950 RPM and the estimated peak torque gain of 19.75 lb- ft taking place at 2,850 RPM.

KN Air Intake 77-3087KP comes with a black metal topped K&N high-flow air filter and a heat shield.
