The cure for airflow restrictions. The
stock LLY is riddled with airflow bottlenecks—including
the intercooler. PowerPack replaces them with free-flowing components
that dramatically increase intake airflow and air density and
expel exhaust with virtually no backpressure.

GM Duramax LLY
Colossal
power stays cool, sips fuel.
All that improved airflow is then balanced with Banks’
advanced CleanTune™ Technology for 41% more HP and 52%
more torque than stock, without adding black smoke. This is
load-hauling, hill-flattening constant-duty power that keeps
its cool. It’ll launch you from 0-60 mph 13 sec. quicker
and from 40-60 mph 8 sec. quicker when towing. And thanks
to the EconoMind’s fuel savings features, you’ll
get up to 19% more MPG, too. Sweet!
The
Banks difference? Engineering.
Forget mis-matched components. Run away from tuners that can
destroy your engine. Everything in PowerPack is engineered
to work together to maximize your engine’s power, efficiency
and durability. PowerPack honors your vehicle by safely living
within the limits of your engine and powertrain. Your Duramax
will run stronger and live longer!
All gains
