Specifications

Add an additional +20 hp to your 2017-2019 Duramax. Or, combine with the Derringer inline tuner for a total gain of 81 hp. Beats stock and the competition. New over-sized filter element, largest in its class, protects engine and outflows competition. Enclosed housing keeps out hot, power-robbing engine air. More airflow increases the air-fuel ratio allowing the engine to run more lean, reducing soot output, decreasing the frequency between regens.

Why It's Better

Banks Ram-Air versus stock.

The factory air filter housing has little room for air to flow around the filter.

The Banks Ram-Air housing has a larger inlet and ballistic-shaped nose, which encourage the reusable air filter to freely inhale for more power.

Product is made solid. Easy

Product is made solid. Easy to install. Gave the truck a little more intake and turbo sound but not too much. Has large openings for more air intake.

Would recommend to anyone looking to get a little more power and response out of there vehicle, plus can't argue that it helps with fuel mileage.

Easy install. Way more air

Easy install. Way more air feeding into the cold side of the turbo. The box took a little fanagling to get it in place, both other than that it was super simple. It took a little extra time to get it delivered due to supply issues. Huge air filter, I can hear the turbo more thanks to no muffler or resonator...

Absolutely love it. I also

Absolutely love it. I also bought the Derringer, the Pedal Monster and the 5" exhaust and it was worth it. Track mode on the Pedal monster is really sensitive. You can't drive it in the city in track mode because the truck just wants to go.

Banks are engine people. In a world of companies making disparate parts, Banks engineers the entire engine, not just its components. The proof of Banks’ expertise is its list of national championships and world records as well as the biggest military engine contract of the century. Of all the possible options, the U.S. military chose the Banks D866T engine for its high performance and durability. With over 66 years of breakthroughs and patents in high-performance gas and diesel engine development —including turbocharging and drivetrain, Banks has no rival.
