The Banks Power 42249 Cold Air Intake for the 2017-2019 L5P Duramax will get rid of your restrictive stock intake system and allow your 6.6L Duramax to pull cooler, cleaner air into the engine and keep out hot, power-robbing air. The 42249 will add an additional 20hp to your L5P and gain a total of 81 hp when combined with the Derringer inline tuner. Not only will it increase horsepower, your L5P will see less regens, and run cooler when hauling heavy loads.
The Banks Ram-Air system uses a molded, streamlined filter housing to maximize the space available for airflow. The Banks 42249 housing has a larger inlet and ballistic-shaped nose, which allows air to move more freely into the engine to give your Duramax more power than the factory air filter housing. This system includes an oiled air filter that requires less service and fewer cleanings versus a dry filter system.

It was very easy to install and it didn’t take long everything fit just perfect it also makes the truck work a lot better as well five thumbs up from me thanks
Dirty ships Uber fast!
Super easy install and it’s a relief to know the truck can breath easier plus I don’t have to worry about extra pain of oil the filter nonsense.
This plus the derringer and their 5” monster is pricey stuff but well worth it IMO.
Also, Dirty hooked me up large on my order. They beat their own pricing even though they’re already the best prices in the country.
Shipped super fast!
Very easy install, around 30-45mins total.
Don’t listen to anyone else's nonsense about it tough to install/fit/manipulate into its home. They’re obviously just not mechanically inclined people.
With nothing in tow: it didn’t change the sound at all / you can’t hear the turbo any different than before. You might be able to hear the intake suck a bunch of air at low rpm right at take-off... and that’s a maybe, it my be all in my head because I’m over conscious and listening intently.
I haven’t had it installed long enough to comment on fuel mileage.
I chose not to reinstall the resonator so I’m excited to hear it once I hook up to my 5er and really get that turbo spinning.
It’s pricey but so far seems to be worth it.
