If you own a 2017-2019 Chevy Silverado 2500 HD with the 6.6L V8 Duramax Diesel Turbo L5P, you know how important it is to get the most out of that beast under the hood. That’s where the HPS Performance 827 Series air intake kit (Part # 827-674) comes into play. This isn’t just another bolt-on; it’s a game changer.

First off, the kit features a 4-inch mandrel-bent aluminum tube that really opens up the airflow. This means you’re not just getting a boost in horsepower and torque, but also a noticeable improvement in throttle response. You can feel the difference when you hit the gas—it's like the truck is finally breathing right. And the best part? It maintains a safe air-fuel ratio, so you don’t have to worry about tuning or triggering that pesky check engine light.

The heavy-duty powder-coated steel heat shield is a smart addition, too. It effectively blocks out the heat from the engine, ensuring that the air coming in is as cool as possible. Cooler air means better performance, and that’s something every diesel enthusiast can appreciate.

Installation is straightforward, thanks to the included manual that comes with clear pictures and step-by-step instructions. No need for any modifications—just swap out the restrictive stock air box and install the HPS setup. It’s designed to fit like a glove, so you can get back to the road or trail in no time.

The kit also includes high-temperature reinforced silicone hoses and industrial-grade 100% stainless steel t-bolt clamps. These components are built to last, standing up to whatever you throw at them, whether you’re towing heavy loads or just enjoying a weekend off-road adventure. And let’s not forget the washable and reusable HPS Performance Air Filter, which means less waste and more savings in the long run.
