Hey there, fellow truck enthusiasts! If you’re looking to give your 2020-2023 Duramax L5P 6.6L a serious boost, check out this cold air intake. It’s designed to really open up airflow compared to the stock setup, which can feel pretty restrictive. You’ll notice the difference right away.
This kit comes with a fully enclosed airbox that does a great job of keeping dirt out and minimizing engine heat. Trust me, that’s crucial for maintaining performance. The snap-in lid is a game changer—no screws needed. Just pop it on, and you’re ready to roll. Makes installation and inspections a breeze!
One of the standout features is the silicone edge trim. It seals off unwanted heat and debris, which is a big deal if you want to keep your engine running smoothly. Plus, the air filter is massive and super efficient, ensuring you get better airflow while protecting your engine at the same time. You can choose between an 8-layer cotton cleanable filter or a dry extendable media, depending on what fits your style.
Now, let’s talk about the materials. Everything from the air filter to the coupler and seals is made with high-quality silicone. This stuff can handle heat up to 400°F without cracking, so you know it’s built to last. Unlike rubber, it won’t deteriorate over time, which is a huge plus.
When it comes to airflow, this intake has three inlet points, which means you can customize how much air you’re pulling in. There’s even an optional box plug if you want to seal off one of those inlets. But honestly, for the best performance, I’d recommend running it without the plug unless you’re in a serious heatwave.
And don’t worry about check engine lights—this kit is engineered to work flawlessly with stock calibrations or any tuning you might throw at it. The Mass Air Flow Sensor is properly mapped, so you can drive with confidence.
Features:If you’re driving a 2020-2023 Chevrolet Silverado or GMC Sierra with the Duramax L5P, this intake is a solid upgrade that’ll help your truck breathe better and perform at its best.
