If you're looking to boost your Duramax's performance, the 3 inch Max Flow Bridge is a solid upgrade. I’ve had my hands on this piece, and let me tell you, it’s a game changer. The precision casting and CNC machining ensure that it fits like a glove every time, which is crucial when you’re trying to squeeze out every bit of efficiency from your engine.
One of the biggest problems with the factory setup is its restrictive nature, and it’s notorious for those pesky boost leaks. This bridge tackles that head-on, improving airflow and overall performance. Plus, it comes with a 2.25 inch boot that pairs perfectly with the factory cold side, making installation a breeze.
This upgrade is compatible with the LLY Duramax models from 2004.5 to 2005 (just check the 8th character of your VIN to confirm the engine code). The 10th character will tell you the model year, so keep that in mind when you’re checking your rig.
When you get the kit, it’s not just the bridge you’re getting. You’ll find a bunch of components that make the whole process easier:
It fits a range of vehicles, including:
In short, if you want to get rid of those factory restrictions and really let your Duramax breathe, this Max Flow Bridge is worth a look. It's made for those who want to push their trucks a little further without the headaches of leaks or poor fitment. Trust me, your engine will thank you for it.
