AMS Performance Intake Manfiold for BMW M340i B58 3.0L Turbo Engine 2020+
As power climbs, so does heat in the BMW B58’s intercooler system. To keep the intake charge cool, you need an efficient way to move that heat out. The AMS Performance BMW B58 Intake Manifold is built for that job. Its twin core design pushes coolant through the system in a smarter way, which gives it stronger cooling than other options. The manifold also adds an easy way to run port injection. The flush-mounted -8AN fuel rail keeps fuel flow clean and direct. That means better combustion and more power. This setup is made to handle real numbers, not just talk.
- Rated for 1250+ HP with parallel air-to-water intercooler cores
- -8AN auxiliary fuel rail for expanded fueling options
- CFD tested for balanced airflow across all cylinders
- Angled port injection for cleaner fuel atomization
- 135% larger core area compared to OEM
- Three extra -4AN ORB ports on the plenum for vacuum sources
- Complete kit with all hardware, lines, and fittings included
Engineered to Win
The AMS Snailworks Engineering Team built the AMS Performance BMW B58 Intake Manifold to bolt right in. No cutting. No mess. It works with your factory A/C, power steering, oil filter cap, and everything else under the hood. If you ever want to go back to stock, you can do it with a few low-cost parts. This manifold is built to perform, last, and make installation simple. AMS spent hundreds of hours testing and refining it. We used advanced CFD software to shape the A356 T6 cast aluminum plenum and runners. The goal was clear airflow to every cylinder. The result is precise flow balance within 0.5 percent per port.
This isn’t just a part. It’s the result of real engineering.
Parallel Split Core Design for Optimized Coolant Flow
The AMS Performance BMW B58 Intake Manifold uses a parallel split core design that routes coolant from the center instead of pushing it through from one end. This keeps water pressure steady and improves flow, so heat gets pulled out faster and more evenly. Every cylinder gets cooler water, and it lines up with the coolest air hitting the farthest point of the intercooler. That pairing improves heat transfer across the entire core. The twin cores, rated for 1250+ HP, are tuned for both airflow and coolant flow. The goal is to feed the engine while still pulling as much heat as possible. AMS Snailworks Engineering balanced this by shaping the cores with specific fin densities, fin heights, and water passage sizes. This combination helps keep pressure drop low while pushing strong airflow and efficient cooling.
