AMS PERFORMANCE BMW B58 INTAKE MANIFOLD

ENGINEERED TO WIN

The AMS Snailworks© Engineering Team has designed the AMS Performance BMW B58 Intake Manifold to be a direct bolt-in install without hacking up your prized possession. The manifold is fully compatible with A/C, power steering, oil filter cap, and all other factory options, and is easily reversible back to stock with a few inexpensive replacement parts. The design of the new AMS Performance BMW B58 Intake Manifold positions it to be the best performing, highest quality, and easiest to install manifold on the market.

Our AMS Snailworks© Engineering Team has spent hundreds of R&D hours refining the AMS Performance BMW B58 Intake Manifold to be as efficient and effective as possible. Utilizing Computation Fluid Dynamics (CFD) analysis software, our team has been able to verify the geometry of our A356 T6 cast aluminum plenum and runners to optimize mass flow rate distribution to each cylinder. By taking this additional design step, our engineers have gone the extra mile and allowed for an equalization of airflow to within .5% to each individual cylinder port!

PROPERLY IMPLEMENTED PORT FUEL INJECTION

The 3.0L B58 engine found in various modern BMW models is a German engineering marvel. Unfortunately, the factory direct injection system is not conducive to making high horsepower or using ethanol flex fuel, which has led many owners to install port fuel injector spacers sandwiched between the cylinder head and factory intake manifold. During the R&D process of the AMS Performance BMW B58 Intake Manifold, our team knew they wanted to incorporate an optimally designed secondary port fuel injection solution as an option for customers.

By moving the injector ports onto the manifold runners themselves, we are able to properly angle injector nozzles directly at the intake valve and combustion chamber instead of at the wall of the intake runners where fuel can puddle. Our team went one step further with this concept by flush mounting the -8AN fuel rail to the manifold and pocketing the runners to allow the injectors to have an even more direct path to spray perfectly atomized fuel to the engine for maximum combustion efficiency.

PARALLEL SPLIT CORE DESIGN FOR OPTIMIZED COOLANT FLOW

The most significant design element of the AMS Performance BMW B58 Intake Manifold is our parallel split core design that allows us to route coolant from the middle of the unit instead of from one end to the other. This coolant flow routing reduces water pressure drop and increases flow rate at a given head pressure, meaning coolant can easily move through the system and expel heat efficiently. This split coolant flow design delivers consistently cool water to every cylinder by matching the coolest water (fresh from the heat exchanger), with the coolest air (furthest point through the intercooler), to maximize heat transfer across the length of the cores.

The 1250+ HP rated twin cores themselves have also been optimized for not just coolant flow, but for airflow throughput as well as reduced pressure drop. The AMS Snailworks© Engineering Team has struck a fine balance between airflow to the engine, and allowing the heat exchange process to cool that air. This is done by optimizing the dimensions of our proprietary parallel cores to allow for intercooler design elements like our custom spec fin densities on both coolant and air sides, fin height, and water passage size.
