2019+ BMW M340i – w/ B58 3.0L Turbo Engine (Incl. G20 and G21 chassis) | Various Unconfirmed B58c BMW Models (See below for further information)

As horsepower numbers rise, so do temperatures through the BMW B58’s intercooling system. In order to cool down that hot intake charge air coming from the turbocharger, you need a highly efficient heat exchange process which is where the AMS Performance BMW B58 Intake Manifold comes in. With our unique parallel twin core design, we are able to route coolant flow in the most efficient way possible giving us unparalleled cooling efficiency over the competition. The AMS Performance BMW B58 Intake Manifold also provides for an auxiliary port fuel injection solution by way of its flush mounted -8AN fuel rail, giving the atomized fuel a nearly unimpeded path to the combustion chamber. Our superior engineering yields superior results.

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.Includes

Application(s):

2019+ BMW M340i – w/ B58 3.0L Turbo Engine (Incl. G20 and G21 chassis)

Whether you live in a hot climate region, enjoy drag racing, or long high speed pulls on airstrips the AMS Performance 2019+ BMW M340i B58 Heat Exchanger will help keep your intake temps lower and maintain your BWM’s maximum power output no matter the conditions. Your 3.0L turbocharged B58 engine does not use the typical air to air front mount intercooler (FMIC) you may be used to. Like many modern turbocharged vehicles the M340i uses coolant to cool the intake air charge through an air-to-water heat exchanger. While this method may be sufficient for a stock vehicle under ideal conditions, it can quickly become heat soaked, robbing horsepower.

  • CNC Machined 6061 T6 Billet Aluminum End Tanks
  • Plug and Play Installation
  • OEM Style Fitment Features for Secure Mounting
  • 122% Added Fluid Capacity Further Improves Thermal Stability
  • Motorsport Grade Dual-Pass Heat Exchanger Core
  • 54% Increase in Core Volume over Stock
  • Designed with CAD software for Ultimate Performance and Fitment
  • 5mm Tall Louvered Fins for Exceptional Cooling Efficiency

Engineered to Win

Our SnailWorks© Engineering Team set out to make the AMS Performance 2019+ BMW M340i B58 Heat Exchanger upgrade not only the most effective on the market but also the easiest to install. Our team has spent countless R&D hours painstakingly designing the heat exchanger via Solidworks© Computer Aided Design (CAD) software as well as conducted rigorous on-track testing. It fits just like stock without any cutting or drilling. By using the factory hoses, clamps and mounting points you or your trusted mechanic can install it quickly and easily. The core simply slides in, locking into the factory mounts, and gets connected to your existing factory coolant lines. You don’t get a cleaner, more simple installation than that!

The most effective way to increase thermal transfer is by increasing the overall surface area of the exchanger. This is why we have packed in a 54% increase in core volume over the tiny OEM unit, lowering the amount of time for heat to be extracted from the system. Additionally, by increasing the fluid volume of the entire system by nearly half a gallon our heat exchanger acts as a large fluid reserve to increase thermal capacity so that coolant temperatures are kept low and stable. With a 122% increase in coolant capacity over stock, it increases the thermal stability in your BMW’s intercooler system which keeps horsepower-killing heat soak at bay.

The Difference Is In The Details

The most important part of an air-to-water intercooler system is the heat exchanger core. Skimping here could mean the overall performance of an ‘upgraded’ system might be worse than stock!  This high efficiency, dual pass core allows coolant to make two passes through the heat exchanger before exiting, dissipating heat quickly for maximum cooling. Our team tested numerous core types with varying sizes and features to guarantee the highest performance possible. The AMS Performance 2019+ BMW M340i B58 Heat Exchanger utilizes a 5mm tall louvered fin which allowed for the best heat transfer and coolant tube count of any fin design we tested. Additionally, this louvered design allows for extra surface area which promotes more efficient heat transfer out of the core.

Focusing on component design and materials selection is crucial during product development, and is why we have utilized top tier materials as the foundation of the AMS Performance 2019+ BMW M340i B58 Heat Exchanger. The end tanks are manufactured from billet 6061 T6 aluminum, which is then precision CNC machined for a perfect fit — every time. Because we are using billet end tanks, our team was able to integrate OEM-style fitment features which allow the heat exchanger to lock into place, just like BMW intended. These features are built into our billet end tanks and would be difficult to recreate otherwise, allowing our kit to stand above the competition.
