AMS PERFORMANCE 2019+ BMW M340I B58 HEAT EXCHANGER(AMS.51.02.0001-1)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 BWMs 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

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.

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.

Awesome, portable room divider for larger rooms
Color: Black, Color: Black
I chose this room divider to use in my son's room that also serves as my home office! It is 72" x 72" in size, so it truly blocks out the other side of the room for optimal privacy. Once it's assembled, it's mildly sturdy - as long as you can bet both ends with the "feet" in line with the ground. I wish that the framework poles had more of an interlocking system so that the divider was easier to erect. I assembled this on carpet, so I had some issues getting the divider to stop moving. It takes a lot of work to set up, as it is massive, so definitely have someone help you. I would suggest adding weights of some sort to the feet of this divider to keep it from shifting. I ended up leaning mine against a bookcase shelf so it wouldn't lean. All and all, this is a great product if you are looking to make a room multipurpose.

As described
Color: Black
Light weight, easy to put together and you can disconnect the ends and just roll the whole thing nice and tight for quick out of the way storage. Pretty sturdy, doesn't fall over if you bump into it, you could use it outside but if there's a lot of light you can see through a tiny bit if you're really close but I only tested this indoors so not sure about patio types
