Alpha Performance Mercedes-Benz 5.5L BiTurbo Primary Heat Exchanger Upgrade

Whether you live in a hot climate area, enjoy long spirited drives in the mountains or long high speed pulls on airstrips, the Alpha Performance BiTurbo Primary Heat Exchanger Upgrade will help keep your intake temps lower and maintain your AMG’s maximum power output no matter the ambient conditions.

The 5.5L BiTurbo engine does not use the typical intercooler you may be used to. Like many modern turbocharged European vehicles this V-8 twin turbo engine uses coolant to cool the intake air charge through an air to water heat exchanger. While this method works well it can quickly become heat soaked, robbing horsepower.

Eliminate A Big, Power Robbing Restriction

We found through testing, the factory Mercedes-Benz center heat exchanger was very flow restrictive on the water side. This was hurting the heat rejection of the water side of the intercooler – causing less efficiency and choking up the power output of your M157 engine.

Motorsport Quality Upgrade For Your Boosted Benz

For the core, we chose a motorsport quality heat exchanger core. This high efficiency, dual pass core is much larger, featuring an additional 19 tubes (61 vs 42 stock) dissipating heat quickly for maximum cooling. Through a larger design, added fluid capacity and drastically increased flow, your 5.5L BiTurbo engine benefits from reduced intake air temperatures (IAT) boosting power output.


Larger CAD Designed Inlets And Improved Flow

While the coolant inlets that mate to the Alpha CNC billet end tank use the factory hose fittings, we made the inside diameter larger to increase the flow rate. The inside of these fittings flare out, creating a nice flow path for the water.

Unparalleled Fitment Through Proper Engineering

Our Engineering Team set out to make this heat exchanger upgrade not only more effective, but simple to install. It fits just like stock without any cutting or drilling. By using the factory lines and mounting points, the core simply slides and locks into place with no need for modifications. You don’t get a cleaner installation than that!

Compatible With Alpha Performance Packages and Boost Cooler System

If you desire further boost intercooling with an Alpha 7 or Alpha 9 package, this Alpha Heat Exchanger is compatible with our full Alpha Boost Cooler System (E63, CLS63). This system adds an additional cooler, pump and reservoir for the ultimate in cooling ability.

Great little watch for the money
Color: Brown/Brown/Natural, Color: Brown/Brown/Natural
I've just received the watch, so I can't comment on the durability. Hopefully it lasts a long time, because I really like this watch. My first impression of the watch was that it was a bit smaller than what I'm used to wearing. But when I put it on, it seemed like a good fit. The band looks great and feels pretty comfortable. I like the color of the band, and of the watch face itself. Even with my older eyes (56 years), I can easily read the time. The date, not so much. It's pretty tiny. Setting the time and date was pretty simple. And even though I knew this watch had it, I stumbled upon activating the Indiglo feature by accident. It's pretty cool, btw. Some people have commented on the ticking. The environment in which I wear the watch is never completely silent, even at home. I have to put the watch pretty close to my ear to hear it, and I have good hearing. When I do hear it, it's actually a pleasant sound to me. To sum it all up, I love this watch! I actually do a little watch collecting. This is by far the least expensive watch I own. And now, the one I'll wear the most.

Loud but one of my go-tos
Color: Gunmetal/Black/Green
I have young kids so a nice watch is always a risky game to play. This one is awesome, discreet, tough and looks awesome on a black nato strap. You can hear the ticking though when it’s really quiet. I tune it out but some might have an issue with it.

Bought a "Used like new" watch. Doesn't keep time
Color: Black/Black/Black/Fast-Wrap
I've had this for a few weeks. Since then, it's lost about 30 seconds. I'm not sure if it's this specific unit that has the issue or the mechanism itself. It's a shame because it's a killer looking watch.
