AMS Performance Alpha Intercooler for W176 Mercedes-Benz A45 AMG / C117 CLA45 AMG / X156 GLA45 AMG

With 20 years of documented research and development in the forced induction field, AMS Performance has proven itself as the powerhouse in the automotive aftermarket. AMS’ award winning performance systems are what all others are measured by. Be the Alpha.

Whether you live in a hot climate region, enjoy drag racing, or long high speed pulls on airstrips the Alpha M133 AMG Intercooler will help keep your intake temps lower and maintain your AMG’s maximum power output no matter the conditions. Your Mercedes 2.0L turbocharged engine does not use the typical air to air front mount intercooler (FMIC) you may be used to. Like many modern turbocharged vehicles, the A Series AMG uses coolant to cool the intake air charge through an air-to-water heat exchanger and intercooler system. While this OEM system may be sufficient for a stock vehicle under ideal conditions, it can quickly become ineffective when dealing with additional heat from increased horsepower levels.

Through their testing, they found the factory Mercedes-Benz intercooler can also fail, internally. This failure allows for the air and water sides of the intercooler to mix. This mixture inside the factory intercooler can potentially damage your M133 engine. Not something you want as a performance enthusiast!

Replace The Failure Prone Stock Unit With A Motorsport Quality Upgrade

Over the years AMS has seen many factory intercoolers develop internal leaks which allow for the air and coolant to mix inside the intercooler core. This mixing of two separate systems can cause issues like lower boost output from the turbocharger, as well as the much more extreme scenario – liquid coolant entering your engine’s combustion chamber. For the core of the AMS M133 Alpha Intercooler AMS chose a motorsport quality core to rectify this potential issue. This high efficiency, dual pass core is much larger and dissipates heat quickly for maximum cooling. Through their larger design, added fluid capacity and drastically increased flow, your 2.0L M133 turbocharged engine benefits from over 10% reduced intake air temperatures (IAT), boosting your power output!

Increased Size for Maximum Cooling On Your Boosted Benz

By adding to the thickness of the OEM core you gain an extraordinary amount of added cooling by increasing efficiency. The Alpha intercooler core has an astounding 34% increase in volume over the stock intercooler! You gain an increased thermal efficiency over the entire intercooler system by installing the much larger Alpha M133 intercooler. The AMS Engineering Team actually designed the core with 22 fins per inch which allows for excellent airflow, and thus more heat transfer through the larger core.

Unparalleled Fitment Through Proper Engineering

AMS’ SnailWorks© Engineering Team set out to make this intercooler upgrade not only the most effective on the market but simple to install. By using the included Alpha mounting bracket, the intercooler neatly clamps into place so you or your trusted mechanic can install it quickly and easily. The intercooler simply slides into the factory location, connecting to the existing intercooler piping and water lines.

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.
We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at [email protected] with any inquiries.
