Dinan 16-20 BMW 330i/340i/430i/440i (F30/F31/F32/F33/F34/F36) High Performance Heat Exchanger

The Dinan B4x/B58 heat exchanger for the F2x/F3x chassis assists in mitigating these issues with a more robust core (48mm thick Dinan core vs. 27mm thick OEM core) that wields 78% more heat transfer surface area for improved cooling capacity. The significant increase in core thickness requires unique "L" shaped end tanks to be incorporated as well, which also contributes to the overall thermal mass (ability to absorb, store, and release heat) improvement beyond the OEM setup. With up to a 15&deg IAT delta recorded over stock the Dinan heat exchanger is ready, and able, to assist in extending your vehicles ability to deliver maximum performance time and time again for your driving enjoyment! F22/F23/F30/F31/F32/F33/F34/F36 Due to the enlarged core and unique "L" shaped endtanks minor modification to the plastic core stack shroud may be required with some factory configurations ( particularly those with the optional OEM hot climate heat exchanger). Consult the installation PDF for full documentation on what exactly that entails.

• Average of 8&deg reduction in IAT's with a maximum reduction of 15&deg over 15 successive WOT pulls
• Installation hardware included (inclusive of xDrive specific transmission oil cooler brackets)
• Reduces the tendency to heat soak / go in to limp mode
• 48mm thick Dinan cooler vs. 27mm thick stock cooler
• 78% more cooling surface area and volume than stock
• 100% TIG welded and pressure tested

Upgrade your BMW with the Dinan High Performance Heat Exchanger designed specifically for models including the 2016-2020 3 Series and 2 Series variants. Featuring a robust 48mm thick core, this heat exchanger offers 78% more heat transfer surface area compared to the stock unit, significantly enhancing cooling capacity during demanding driving conditions. The increased thermal mass, achieved through the unique "L" shaped end tanks, helps absorb, store, and release heat more efficiently, reducing heat soak and the risk of engine limp mode during high-performance situations. This upgrade is essential for drivers seeking improved engine cooling and consistent performance through extended periods of spirited driving or track use. The installation kit includes all necessary hardware, including xDrive-specific brackets for seamless integration. It’s important to note that due to the larger core size, minor modifications to the plastic core stack shroud may be needed, especially with certain factory configurations, such as those equipped with the OEM hot climate heat exchanger. Full installation instructions are available to guide you through the process. This heat exchanger has been pressure tested and TIG welded to ensure durability and reliability, providing peace of mind while maximizing your vehicle's cooling efficiency. Not only does it effectively lower intake air temperatures, with an average reduction of 8°F and peaks up to 15°F over stock during high-load testing, but it also helps prevent heat soak, maintaining optimal performance during intense driving sessions. Designed for direct fitment on various BMW models including the 340i, 330i, M240i, and 230i, this high-performance component is a valuable upgrade for enthusiasts looking to push their vehicles' limits. Whether for daily driving or motorsport applications, the Dinan heat exchanger enhances your vehicle's cooling system, ensuring consistent and reliable performance when it matters most.
