Dinan D780-0002 High Performance Heat Exchanger for BMW Engine Intercooler - B58

The Dinan High Performance Heat Exchanger is a direct replacement upgrade for 2016-2020 BMW 330i/340i/430i/440i models equipped with the turbocharged B58 engine. This performance intercooler significantly improves charge air cooling efficiency, reducing intake air temperatures and preventing heat soak during aggressive driving conditions.

Key Features:

• 78% greater cooling surface area and internal volume compared to the factory heat exchanger
• 48mm thick core construction versus 27mm stock unit for superior heat dissipation
• 100% TIG welded and pressure tested for maximum durability and reliability
• Reduces intake air temperatures by an average of 8°F with peak reductions up to 15°F over 15 consecutive wide-open-throttle pulls
• Eliminates heat soak issues and reduces the risk of entering limp mode during hard driving
• Includes all necessary installation hardware, including xDrive-specific transmission oil cooler brackets
• Direct bolt-in replacement requiring no modifications

This heat exchanger is essential for maintaining consistent power delivery on turbocharged BMW engines, especially for vehicles with performance software or other power upgrades. The dramatically increased core thickness and surface area allow the intercooler to absorb and dissipate heat more effectively, keeping intake air temperatures low for maximum power and reliability.
