Dinan High Performance Heat Exchanger for BMW 330i / M340i / 430i / M440i / 230i / M240i / Z4 2019-2026


Note: 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.

Overcome the limitations of the factory cooling system with the Dinan Performance Heat Exchanger for the F2x/F3x chassis, engineered for modified B4x/B58 engines. This essential upgrade combats heat soak during intense driving, preventing the power-robbing temperature spikes and ECU limp modes that plague the stock unit. With a massive 48mm core offering 78% more cooling surface area, it delivers significantly lower intake air temperatures—keeping your engine performing at its peak, pull after pull.

Key Benefits:

  • Sustains Peak Performance: Drastically reduces intake air temperatures (IATs) to prevent ECU timing pulls and power loss during aggressive or track use.

  • Robust Cooling Capacity: Features a 48mm thick core—significantly larger than the 27mm stock unit—for superior heat dissipation and thermal mass.

  • Prevents Heat Soak & Limp Mode: Maintains stable cooling under repeated hard acceleration, extending your vehicle's performance envelope.

  • Direct, Complete Fitment: Includes all necessary hardware for installation, with specific brackets for xDrive models to ensure proper transmission cooler clearance.

Detailed Features & Specifications:

  • Core Design: 48mm thick high-efficiency core vs. 27mm stock, with unique "L" shaped end tanks.

  • Cooling Improvement: Provides 78% more heat transfer surface area and volume than the factory exchanger.

  • Performance Result: Achieves an average reduction of 8°F in IATs, with up to 15°F reduction observed over successive WOT pulls.

  • Construction: Fully TIG-welded and pressure-tested for reliability and leak-free operation.

  • Compatibility: Designed for F2x/F3x chassis vehicles with B4x/B58 engines. Includes installation hardware and xDrive-specific transmission oil cooler brackets
