Optimize your vehicle's performance with the Dinan B4x/B58 heat exchanger designed specifically for the F2x/F3x chassis. Unlike the factory counterpart, this heat exchanger is engineered to excel under the demands of modified builds.

Say goodbye to the limitations of the stock heat exchanger, which struggles to handle intense driving conditions. It's common for the factory heat exchanger to falter when pushed to the extreme, resulting in soaring Intake Air Temperatures (IATs) that trigger the factory ECU to intervene by pulling timing and reducing power output. This safety measure prevents overheating, but it hampers your driving experience.

Enter the Dinan solution: a superior B4x/B58 heat exchanger boasting a robust 48mm core, starkly contrasting to the meager 27mm core of the OEM version. This substantial core enhancement translates to a remarkable 78% increase in heat transfer surface area, ensuring improved cooling capacity. Moreover, the innovative "L" shaped end tanks play a dual role - accommodating the thicker core while augmenting thermal mass. This translates to heightened heat absorption, storage, and dissipation capabilities, surpassing what the OEM setup can deliver.

The results speak for themselves - users have reported an impressive up to 15° reduction in IATs compared to stock measurements. This means that the Dinan heat exchanger takes your driving to a new level by effectively maintaining lower temperatures, allowing your vehicle to achieve peak performance consistently. No more compromise, no more cooling-related setbacks. Elevate your driving pleasure by unlocking your vehicle's true potential with the Dinan B4x/B58 heat exchanger - your partner in pursuing ultimate performance every time you hit the road or track!

ENDURANCE TESTING

Experience enhanced Charge Air Temperature reduction through our Intercooler Temperature Drop (Intercooler dT) solution. We measure temperature differences across the intercooler, demonstrating the effectiveness of our Dinan heat exchanger combined with the OEM intercooler. This optimized system efficiently dissipates heat, leading to lower Intake Air Temperatures (IATs) and extended high-performance track sessions. Drive harder, cooler, and longer with Dinan.
