Product Details
The factory B4x/B58 heat exchanger is not built to cater to the rigorous demands often associated with a modified build. The thin core is easily overwhelmed with IAT's rising dramatically once pushed beyond a few successive WOT pulls or even a few minutes at the track. This elevation in temperature gives way to the factory ECU fail safes pulling timing and reducing overall power in order to keep the system from overheating to the point of permanent damage. On an application where enjoyment is directly attributed to pushing the platform to its limits this constraint to cooling presents a challenge for the automotive enthusiast.
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° 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!
Features:
- Average of 8° reduction in IAT's with a maximum reduction of 15° over 15 successive WOT pulls
- 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
- Installation hardware included (inclusive of xDrive specific transmission oil cooler brackets)
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. (https://documents.dinancars.com/d780-0002.pdf)
