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!

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.

Features

  • 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

Manufacturer's Warranty — Dinan

Dinan warrants its Performance Products to be free from defects in materials and workmanship, and the term depends on the car. If the vehicle is still covered by the original manufacturer's new car limited warranty (4 years or 50,000 miles — 80,000 km in Canada — from first retail sale; US and Canadian specification vehicles only), the Dinan part is covered for the remaining term of that new car warranty, and an Authorized Dinan Dealer repairs or replaces the defective Dinan component without charge for parts or labor, including any original manufacturer component directly affected by it. If the car is out of its new car warranty, Dinan Performance Products carry a 2-year, unlimited mileage warranty from the date of original purchase; labor is reimbursed at the dealer's standard flat-rate, but repairs to affected original manufacturer components are not reimbursed. DINANTRONICS Sport, DINANTRONICS X and DINANFLASH handheld units are 1 year, unlimited mileage; refurbished products are 90 days; and racing-only parts are guaranteed against defects in workmanship only — they are not warranted against wear or failure and may affect the BMW factory and emissions warranty. Dinan's warranty is transferable when the vehicle it was installed on is sold. A lawful invoice as proof of purchase is required, and the defective part must be returned to Dinan for verification before any adjustment. Not covered: return shipping, towing and rental car charges; unauthorized modification of a Dinan part, or damage from using other manufacturers' products alongside Dinan systems; non-DCT clutch assemblies, brake rotor warp and friction materials; maintenance items such as spark plugs, filters, lubricants, fluids, coolant, drive belts and light bulbs; negligence, abuse or improper installation; engine damage from altering Dinan's original boost pressure; improper or contaminated fuel; collision damage; environmental damage, flood, fire or road-salt corrosion; and any vehicle operated in a competitive event or subjected to aggressive track conditions. The warranty is void if the VIN or odometer has been altered, if the vehicle was declared a total loss or salvage, or if it has been used in competition. Note that installing performance products may affect the vehicle manufacturer's own new car warranty. Because Dinan handles claims through an Authorized Dinan Dealer, if you bought it here, contact PitStopTuning and we'll file the claim with Dinan for you rather than approaching Dinan directly.

Warranty terms are set by the manufacturer and may change. Contact us if you need help with a warranty claim.
