Upgrade your B58 engine with our do88 Front Intercooler Water Cooler!

B58 vs. F80 M3/M4 S55 Engine
The B58 engine shares many similarities with the S55 engine found in the F80 M3/M4 models. Both engines have a water-to-air intercooler that is connected to a separate cooling system that has a heat exchanger (water cooler) mounted in the front of the car. This heat exchanger cools the system water which in turn cools the intake air as it flows through the intercooler. The main difference in the B58's system is that the intercooler is integrated into the intake manifold, while the F80 S55's intercooler is a separate unit mounted on top of the engine.

Challenges with the B58 Intercooler Cooling System
A common problem with tuned B58 engines is that the intercooler quickly gets “heat soak” during track driving. High intake temperatures cause the ECU to reduce power or put the car into limp mode. Even hard street driving can cause the ECU to pull back the ignition and reduce power output due to too high intake temperature.

Our Solution
It is clear that the system needs increased cooling capacity to prevent Heat soak. Part of our solution is our do88 Front Intercooler Water Cooler. It is designed to provide increased cooling capacity and help prevent Heat soak. Features:

  • 66% larger cell pack than original.
  • 2-row cell package that is 48mm thick, this provides an increased active cooling area by a full 120%.
  • Triple-pass flow, this means that the water passes through the radiator three times instead of once like on the original radiator, this ensures that you maximize the contact of the cooling water with all the cooling area.
  • All-aluminum radiator with durable TIG-welded end tanks.
  • Increased liquid volume for optimal heat dissipation.

Installation
Easy installation no modifications required to install the do88 Radiator (see installation instructions). Our radiator includes mounting points for the original transmission cooler.
