Presenting the ColdFront™ Heat Exchanger, by Awe Tuning, for the BMW F8X M3/M4. Designed and engineered in-house at AWE Tuning and built by the experts at Griffin Thermal Products, the F8X M3/M4 ColdFront™ Heat Exchanger is the standard for consistent performance.
The ColdFront™ Heat Exchanger is a meticulously engineered and guaranteed proven solution to heat-based power loss in the M3/M4 platform. Boasting a 125% increase in fluid volume, 24.4% increase in frontal surface area, and resulting IAT drop of 15°F. Enabling the full potential of the BMW M3/M4...now.
Why does your M3/M4 need a heat exchanger?
Your M3/M4 will produce 425 hp and 406 lb-ft of torque from the factory. Add additional performance, and you’re susceptible to higher intake air temperatures (IATs). Higher power can mean higher intake air temperatures, and insufficiently cooled air entering the M3/M4 motor will decrease its performance potential.
The stock charge cooler system rapidly heat soaks when subject to power pulls at 30 second intervals. By the sixth pull, IATs have climbed to over 130°F! In other words, without an upgraded heat exchanger, you’re susceptible to heat soak, giving up some of the gains you’ve made from other aftermarket power upgrades.
The ColdFront. Keeping things cool in the heat of battle.
Cue the AWE Tuning's ColdFront™ Heat Exchanger. Swapping the stock heat exchanger for the engineered ColdFront™ Heat Exchanger not only produces cooler and more stable IATs (peaking at just over 115°F after six power pulls) but also solid run-to-run consistency.
When taking the tests to the track, 0-100 mph runs show the ColdFront™ Heat Exchanger dropping IATs from start to finish, keeping the incoming air to the M3/M4 motor cooler than stock, even while at idle, thereby reducing heat soak.
The ColdFront™ Heat Exchanger achieves better results than stock by presenting a 24.4% larger frontal surface area while also increasing fluid volume by 125%. Further, the construction of the AWE Tuning core utilizes specially designed tubes and fins. More surface area and better fin aerodynamics for superior heat exchange, and higher thermal reserve through increased liquid volume ensures IATs stay low and power stays consistent and ultra-reliable.
The M3/M4 ColdFront™ Protection Screen.
The AWE Tuning M3/M4 ColdFront™ Protection Screen is the solution for guarding the full face of the M3/M4 ColdFront™ Heat Exchanger from road debris. Constructed from a durable stainless wire mesh and surrounded by a stainless steel frame, it protects against any small objects that may find their way past the vehicle’s grille. This screen keeps the heat exchanger fins free of damage, allowing them to perform with maximum efficiency.
