Why Upgrade Your Radiator?

Factory BMW plastic end-tank radiators are known wear items. Common issues include:

  • Cracked end tanks

  • Coolant leaks

  • Overheating under load

  • Reduced cooling efficiency over time

An all-aluminum design eliminates the plastic failure point.

 

Cooling is absolutely crucial during high performance driving. Maintained high load, high RPM instances dramatically increases heat produced by the engine requiring a lot more from the vehicle’s cooling system.

Megan Racing Radiators are comprised completely of aluminum. From the tanks to the primary core. Aluminum tanks are a great upgrade over the plastic usually found on factory radiators which are known to crack and leak especially as they age. The larger heat exchanging core is not only more efficient at transferring heat from the coolant, but also increases total coolant carrying capacity.

Designed to as a complete bolt-on application, Our radiators are designed to comply with factory components such as fans and A/C condensers however due to the slight increase in overall size. Upgrading to high capacity, slim radiator fans is suggested.

Aluminum radiators mark a modern advancement in cooling. Not only does the material dissipate heat at close to double the rate compared to brass, but also reduced the overall weight of the vehicle and provides a stronger and more durable core and tube design
Please FLUSH the radiator before installation and properly take all the air pockets out. If its not properly installed, might cause the motor to over heat due to low coolant or air pockets in the cooling system.

 


Performance Benefits

  • Lower operating temperatures

  • Improved cooling under track conditions

  • Increased reliability for modified engines

  • Better heat management for high-RPM driving

If you’re tuned, boosted, or tracking your M3, cooling is not optional.


Installation Notes

  • Manual transmission models only.

  • Inspect hoses and thermostat while servicing.

  • Use proper BMW-approved coolant mix.

  • Bleed cooling system thoroughly after installation.

Cooling system maintenance on BMWs isn’t a suggestion. It’s mandatory.
