Ensure your Spec E46 is cooling efficiently while boosting cooling by 15%. CSF manufactures their products to exceed the performance of your original unit. With drop-in fitment, this is the easiest way to improve your stock cooling system.
All CSF radiators undergo a rigorous testing process in our state-of-the-art testing lab.
- Our procedures and requirements set the bar for cooling system reliability and performance:
- Individually leak tested
- Vibration cycle tested
- Thermal cycle tested
- Wind tunnel tested for optimal radiator core cooling efficiency
- Burst pressure and impulse cycle tested for strength
- Salt spray tested for corrosion protection
- 10 foot box "drop test" to ensure packaging protection
- 30 point fitment inspection on critical dimensions to ensure OE fitment with no modifications necessary
