CSF Porsche 991 Carrera, 981 Boxster / Cayman / GT4 / Spyder Performance Radiator (Left)

Full aluminum construction with a 40% increase in cooling capacity and 15-25% increase in cooling efficiency. Along with the increase in cooling performance this CSF radiator also adds reliability to your cooling system by eliminating the plastic end caps through it's aluminum construction that are prone to cracking and leaking.

Your radiator is an integral, and arguably, the most important part of the cooling system. It is designed to expel heat from the coolant via the small fins. Most radiators fail when the end tanks crack causing leaks, but higher mileage radiators which have missing or bent fins often are clogged up with debris which can also cause overheating issues as the radiator cannot expel heat effectively. If your radiator is in rough shape we recommend replacing it. We also highly recommend inspecting/replacing the upper and lower radiator hose at that time.

Radiator Failure Symptoms:

• Overheating
• Coolant Leak
• Cracking
• Bent Fins
• Clogged Fins cause by debris
