Adding a third radiator to your watercooled Porsche is a great way to make sure it will run strong on the street and at the track even in the hotest weather and will ensure greater longetivity in years to come. A factory option for Power Package cars, this kit includes radiators, hoses and all necessary hardware to install this OEM centerpiece. This is a necessary modification for those who will be taking their car to the track in extreme heat, but even standard street cars can benefit during the summer. The location of the coolant thermostat ensures that your engine will take no longer to warm up than before, but you will have significantly increased cooling capacity when you need it.

Includes all necessary parts and hardware. Minor trimming and painting may be required, check notes below.

For the ultimate setup pair this radiator kit with our Rennline Radiator Grill Screens.

About Track & Race Coolant Radiators

High-Performance Track & Race Coolant Radiators for Motorsport-Level Engine Cooling

Track and race coolant radiators are engineered to withstand the extreme thermal demands of motorsport, high-revving engines and repeated full-throttle operation. Designed to offer superior cooling capacity compared to standard radiators, these units feature enhanced cores, high-flow fin structures, improved heat dissipation and reinforced construction. Whether preparing for track days, competitive racing or spirited performance driving, upgrading to a race-spec radiator is essential for maintaining safe engine temperatures under severe conditions.

These radiators provide robust cooling efficiency, helping prevent overheating, power loss and premature wear—making them a crucial component for any high-performance build.

What Track & Race Coolant Radiators Do

Performance radiators deliver significantly improved cooling by:

  • Increasing coolant flow through larger or multi-row cores
  • Maximising heat transfer with high-efficiency fin designs
  • Managing extreme temperatures produced during racing or track sessions
  • Preventing overheating when engine output and ambient heat are at their highest
  • Improving coolant stability during repeated high-load cycles
  • Supporting upgraded engines, forced induction setups or heavy performance tuning

These radiators maintain optimal operating temperatures where standard cooling components cannot cope.

Why Standard Radiators Fail Under Track Conditions

Racing conditions expose radiators to far greater stress than road use. Failures often occur due to:

  • Heat saturation where standard cooling cores cannot dissipate enough heat
  • Coolant boiling or overflow caused by extreme temperatures
  • Weak core construction leading to cracks or leaks
  • Blocked or restricted fins reducing airflow
  • Plastic end-tank fatigue failing under high thermal load
  • Vibration damage from track surfaces and aggressive driving
  • Insufficient coolant flow in performance-modified engines

Symptoms include rising coolant temperatures, steam, coolant loss, reduced power, limp-mode activation or overheating during extended high-load operation.

Why You Should Upgrade to a Track & Race Coolant Radiator

Replacing the standard radiator with a high-quality, motorsport-grade alternative engineered for superior heat management ensures consistent performance and protects the engine from severe damage.

Key benefits include:

  • Stable coolant temperatures under extreme load
  • Improved reliability during track days, racing or spirited driving
  • Enhanced heat dissipation and faster cooling recovery
  • Stronger construction with alloy tanks and reinforced cores
  • Prevention of head gasket failure, detonation and thermal stress
  • Longer life for coolant hoses, water pumps and thermostats
  • Increased confidence and capability for high-performance driving

A race-spec radiator is one of the most impactful upgrades for track-driven vehicles or modified engines.
