Porsche 997 Twin Turbo high performance silicone intake hose kit adds +15Bhp. Fits all Porsche 997TT models worldwide. These are super strong super durably heavy duty replacement hoses for the weakest link and "Achilles heel" in all Porsche 997 Turbo factory stock hoses. The factory 997 TT hoses and clamping systems work adequately on stock cars but once you modify the car and have more boost you need our heavy duty race quality silicone hose kit to eliminate the hoses from expanding.

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.
