Water swirl pots are fitted as common practice to most race cars, where the demands on the cooling system are much higher due to increased power / engine revs. The use of a swirl pot will help reduce air bubbles in the system and allow the water to have a more stable operating temperature. We are able to replicate any standard manufacturer header tanks, or produce bespoke tanks for any application. Where possible all original hoses & tank caps will be utilised. Please contact us to discuss.
