ISR Performance Silicone Radiator Hose Kit - Nissan RB25DET - Black

When you're rebuilding the cooling system on your Nissan RB25DET, especially if you're pushing it hard or have done some engine work, replacing old, brittle rubber radiator hoses is a must. This silicone hose kit from ISR Performance is designed to replace your stock hoses, offering a more durable and heat-resistant option. The black finish gives a clean, professional look under the hood.

These hoses are made from multi-layer silicone with polyester reinforcement, which means they can handle higher temperatures and pressures than standard rubber hoses without degrading. This improved heat resistance helps prevent premature hose failure, a common issue with older rubber components, especially in performance applications. They are molded to fit the specific contours of the RB25DET engine bay, ensuring a straightforward installation without needing to cut or adapt the hoses.

This kit includes the necessary hoses to replace the main upper and lower radiator connections. It's a solid choice for anyone looking to upgrade their cooling system reliability and appearance.
