The HPS black high temp 3-ply reinforced silicone radiator hose kit (part number 57-1686R-BLK-1) replaces stock OEM rubber upper and lower coolant hoses with high-heat resistance material that meets or exceeds OE specifications (Maximum temperature rating: 350F).
Excellent for extreme ambient and radiant temperature conditions, HPS premium quality silicone hoses can withstand the harsh high temperature and high pressure operating conditions of the engine while still maintaining peak efficiency during daily driving or racing competition.
The HPS silicone hose kit includes 100% stainless steel non-perforated embossed hose clamps for easy installation, which do not cut through the silicone hoses.
Compared to the universal hoses available from local auto parts stores, the HPS silicone radiator hose kit has all the correct bends and curves for perfect fitment.
The HPS silicone hose kit is backed by HPS Performance Products limited lifetime warranty.
