4 ply high quality reinforced silicone coolant hose 8mm (5/16") ID.  Z1 Motorsports recommends replacing all the stock rubber lines that supply coolant to and from the turbos, any time turbos are being changed or the engine is out of the car.   We also recommend replacing/rerouting all the coolant lines under the intake plenum any time the plenum is being removed for injector or valve cover gasket replacement.  Z1 offers these straight sections of replacement coolant lines made from reinforced silicone in one foot increments.  Available up to a 6' continuous length.

The stock coolant lines are exposed to substantial heat in the engine bay.  Over time the heat breaks down the stock rubber line eventually resulting in failure.  Z1 silicone turbo coolant lines will not break down because of the heat.  These are the last coolant lines you will ever need.  Unlike conventional stock rubber hoses that deteriorate over time, dry rot, and ultimately burst these silicone hoses will stay soft and not degrade. 

Z1 Motorsports offers a full line of silicone hoses that will be the last hoses you will ever have to purchase.  They will outlast the car and they cost less than new OEM replacements!  There's no reason to consider anything else.

Color: Black, Blue, or Red

NOTE: Please be sure to select your desired Color/Length from the Available Options drop-down to ensure you receive the correct hose(s).
