Product Description

Brand-new 2 pc. set of molded  ECR throttle body coolant hoses 

(Highway Stars has brought back to market another concours product- MOLDED  throttle body coolant hoses

1- Heater inlet pipe to throttle body inlet hose
1- Throttle body outlet to heater outlet pipe hose

Factory original OEM molded throttle body coolant hoses:

  • Exact length
  • Correct ECR (ECR=specially formulated to be electrochemical resistant) rubber polymer compatible for use with hot or cold coolant.

These hoses are molded specifically to eliminate restrictions or kinking associated with making bends in bulk hose.

ECR rubber is very important, because regular hoses sold elsewhere may degrade from the inside out (which you can not see) and most people would not be aware of, until the hose bursts.

OUR exact length, exact molded shape PRODUCT is different than other generic products.  

You will not find this Highway Stars product anywhere else. (It is only sold through Highway Stars)

Note*  It is recommended service procedure to replace all four hose clamps when replacing these hoses.

Another exclusive OEM reproduction from Highway Stars


You get what you pay for:

Beware of generic cut length hoses sold elsewhere such as: 5/16" bulk fuel-vapor hose that is non-ECR rubber and NOT MOLDED, nor compatible with degradation or temperatures associated with hot coolant.  

Using bulk fuel-vapor hose may kink, restricting coolant flow through the throttle-body (because they are not molded) and may also lead to premature hose failure leaving you stranded on the roadside.
