On a gen4/5 swap into an MR2, the stock heater core hoses do not work. TCS overcame this by having custom silicone hoses molded that connect the Gen4/5 water neck to the MR2 heater pipes on the firewall. Kit also includes the 2 main coolant hoses in the engine bay (passenger side thermostat housing hose, and the drivers side is a silicone version of the TCS hardline bypass hose). The drivers side goes directly from the water neck to the main hardline under the car, and eliminates the long hardline on the front firewall (thus eliminating 2 hoses and a hardline when installed).
Available in black.
