Finally an overflow you can be happy to have in your engine bay! The PHR Radiator Overflow for the MKIV Supra tucks in close the the headlight, making room for 4" intercooler piping or a full size battery to fit up front (PHR will soon be offering a battery tray to fit a group size 26 battery, stay tuned). No more tucking ugly plastic overflows and pretending it's not an eyesore. The PHR overflow features a CNC Formed aluminum tank body with a billet cap.
Installation notes: Hose from radiator should attach to the bottom port on the tank. The top port can just vent or can have a spillover hose run underneath the vehicle. If running hose please do not let the spillover drain in front of the tires
The PHR Radiator Overflow is specifically designed for the 1993-2002 MkIV Toyota Supra, not for any other similar chassis fitment (SC, GS, etc.). We do not recommend purchasing this for those chassis' unless you are okay with doing modifications.
It is not designed for use with a OEM size (Group 24) battery or the OEM battery tray. The PHR Radiator Overflow is perfectly paired with a PHR Billet Battery Tray or PHR Battery Relocation Kit. If you would like to retain a OEM size battery, you will need a new battery tray.
